You may be using an environmental chamber for testing and suddenly lose power. This can be caused by something as simple as a broken power line or a more severe weather event such as a snowstorm, flood or tornado. Sudden loss of power can not only interrupt the test, but also damage your chamber. Fortunately, when your lab loses power, there are a few precautions you can take to avoid loss of power and potential chamber damage. Keep these in mind, especially when severe weather comes into the forecast for your area. When your test box loses power In the event of a power failure, your test chambers will shut down completely, as they require constant power to operate. If possible, you should disconnect the test chamber from the mains voltage as soon as possible to prevent any potential damage that may be caused by power surges when power is restored. A power outage in a room presents several dangers: The test chamber contains sensitive electrical components. Although manufacturers take precautions to protect system components from power outages, some components, such as the XChange board, can be damaged by multiple power surges. It's best to use a surge protector to prevent this from happening. Components can fail or degrade over time due to repeated power outages or power surges. Likewise, using a surge protector is a surefire way to protect the chamber and its electrical components. You also need to keep in mind the type of testing you are doing. For example, there are increased hazards when conducting battery tests. Power interruptions during battery testing increase the risk of hazardous events such as thermal runaway. Losing power mid-test also means the battery safety features will no longer work. Not only will this affect your test results, but it will leave your battery components vulnerable to damage, costing you money in the form of damaged products and delayed test times. So it's best to avoid battery testing in bad weather, or invest in a generator to keep your lab powered in the event of a power outage. Finally, remote testing techniques will not work during a power outage. This can present challenges if test room users are not in your lab when a large number of active rooms lose power. For example, you can no longer know what is going on in your room. In addition, test data may also be lost. This can be frustrating and delay your testing plans. After your test chamber is powered off Once power is restored to your chamber, it is best practice to verify that all chamber functions are working as expected. If some functions do not function properly after a power outage, please contact your manufacturer for further assistance. You should keep them on call at all times, not only for routine maintenance, but for rare situations like unexpected power outages. If you are testing while the power is out, you will usually want to restart the entire test when power is restored. However, this depends on factors such as the internal conditions of the stability test chamber prior to the outage, the duration of the outage, and the specific tests you are running. Review the testing criteria you are using to inform your recovery decision. In most cases, a change in temperature or humidity conditions will affect your test and you will need to start over. Fortunately, there are some precautions you can take to ensure that downtime is minimized and damage to your photostability chamber is avoided. Preventive measures you can take If you anticipate that severe weather may threaten your laboratory's electrical supply, disconnect your test chamber from the mains voltage. It is recommended that you suspend any testing until you are confident that the threat to the power source has passed. If you are using remote testing capabilities, the lab should have a plan and system in place to handle sudden power outages. This will vary from lab to lab, but it is recommended to have an emergency power source such as a generator and a surge protector for the lab. Otherwise, you could lose important data and run the risk of adding unnecessary wear and tear to test chamber components. To ensure your lab is well-equipped to handle potential power outages, consult a trusted manufacturer for optimal lab design. In addition to preparing you for potential power outages, reliable manufacturer XCH Biomedical will provide you with layout recommendations for increased efficiency and safety.

Stability test chambers are specialized equipment designed to evaluate the reliability and stability of products under various environmental conditions. These chambers simulate harsh environmental conditions like high and low temperatures, humidity, and light exposure that the products may encounter during their lifecycle. This testing process is essential to ensure that the product meets the required quality standards and performs reliably throughout its intended lifespan. The stability test chamber works by providing a controlled environment where the product is subjected to different stress factors, such as temperature, humidity, and light exposure. The chamber is fitted with sensors that monitor and control the conditions inside the chamber. The sensors transmit data to a computer, which analyzes and records the results. The product is placed inside the chamber, and the conditions are varied according to the test protocol. The stability test chamber is widely used in various industries, including pharmaceutical, medical, and food industries. In the pharmaceutical industry, stability testing is required by regulatory bodies to ensure the safety and efficacy of drugs. Stability testing is also crucial in the food industry, where it is used to evaluate the shelf life of food products and their resistance to microbial growth. The photostability chamber can also be used for accelerated testing, which involves exposing the product to harsh environmental conditions to speed up the testing process. Accelerated testing is useful in situations where the product lifespan is shorter than the traditional testing period. For instance, in the electronics industry, the lifespan of electronic components is relatively short. Therefore, accelerated testing is used to determine the performance of the components under harsh conditions and predict their lifespan. Stability test chambers are available in different sizes, depending on the product being tested. Some chambers are designed for small products like pharmaceuticals, while others are designed for large products like vehicles. Like walk in stability chamber. The chambers can also be customized to suit the specific needs of the user. In conclusion, the stability test chamber is an essential tool in the product development process. It plays a significant role in ensuring the reliability and safety of products by evaluating their resistance to harsh environmental conditions. The data obtained from stability testing is crucial in making informed decisions about the quality and performance of products. It is, therefore, important for manufacturers to invest in stability test chambers to ensure the quality and reliability of their products.

Stability test chamber play a vital role in ensuring the quality and safety of products. By simulating real-world storage conditions. A Stability chamber is a type of environmental chamber used in the pharmaceutical, cosmetic, and food industries to simulate and control storage conditions for products. The purpose of a stability chamber is to determine the shelf life of a product and to ensure that it remains within acceptable quality limits during its intended storage time. Stability chambers are designed to simulate different temperature and humidity conditions, and can be programmed to maintain specific conditions for extended periods of time. They typically have a temperature range of between 5°C and 60°C, and a humidity range of 20% to 80%. The temperature and humidity are monitored and controlled using sensors and actuators, and the data is recorded and analyzed to determine the stability of the product. In pharmaceuticals, stability chambers are used to test the humidity and temperature controlled chamber of drugs, vaccines, and other medical products. This is critical to ensure the safety and efficacy of these products over time, and to ensure that they remain within their shelf life. Stability chambers are used to store samples at specific conditions, and the samples are periodically tested to determine any changes in the product's quality. In the cosmetic industry, stability chambers are used to test the stability of skin care and cosmetic products. This helps manufacturers determine the shelf life of their products, and to ensure that they remain stable and effective over time. In the food industry, stability chambers are used to test the stability of food products, such as packaged food and beverages. This helps manufacturers to determine the shelf life of their products, and to ensure that they remain fresh and safe to consume over time. Stability chambers are critical to ensuring the quality and safety of products. They help manufacturers to determine the shelf life of their products, and to ensure that they remain within acceptable quality limits during storage. This helps to ensure that consumers receive safe, high-quality products that meet their needs and expectations. You can access stability chamber manufacturer to know more details.

Stability Chambers are specialized enclosures that create a controlled temperature and humidity environment. Industries as diverse as pharmaceuticals, packaging, environmental testing and controlled storage use immersion or walk-in test chambers for stability testing. These test rooms are designed to find defects or weaknesses in products under different conditions by providing a controlled testing environment. Stability chamber qualification requirements fall under the category of installation, operation, and performance. Stability test chambers are subject to these three qualification tests before being put into operation. Stability Room Qualification Requirements To be certified to perform stability testing, an environmental chamber must go through a three-part qualification process. Qualifications must also include calibration records for all instruments used and evidence of their calibration status. The three qualification types are Installation Qualification (IQ) Operation Qualification (OQ) Performance Qualification (PQ) Together, these three stability chamber qualification requirements and tests support and document proper operation. Installation Qualification (IQ) Overview: The first qualification verifies that the stability chamber complies with its design specifications. All parts have been counted and checked for proper fit. Appropriate documentation must also be provided, including user manuals and any certifications and standard operating procedures (SOPs). Requirements: All components must be properly installed and functional for the stability chamber to pass installation qualification. If the chamber has a control panel with a human machine interface (HMI) or other guidance devices such as buttons and selector switches, they must function as designed. All alignment and safety equipment also needs to pass inspection. Operation Qualification (OQ) Overview: Run qualification tests to stabilize the room's functions and verify that systems and subsystems operate as expected within the normal operating range—including testing all doors, switches, controls, and alarms. REQUIREMENTS: The operational qualification test verifies that the temperature and humidity inside the chamber are equalized. To ensure accurate temperature and humidity readings, the operator waits a few minutes for them to stabilize, then runs the test for the specified time. Conduct Open Doors studies prior to completing operational qualifications. The test consists of opening the door for short periods of time while recording temperature and humidity at short intervals. The door opening test was repeated at least three times to calculate the average recovery time of the chamber. Performance Qualification (PQ) Overview: Performance qualification verifies that the stable chamber meets performance specifications at full load. Typically, testing is performed at the operating set point of the chamber, loading a mock product to replicate a typical environment. Measure temperature and relative humidity uniformity using thermocouples and relative humidity (RH) sensors. Requirements: The stability chamber must operate at full capacity for at least 24 hours to pass performance qualification. After the initial study is complete, the trial will be repeated with an open door study to calculate its mean recovery time. The stability laboratory qualification and performance process is conducted annually using the same procedures as past testing. After each reaccreditation, the results should be compared to previous years to track the Chamber's overall performance.

One of the essential pieces of equipment in any materials testing laboratory is an oven, also known as a oven. They remove surface moisture while heating the material. Drying chambers are used in a variety of different applications such as sterilization, annealing, aging tests and incubation. Choosing a laboratory drying oven is an important purchasing decision. With a large number of ovens available with different configurations and characteristics, it is important to understand how to evaluate an oven based on various specifications and capabilities. How to choose a drying oven for laboratory Read on to learn five factors to consider before purchasing a lab drying cabinet. 1. Heating method On the surface, each oven works basically the same way—heating and removing moisture from samples inside. Ovens, however, accomplish this differently. Ovens utilize three heating methods: infrared (IR) heating, convection heating, or a combination of the two. Ovens that use convection heating are equipped with fans that circulate hot air around the chamber to evenly heat the sample. Meanwhile, infrared ovens allow you to target specific areas for heating. They operate by line-of-sight heating, which means they transfer heat to the part of the object that is directly within the line-of-sight of the heater. Ovens with hybrid infrared convection heating systems tend to be favorites of professionals because they offer greater drying flexibility. 2. Oven structure How an oven is constructed determines its performance. When you're examining an oven you might want to buy, there are some important structural features to look out for. First, look at the materials used. Depending on your needs, you can choose an oven made of durable, non-corrosive and easy-to-clean stainless steel. Then, look at its insulation. A well-insulated oven prevents heat loss that could damage samples. If you are performing high temperature processes, choose a double wall oven to ensure it can withstand extreme heat. Also, to avoid any heat loss, choose doors with heavy-duty doors and safety hinges for a tight seal that keeps air out. Another factor to watch carefully are the controls. The oven with digital PID (Proportional, Integral, Derivative) control is programmable for more accurate testing and includes many features such as calibration routines and data logging. You may also want an oven with overheat protection to help keep you safe in the lab. They automatically shut off if the temperature exceeds a certain point, preventing fires and accidents. 3. Chamber size How large or small is your sample size? This will help you determine the size of the oven to buy. Choosing a chamber that is too small will be a hindrance to your productivity. At the same time, a device that is too large will make your lab feel cramped and cost more due to its higher heat output. So before looking for an oven to buy, measure the available space in your lab. Take note of the width and height to get a better idea of which ovens to consider and which might not fit. 4. Heating uniformity No matter how many are placed, the samples in the oven must receive the same heat treatment. Therefore, the heat should be consistent throughout the oven. This is known as heating or temperature uniformity. Several factors can affect the uniformity of heating in an oven, primarily the way the oven is constructed. If the insulation is inconsistent or there are small gaps in the oven door, cold air can seep in and disrupt the temperature in the room. These cold spots cause some samples to get hotter than others. For example, if you place samples that are subjected to varying degrees of heat, this can result in poor product quality or inconsistent and unreliable results. That's why it's in your best interest to look for an oven that distributes heat evenly. But how do you know if it exists? Usually, reputable manufacturers will provide information about the heating uniformity of their ovens on their official product pages online. For example, on the official page for Across International's 250C 3 Shelf Vacuum Oven, you'll find it clearly states that its temperature uniformity is ±7% of set point. 5. Recovery time Whenever you open the oven door to add or remove samples some heat is released. When this happens, the oven increases energy output to compensate for heat loss. The time it takes to return to the proper temperature is the recovery time of the oven. Ovens with shorter recovery times allow for greater accuracy and thermal uniformity, but at the cost of adding more load to the system. Depending on your specific use case, this may be a negligible or non-negotiable feature. If your samples have very complex heating requirements, it is best to purchase an oven with a short recovery time. Or, if your oven has a relatively long recovery time, it can prevent excessive heat loss. Being more careful when preparing samples can help limit how often the oven door is opened. Adding the proper amount of sample to the oven allows for better and even heat transfer. Invest in a high-quality vacuum oven with pump Since laboratory drying ovens play an important role in laboratory testing, taking the time to choose which oven to purchase will save you money and worry. It starts with understanding what exactly you need your oven to do. There is no perfect oven, only one that suits your needs. This will help you determine which heating method is right for you, what materials, sizes and widths you need in the oven's construction, and how it manages its internal energy system. Check out XCH Biomedical for high quality, durable and reliable laboratory vacuum oven. If you are still not sure which oven to buy for your laboratory, you can easily consult XCH Biomedical.

In Stability Testing - An Overview, we look at Stability Testing Requirements - Chamber Selection, Validation Requirements, IQOQPQ and IPV Considerations. In order to demonstrate the shelf life of a drug in a certain market, the manufacturer must store it at the relevant temperature and humidity for a specified period of time. This is done in what is also known as a stabilization chamber. Regulatory agencies in each market, such as FDA in the US, HPRA in Ireland, specify the temperature and humidity conditions that should be used and how long samples should be stored, such as a minimum of 6 to 12 months. During this time, samples were tested and their potency and degradation measured and recorded. This is called a stability test. The most common conditions are 25°C/60%RH. For new products, accelerated conditions may be 40°C/75%RH. Other conditions include 30°C/65%RH, 30°C/35%RH and 25°C/40%RH. For products intended to be stored in a blood bank Refrigerator, another condition is 5°C ±3°C. For products intended to be stored in a refrigerator, the test condition is -20°C ±5°C. ICH, the International Conference on Harmonization of Technical Requirements for the Registration of Pharmaceuticals for Human Use, has developed rules for running stability tests. ICH Q1A states that during stability testing, conditions should be kept constant at ±2°C and ±5%RH. Also, if these conditions are not met for more than 24 hours, the test may need to be extended, creating a lot of paperwork. If conditions deviate from ±2°C/±5%RH, even for a short period of time should be accounted for. Probably due to the door opening to "pull" the sample. Events like this are usually logged in the room log. If no explanation is apparent, it may be necessary to seek assistance from a service engineer. In the event of a failure in the laboratory, a quick response from the supplier is required and although he should stock major spare parts, the auditor would also like to have some stocked on-site as well. It is also recommended to have redundancy, ie another room on site as a backup. The chamber must be fully validated and ready for use. Photostability Test Chamber To demonstrate shelf life under ambient light conditions, samples may be exposed to precise doses of UV and visible light in specially designed chambers. ICH Q1B specifies temperature control to prevent localized hot spots. Surveillance and 21 CFR Part 11 Indoor conditions should be independently monitored. This usually requires temperature and humidity transmitters connected to the recording system. In the Photostability chamber temperature, UV and visible light intensities will be recorded. This system must comply with the regulations of 21 CFR part 11 in the United States, whether it is a paper recorder or a computer system. 21 CFR Part 11 states that all related data collection and storage systems must be designed to prevent counterfeiting, corruption, untraceable alteration, or loss of data. In the case of computer systems, formal testing (IQOQ-Installation Qualification, Operation Qualification) should be performed to demonstrate compliance. Stability chamber Qualification Likewise, formal testing (IQOQ and PQ performance qualification) must be performed on new Stability chamber. During its useful life it should be maintained regularly (usually annual preventive maintenance service and calibration checks) and preferably mapped with several probes per year (IPV - Instrument Performance Verification). PQ and IPV typically require at least one 24-hour surveillance run, empty, loaded, or both. During this run, conditions must be shown to remain within ±2°C, ±5%RH of the set point. Test equipment used for these tests must be traceably calibrated at least annually and meet the IQOQ standards of 21 CFR P11.

In a medical laboratory, the risk of contamination of cell cultures is incalculable – no matter how meticulous the work. It is certainly not unheard of for risks to be miscalculated, and contamination often results in culture loss. Therefore, in this blog, we would like to shed light on how to systematically detect and avoid contamination in cell lines. Every medical laboratory is under threat day in and day out Microbial contamination in cell cultures—including those purchased from third parties—is not uncommon in laboratories. In fact, the opposite is true: Many cell lines grown in the laboratory are infected with mycoplasma. Tiny fungal spores are ubiquitous and can spread through the air. Of course, when working in a sterile environment, there is room for human error. It's easy to make a mistake. Horror scenarios in cell culture labs - contamination of all types: Microbial contamination (bacteria, mycoplasma, fungi, yeast, etc.) virus contamination protein contamination (prions) Chemical contamination (leachables and extractables from plastics, heavy metals, etc.) Cross-contamination with other cell cultures Where does pollution come from? 1. How "clean" is the original culture? Problems often start with the source material. Even with all possible efforts in the production of media, some materials cannot be rendered completely sterile. Therefore, there is always a risk of mycoplasma escaping the sterile filter. Prions can even survive steam sterilization at 121 °C. 2. Is the working laboratory really a sterile environment? One of the main causes of laboratory contamination is the human body. For example, many instances of cross-contamination could be avoided if lab technicians avoided handling multiple production lines at the same time on the sterile bench. One culture can quickly infect another if the liquid is not handled properly. Also, rushing things through is the worst enemy of dull work. The door of the laboratory incubator should not be opened without reason, and of course it should not be left open for a long time. No matter how much time pressure they may be under, lab technicians should only work on one cell line at a time. When unpacking disposable pipettes under the bench, the cap must be set aside after unscrewing. 3. Are you using the correct laboratory equipment? Of course, even equipment used in medical laboratories is entirely possible to cause contamination in cell culture. Therefore, we recommend: Use plasticizer-free plastic containers Choose a suitable location for the incubator (location near the washbasin may lead to soap contamination) Use incubator accessories made of sterilized copper When antibiotics are used, antibiotic-free lines should be bred from time to time. (This is because antibiotics can mask the contamination and the infection can spread.) What investigative methods can be used to track which infections? One of the most dangerous things about mycoplasma infections is that they often go undetected for a long time. In principle, pollution events can be controlled and tracked by a variety of methods, some very sophisticated and others less so. An experienced lab technician can tell if cross-contamination has occurred simply by looking under a microscope. If we extract all the DNA from a cell culture, the PCR method can be used to detect its mycoplasma DNA content. Laboratories performing viral transduction or bioassays should also check for viral contamination. Laboratories manufacturing drugs for novel therapeutics should check for low risk of bacteria, spores, fungi, mycoplasma, HIV, HCV, and BSE. How should pollution be dealt with? Every instance of contamination must be documented and graded. If nothing else, medical labs that keep pollution problems under wraps are jeopardizing their good reputations. Of course, special cleaning measures must also be taken in case of contamination: in the case of fungal infections, it is advisable to check that the laboratory is regularly disinfected with an alcohol-based agent As a general rule, regular spray or wipe disinfection of the scientific incubator interior with an alcohol-based solution helps to avoid contamination Monthly hot air sterilization is standard medical practice in many laboratories For sensitive stem cells, it is only in rare cases that infected cell lines can be treated with antibiotics. In most cases the solution is expensive - the culture has to be scrapped and the work has to be started from scratch in conclusion: Being able to consistently detect, validate and deal with contamination is absolutely essential, especially in medical laboratories that work with highly sensitive stem cells and do not use antibiotics. Transparent monitoring is essential. Covering up contamination or allowing it to spread only increases the danger and is unnecessary. The Constant Temperature Incubator should always be the safest component of the entire process step; if a sample is contaminated, then in most cases this occurs either upstream or downstream of the cooling incubator cultivation.

Drying ovens are used in laboratories or industry to heat materials and remove their moisture content. It is usually used where a drying process is required, such as food, agricultural products, pharmaceuticals, etc. There are different types of drying ovens on the market, such as hot air oven, vacuum oven with pump, dry heat oven, etc. Drying ovens are used to speed up the drying process by creating optimal evaporation conditions. The material is dried by convective heating that circulates air around the material by using a hot air oven. This type of drying is effective and efficient for large batches. Drying Oven: Definition A drying oven is an oven used to remove moisture from objects or materials. The stove uses heat to evaporate water and vents the resulting steam outside. They are often used on materials that are sensitive to water damage, such as electronic components or chemicals. You can also use them to remove moisture from food to extend its shelf life. Some ovens are also equipped with a dehumidifier, which helps to further reduce the relative humidity inside the oven. By keeping humidity low, the drying process can occur faster and more efficiently. Drying Oven application: Drying chambers are used in different applications such as scientific research, food processing, agriculture and many more. The sample under test is exposed to a preset temperature for a specific time set by the user. It is used for drying chemicals, pharmaceuticals and other substances. Aging or tempering of plastic and electronic components can also be done in these ovens. In agriculture, seeds and crop products are dried using laboratory ovens for longer storage. Stability testing in the food industry is done using these ovens. Drapes and gloves are also heated in these ovens so they can be sterilized. Drying Oven working process： This equipment is an oven used to remove moisture from materials. The chamber walls are exposed to a specific temperature at atmospheric pressure. Thermal energy enters the chamber load naturally or through forced convection and radiation. The surface heating system provides support from the back of the interior walls. The drying process goes faster as the temperature and air dries. The drying oven dries and heats the sample at the same time, allowing the sample to dry quickly and evenly. This process helps to measure the moisture content of the product being manufactured. Liquid content and content volatiles are removed during the drying process. Drying chambers are used in different applications such as scientific research, food processing, agriculture and many more. The weighed sample is exposed to a preset temperature for a specific time set by the user. You can find the resulting loss on drying with the aid of percent weight loss or moisture analysis. These methods are used to remove moisture from food. Dehydration helps preserve food and makes it easier to carry when traveling. Ovens of different capacities and dimensions are available upon request.

Environmental chambers have been used to research products for decades, with countless applications in aerospace, artificial intelligence, automotive, electronics, solar cells, medical, industrial, and consumer research. In these industries, samples or materials to be tested must be exposed to defined changes in environmental factors in order to study their effects and even prepare for future research. The conditions that an environmental chamber can replicate are: temperature set point (or change), relative humidity or moisture in the form of rain, electromagnetic radiation, vibration, weathering, salt spray, sun exposure/UV degradation, and vacuum. The type of testing involved will determine the chamber type; chambers come in a variety of sizes and are designed with different features and options. Environmental chamber humidity control and specimen incubators Prepared specimens or materials are placed in chambers and then subjected to specified levels of environmental stimuli to determine how responsive they are. The resulting by-products were also measured and studied. Chamber of Commerce Type Humidity or temperature chambers are used for climatic testing, while vibration and stress chambers are often used for mechanical testing, such as evaluating a product's performance under vibration or shock. "Pressure" is usually tested using a pressure variable or a vacuum. Stress and vibration chambers are also used in electronics, solar or fuel cells, and automotive products, where testing requirements are very demanding. The goal is to go beyond "normal" to measure the limitations of materials. Highly Accelerated Life Testing, formally known as HALT testing, is used to discover potential defects and ultimately improve products at the design stage. The chamber will simulate various stimuli such as vibration, aging, humidity, voltage and thermal cycling, which can cause many flaws in design or production. Instead, a compliance test known as HASS (Highly Accelerated Stress Screening) is performed during production to identify defects prior to commercialization. These tests use temperature and humidity variables to find potential defects. Environmental test chambers for manufacturing and production have been used for decades and are capable of generating pressures far greater than normal for commercial products. chamber design Environmental chambers can be designed as walk in environmental chamber, bench-top, floor-standing, reach-in or drive-in configurations. Depending on the function they perform, they can range in size from portable devices to gigantic rooms, such as the vacuum chamber at NASA's Space Power Facility, which is the largest of its kind. Floor-standing and table-top darkrooms are the most widely used. While most chambers are made of steel, the materials used for the inner and outer walls vary by application. When used in food packaging or pharmaceutical applications, the chamber may have glass doors for visual access. The intended application of the chamber also affects the types of heaters, coolers, condensers, evaporators, controllers, sensors and other modules used. Newer test chambers have evolved to keep pace with product testing requirements, such as those used in biological and military applications. These chambers are usually custom-made to meet all necessary environmental testing requirements and the equipment used for the measurements is very accurate and reliable. The newer design of the photostable stability chambers in pharmaceutical has a smaller footprint and is easier to handle than its predecessor. Their user interface resembles a touchscreen Windows monitor rather than traditional scrolling electronics. If they are network enabled, they can be programmed and operated online

The operation of a stability chamber is based on the basic idea that by maintaining a constant temperature and humidity chamber, a constant relative humidity value will be maintained as well. The ratio of how much water is in the air to how much it might theoretically store is known as relative humidity. With a rise in current temperature, the amount of water that air can contain increases, resulting in a drop in relative humidity. This is how both settings are automatically modified at the same time. The temperature in the stability chamber should not vary more than two to three degrees, and the humidity should not fluctuate more than 5%. The chamber’s outer and inner bodies are comprised of corrosion-resistant stainless steel, with the inner body insulated properly. Inside the chamber, there are several shelves for storing products that may be readily removed. Sensors are also fitted to the chamber to detect temperature and humidity levels. The controlled airflow inside the chamber ensures that temperature and humidity remain consistent. For improved uniformity of essential conditions, horizontal laminar airflow is suggested. Even when the shelves are fully loaded with samples, they will receive a continuous flow of air using this system. The linked blowers ensure that the sir is circulated properly. Receiving and transferring data is done with data loggers. Stability chambers have a wide range of applications. They play a vital role in the final stages of product production. It is also used in the automotive industry, cosmetics industry, packaging, biological or microbiological testing, research and various other fields. The Pharmaceuticals segment is responsible for creating, researching and marketing medicines that benefit medical science. Since these treatments will benefit large numbers of people in many parts of the world, proper drug production becomes a top priority. When individuals manufacture and ingest defective medicines, side effects and dangerous symptoms can occur. Therefore, it is necessary to conduct drug stability testing in various environments. In the pharmaceutical industry, the stability chamber is used for this purpose only. They assist in drug testing under various variables such as temperature, humidity, pH, radiation, etc. They are also used to see how long a product will last before needing to be replaced. Stability chamber testing also reveals information about the integrity of product packaging. This test can save you a lot of time and money by alerting you to errors in your medicine that could make it harmful in a particular setting. This test can also be used to determine the expiration date of a drug. The shelf life of a drug is the amount of time a drug remains effective from the date of manufacture when stored under specific conditions. This value must be determined using a stability test chamber and displayed on the packaging for consumer awareness. These chambers are also used to store pharmaceutical samples that require stable conditions that cannot be obtained through natural sources, as they maintain the required stable and uniform temperature. Proper maintenance and inspection of chambers should be a priority in the pharmaceutical sector to ensure correct drug testing. At last, Who provides the best stability chamber solution? Environmental Chamber Manufacturer Thchamber stability chambers have been carefully constructed and developed to meet the stringent requirements of climate testing and stability investigations. The chamber features FDA/ICH stability standards to provide out-of-the-box control and consistent temperature and humidity. Thchamber stability chamber has specific guidelines, structural integrity and measurement equipment that allow accurate recording of test data to keep the chamber running smoothly through rigorous testing cycles over many years.

In the pharmaceutical industry, stability testing helps demonstrate how drug quality changes over time under various environmental conditions, including temperature, humidity, and light. This testing must be done before the drug can reach the market. To test the quality of a drug at a specific temperature and humidity, a batch of the drug of interest is placed in a Constant Temperature Humidity Chamber for a specified period of time. Samples are checked periodically for quality analysis. Because stability testing can span anywhere from a week to six months to a year or more, the stability chambers used must be reliable and consistent. Another type of stability testing focuses on photostability, or how a drug is affected when exposed to certain amounts of light and ultraviolet light over time. For this type of testing, a stability chamber that meets specific guidelines and is capable of emitting the required light and UV light over time is required. Complying with ICH guidelines requires stability chamber with consistent performance Stability testing guidelines are outlined by the International Committee for Harmonization of Technical Requirements for Pharmaceuticals for Human Use (ICH) and are followed by regulatory agencies worldwide, including the Food and Drug Administration (FDA), European Commission (EC), and Health Canada. Six ICH Guidelines (Q1A to Q1F) provide specific details for adequate testing. These guidelines are very specific, requiring that the temperature in the stabilization chamber not deviate by more than 2 or 3°C, depending on the conditions, and the humidity not deviate by more than 5%. Therefore, a stability chamber for such tests needs to have the low temperature and humidity excursions observed during prolonged testing. The temperature also needs to be uniform throughout the unit. Stabilization chambers that use traditional non-directional airflow systems use fans mounted on top of the unit to push air down through wire shelves. When racks are filled with samples, this air flow is blocked, causing changes in temperature conditions throughout the chamber. This inconsistency may affect stability conditions and overall stability testing. In contrast, a stabilization chamber that uses a horizontal laminar airflow system includes a positive-pressure feed chamber on one side of the chamber and a negative-pressure return chamber on the other side to create horizontal airflow directly across the surface of each shelf. Using this method means that even when the racks are full of samples, they receive a steady flow of conditioned air, resulting in optimal temperature uniformity throughout the chamber and across all samples. The horizontal laminar airflow system also increases the capacity of the stabilization chamber by ensuring temperature uniformity, even when the racks are full, enabling testing of larger sample batches. Reliable unit will maintain performance during long-term stability testing Samples can be tested in a stabilization chamber for a week, six months, a year or longer, depending on the type of testing performed. If one chamber fails, pharmaceutical labs could lose months of work and will be pushed backwards in their timelines, prolonging the time it takes for a drug to reach the market. Stability chambers used for stability testing in the pharmaceutical industry must be durable and rigorously tested for their long-term performance. Additional features help pharmaceutical labs feel safe when using the stability chamber. For example, high and low temperature alerts can warn users when temperatures deviate. Even better, remote monitoring systems allow users to keep track of what's going on in the room even when they're not in the lab. Requirements for Photostability Test Chamber Photostability testing evaluates whether drug products undergo unacceptable changes when exposed to a combination of white light and ultraviolet (UV) light. Stability chambers used for this type of testing need to provide ideal light emission to meet the ICH requirements of Guideline Q1B - they must be able to maintain more than 1.2 million lux hours of light and emit more than 200 watts of UV energy to the sample. Unlike stability testing for temperature and humidity, light stability testing can be completed in as little as a week, and specific units can be programmed to turn off the light when the desired exposure level is reached. One issue to consider when performing photostability testing is safety. Exposure to UV rays can cause damage to human eyes and should be avoided. A chamber with lights that automatically shut off when the door is opened will help prevent UV exposure and keep your workers safe. Other potential uses In the rare case that your pharmaceutical laboratory does not perform stability testing, the stability chamber can be used for other applications. For example, because they maintain a constant temperature and humidity, they are ideal containers for samples that need to maintain stablity conditions. Stability testing in the pharmaceutical industry is a time-intensive investment, and selecting the right instrument should not be taken lightly. Stability chambers for testing the stability of pharmaceuticals under different temperatures, humidity and light need to be reliable, stablity and comply with ICH guidelines.
