>> Humidity Chamber (Condition Chamber)
- Humidity Chamber (Condition Chamber) is a simulated environment cabinet (Humidity Chamber ) to create the necessary conditions for testing the stability of different materials. A Humidity Chamber (Condition Chamber) can be used to simulate different temperature and humidity conditions. In addition, lighting simulation is important for some tests as well.


>> Other information
There are 2 types of Humidity Chambers (Condition Chamber): cabinets with constant temperature - humidity and cabinets with constant temperature - humidity. Constant Humidity Chambers (Condition Chamber) are often used for long term stability testing and can be used to maintain temperature and humidity at specified levels. On the other hand, a Humidity Chamber (Condition Chamber) with variable temperature, humidity can be used to run specific test programs in which the temperature and humidity are automatically modified at certain times.

The Humidity Chambers (Condition Chamber) are used in the industrial and research fields. These applications include stress-testing, material testing, aging testing, long-term stability testing, and using a specific database.

♦ Humidifier and other important components in Humidity Chamber (Condition Chamber)
The Humidity Chamber (Condition Chamber) produces stable temperature, humidity and lighting conditions. There are many different models and volumes according to test requirements. To ensure that the tests are performing well, it is essential to gather and record accurate data throughout the entire process.

Climate systems and coolers are perfectly adjusted for optimum cabinet uniformity - even close to the edge of the cabinet and when sample is filled. Homogeneous climatic conditions for all test pieces, regardless of their size and number of samples, are very important especially for long-term tests in accordance with GLP and GMP standards. An air-cooled system is often used to ensure tests are done under extreme weather conditions, while the independent temperature safety device monitors the data with an intuitive alarm. and sound.

The humidifier is connected to a capacitive (non-drift) humidity sensor. This ensures fast response time, accurate measurement, and short recovery time after opening. FDA compliance test results thanks to a microprocessor controlled dehumidification and dehumidification system. The humidifier is connected to an easy-to-use plug and play system and offers options such as connecting to existing water lines or a water tank installed inside the cabinet for easy portability. place.

With reliable controller, works in tandem with HMI (Human-machine interface) including intuitive touch screen. The operator can view an overview of all measurement data and can operate the Humidity Chamber (Condition Chamber)easily. This controller also ensures that related documents are stored safely, meeting the standards of FDA, GLP, GMP ...

♦ Stability testing and stress-testing in a Humidity Chamber (Condition Chamber)
To use the results of a stability test, the Humidity Chamber (Condition Chamber) shall ensure uniform conditions throughout the test. Even the smallest external influences can distort the results, which is why the quality assurance measures provided by the Humidity Chamber (Condition Chamber) are so important for the tests of different stability.

There are 4 main types of stability testing:
For the most effective analysis of sample variation, specific types of stability tests are developed as follows:
>> Long-term tests: This test method is used to observe variation of products (pharmaceuticals) under actual conditions. The samples are tested at specific temperatures, relative humidity depending on the climatic zone. During this time, the active ingredients in pharmaceuticals are routinely analyzed while they remain in the Humidity Chamber (Condition Chamber). Depending on the specific sample properties, a Long-term test can take up to several years.
>> On-going stability testing: This method is used to check if the quality of a product can be maintained even after its expiration date. The GMP standard requires continuous analysis of products already on the market to ensure that the quality of pharmaceutical products will not deteriorate once they are on the market.
>> Accelerated shelf-life testing: these tests simulate real-time aging of the drug at shorter times. In rapid aging tests, samples will tend to be exposed to higher temperatures. For example, by using this method a state can be attained within 6 weeks, if under normal conditions it could take 1 to several years.
>> Stress tests: Stress tests under extreme conditions, e.g. at 60 ° C and 60% RH, are usually conducted at an early stage of research to decide which test method is best suited for the active part mentioned. Stress testing is clearly defined in the ICH Q1A guidelines.
