Purification testing chamberIt is a professional equipment used to simulate real indoor environments and quantitatively evaluate the purification performance of air purification equipment and materials. It is widely used in the performance testing and certification of air purifiers, fresh air systems, disinfection equipment, and decoration materials. Usually composed of cabin, air purification and temperature and humidity control system, air sampling system, pollution source generation device, etc. The cabin is made of 304 stainless steel or glass material to reduce the adsorption of pollutants; Equipped with a high-precision sensor network, it can monitor the concentration changes of pollutants such as PM2.5, formaldehyde, TVOC in real time, with a detection accuracy of 0.001mg/m ³. Its temperature and humidity control range is wide (temperature 10-35 ℃, humidity 0-99% RH), and the control accuracy is high (temperature ± 0.1 ℃, humidity ± 1% RH), ensuring the accuracy of test results.
Purification testing chamberScope of application:
1、 Environmental simulation and material testing
Material aging test
Application: Simulate the durability of materials in extreme environments such as high temperature and humidity, corrosive gases, ultraviolet radiation, etc.
Example: Automotive interior materials undergo VOC (volatile organic compound) emission testing in a purification chamber to evaluate their environmental performance.
Particulate matter and pollution control
Application: Test the performance of protective equipment such as air filters, masks, and clean clothing.
Example: Testing the interception efficiency of HEPA filters in a controllable cleanliness environment, or simulating the filtering effect of masks in a hazy environment.
2、 Biological and Medical Fields
Aseptic product testing
Application: Conduct sterile tests on medical devices and drug packaging in a sterile purification chamber to ensure no microbial contamination.
Example: Verify the cleanliness of the filling line in the purification chamber before injection production to ensure compliance with GMP standards.
Cell and Microbial Culture
Application: Provide a dust-free and sterile environment for cell culture and gene experiments, avoiding interference from miscellaneous bacteria.
Example: Stem cell research needs to be conducted in an ISO Class 5 cleanroom to prevent contamination from causing experimental failure.
3、 Electronics and Precision Manufacturing
Semiconductor and chip manufacturing
Application: Simulate a clean environment in a chip production workshop to test the compatibility of materials or equipment.
Example: Detecting surface defects on wafers in a purification chamber, or verifying the uniformity of photoresist under dust-free conditions.
Precision instrument calibration
Application: Provide a dust-free environment for precision equipment such as optical microscopes and mass spectrometers to ensure calibration accuracy.
Example: Calibration of laser particle size analyzer in a purification chamber to avoid dust interference with measurement results.
4、 Chemical and Environmental Research
Study on Chemical Reaction Dynamics
Application: Study gas-solid phase catalytic reactions or pollutant degradation processes in an environment without impurity interference.
Example: Simulate the catalytic conversion reaction of automobile exhaust in the purification chamber and analyze the efficiency of the catalyst.
Environmental pollutant monitoring
Application: Test the release of harmful substances (such as formaldehyde and benzene derivatives) from materials or products under specific conditions.
Example: Furniture boards undergo VOC emission testing in a purification chamber to evaluate their environmental protection level.
