Drug Stability Test Chamber LDST-A23

Drug Stability Test Chamber LDST-A23 designed with 800L internal capacity volume. It offers 20 to 98 % RH humidity range and temperature ranges from 0℃ to 100℃. Designed to simulate constant climatic conditions for testing a wide variety of pharmaceutical raw Drug material or finished Drug products for their quality, performance, shelf life and stability. It features conductive film located on the interior glass (of double layer 8 cm thick insulation glass) to prevent window frosting, built-in LED light for the work room lighting to clearly observe samples. A good temperature humidity chamber is essential for evaluating potential success or failure of a product in the field.
