Stability Chamber
Stability Chamber
Model: NSW-178

The purpose of stability testing is to provide evidence on how the quality of a drug substance or drug product varies with time under the influence of a variety of environmental factors such as temperature, humidity, and light, and to establish a re – test period for the drug substance or product under recommended storage conditions. Hence, Pharmaceutical Stability Chamber serves as an important quality attribute for the product.
