The medicine stability chamber employs an advanced temperature and humidity control system along with a light simulation device to create an ideal environment for drug stability research. The outer shell is made of materials with excellent thermal insulation properties, and the interior uses a stainless - steel inner liner, which not only ensures good thermal insulation but also facilitates cleaning and disinfection. Its core advantage lies in its ability to precisely simulate various environmental conditions, such as different temperatures, humidities, and light intensities, with extremely high control accuracy, creating a stable and repeatable experimental environment. It is equipped with multiple safety protection devices, such as over - temperature and over - humidity protection, to ensure experimental safety. It is widely used in the R & D and production processes of pharmaceutical enterprises as well as drug quality testing institutions. By examining the stability of drugs under different environmental conditions, it provides reliable data for drug quality evaluation and expiration date determination, ensuring the stable quality of marketed drugs.
