Drug Stability Test Chamber

The YJP series Pharmaceutical Stability Test Chambers are mainly used by pharmaceutical enterprises for testing drug aging and accelerated stability, and are also suitable for cell and tissue culture, seed germination, seedling cultivation, insect and small animal rearing, microbial and antibiotic culture and preservation, as well as performance testing of wood and building materials. They are ideal devices, especially applicable as constant temperature and humidity experimental culture equipment for production and scientific research in fields such as bioengineering, medical research, agricultural science, aquatic products, and animal husbandry. Adopting microcomputer technology with programmable control mode, by setting multiple parameters including temperature, humidity, light, and time, it can operate in day/night cycles to simulate natural climate, with excellent control performance and anti-interference ability, meeting the requirements of various drug-related tests, animal and plant production, and various biological preservation needs. With fully automatic microcomputer control and touch switches, it is easy to operate. The programmable control mode allows separate setting of temperature, humidity (adjustable), light, and time for both day and night. It has a power failure memory function, an intelligent constant temperature control system with fast response and high temperature control accuracy, and adopts an internal dehumidification method for reliable performance. The duct-type ventilation provides a gentle air flow in the chamber, ensuring uniform temperature and humidity.
