Drug Stability Test Chamber

The YJP series Pharmaceutical Stability Test Chambers are mainly used by pharmaceutical enterprises for drug aging, acceleration and other tests. They 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 tests of wood and building materials. They are ideal equipment, especially applicable to fields such as bioengineering, medical research, agricultural science, aquatic products and animal husbandry, serving as constant temperature and humidity experimental culture devices for production and scientific research. Adopting microcomputer technology and programmable control mode, by setting multiple parameters including temperature, humidity, light and time, it operates in day/night cycles to simulate natural climate. It has excellent control performance and anti-interference ability, meeting the needs of relevant tests for different drugs, as well as the production of animals and plants and the preservation of various organisms. 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 day and night respectively. It has a power failure memory function, intelligent constant temperature control system, fast response and high temperature control accuracy. The internal dehumidification method ensures good performance, convenience and reliability. The duct-type ventilation makes the air velocity in the chamber gentle, and the temperature and humidity are uniform.
