Premier Electrosystems' Environmental Chambers are designed for the high requirements of stability studies and climatic tests. With Stability Chambers specifically developed to meet FDA/ ICH stability requirements generating exceptional control and uniformity of both temperature and humidity. Premier's Stability Chambers feature various safety feature, audio visual alarms, 21 CFR part 11 software and a vast range of options and is the most preferred choice for stability studies. Every Chamber is made in a rigid panel type construction that keeps the chamber working properly through years of demanding test cycles. We also provide instruments that precisely record all test data.


Premier's Stability Chamber are made of double-walled construction with triple backside. Full view inner acrylic door & front door with gasket & lock. Motorized blower is fitted on the backside for uniform temperature & humidity. 3" thick PUF insulation to ensure stable temperature with humidity. The unit is provided with adjustable stainless steel rod mesh tray. The equipment is mounted on caster wheels for easy movement.
