Stability Chamber

"VS511" Series are Stability Chambers designed and manufactured in accordance with ICH guidelines for stability testing. They have a superior accuracy and uniformity of temperature and humidity. Used for Conditioning of samples, Accelerated shelf life studies, Stability testing for drugs and pharma industries, Climate conditioning, etc.

It works on CFC free refrigerant and hermetically sealed compressor. Digitally controlled evaporative humidifier, RH Microcontroller with PID algorithm and advanced RH sensor gives precise humid conditions inside the chamber. Steam injection system has a stainless steel boiler and reservoir.
It has a clear view glass inner door. Motorised blower develops air recirculation system which ensures uniform temperature and humidity inside the chamber. Poly-Urethane is used for efficient insulation.
