Stability chambers meet ICH guidelines with precise temperature and humidity control

These stability chambers provide precise control over a wide range of temperature and humidity settings. They are ideal for drug stability studies, shelf-life testing for packaged products, and insect hatching and other large-scale biological research.

Key features

Temperature
Control range of 0°C to 60°C (32°F to 140°F) in 0.1°C increments.

 

Humidity
Control range of above ambient to 95% @ 37°C (98.6°F)

 

Extensive cabinet options
Doors, shelves, access ports, sockets, shelving, chart recorders and shaker systems.

Extensive humidity system options
Designed to accommodate labs with a variety of water access and drainage needs.

 

Achieves regulatory compliance
Meets International Conference on Harmonization (ICH) guidelines for drug substance and product storage testing.

Controlling relative humidity

This chart illustrates the maximum and minimum attainable humidity within the cabinet at a given set temperature under the following nominal conditions: refrigeration on, defrost off, no wet bulb recorder, no air exchange, set for 22.2°C (72°F) and 50% RH ambient. Optional heatless dryer is available for lower humidity levels.
