Stabiity Chambers

The stability chambers meet International Conference on Harmonization (ICH) guidelines for drug substance and product storage testing. The units are ideal for drug stability studies, shelf-life testing for packaged products, and insect and other large-scale biological research.

  • Chambers feature 0°C to 60°C (32°F to 140°F) temperature range that can be set in 0.1°C increments
  • Directed Airflow System distributes airflow uniformly throughout the chamber
  • Various options available to address specific needs for shelving, door, water system, documentation and more

Stability Chambers and ICH Guidelines: Choosing the Right Equipment for Pharmaceutical Stability Testing

ICH Guidelines

In the pharmaceutical industry, stability testing helps provide evidence as to how the quality of a drug will vary with time under a variety of environmental conditions including temperature, humidity, and light exposure. This testing must be completed before a drug enters the market. Learn how to choose the right Stability Chamber to meet compliance standards.
