Environmental Rooms

Since 1972, Russells has utilized our expertise in refrigeration and air conditioning technologies to manufacture environmental rooms that can maintain -40° F cold on a continuous basis or can reach as high as 185° F heat. These simulation test systems can be supplied with temperature and humidity PID controls or with computerized data acquisition and control systems. They allow customers to undertake testing for long-term stability, accelerated testing, humidity, comparative stability, forced long-term stability and stability of active pharmaceutical ingredients. Our environmental rooms are designed to meet FDA and ICH guidelines for stability testing and storage.

About Environmental Humidity and Stability Rooms

We use the highest quality components in fabrication to ensure that our environmental rooms continue at top performance for many years. Our test rooms may be used for the following applications:

  • Biological/biotechnology Research
  • Pharmaceutical stability
  • Shelf life experiments in the food industry
  • Entomology (insect rearing) research
  • Industrial environmental testing
  • Crop science
  • Soil science
  • Laboratory/Medical
  • Electronic burn-in
  • Seed storage
  • Plant growth
  • Consumer product testing
  • Archival storage
  • Cold storage
