Thermolab Scientific Chambers are perfectly 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. Thermolab 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 Thermolab Scientific Chamber repeatedly produces required conditions, structural integrity that keeps the chamber working properly through years of demanding test cycles and measuring equipment’s that precisely records all test data.

Thermolab Stability testing chambers are designed to meet, if not exceed, stringent quality standards recognized internationally. Offering all temperature and relative humidity conditions specified in ICH guidelines as below:

25°C/ 60% RH       30°C/ 65% RH       30°C/ 70% RH

30°C/ 75% RH       40°C/ 75% RH       25°C/ 40% RH       

30°C/ 35% RH         40°C/ NMT 25% RH


Today, other than Pharma and Bio-pharma products, stability studies are required for Alternate medicines, Food & Beverages, Medical devices, Cosmetics and other items to check the environmental effects on the product.

Man, Machine, Product and Environmental Safety

  • Safety system to cut off the power supply in case of overshoot and undershoot of Temperature and Humidity conditions giving audio visual alarms.
  • Additional safety thermostat to cut off the power supply in case of temperature overshoots.
  • Low water level alarm for humidity system.
  • Emergency push button inside the chamber to de-energise magnetic lock.
  • Panic switch inside the chamber with audible alarm outside.
  • Manual unlocking mechanism for door from inside the walk-in chamber.
  • Environment friendly processes and refrigerants used.

Hydronic Cooling System

  • Thermolab has innovated a unique chilled water circulation system which reduces the electrical consumption by 60% and water consumption by 90%.
  • Factory assembled refrigeration system, avoiding on-site piping work.
  • This unique design enables maintenance of optimum cooling coil temperatures depending on the chamber conditions and resultant Dew Point.
  • The life of compressor increases as the running time of compressor has enormously decreased.
  • Compact plug and play design and can be placed behind the chamber or in the technical area.
