The Heratherm 250L stability chamber provides precise control of temperature and humidity. It is designed for stability and shelf-life testing applications. Peltier technology ensures efficient and quiet operation. Integrated data logging supports regulated laboratory environments.
The Thermo Scientific Heratherm 250L stability chamber is designed for controlled environments with both temperature and humidity regulation. This model is suitable for stability testing, shelf-life studies, and ICH Q1A applications. The combination of temperature and relative humidity control enables reproducible and consistent test conditions.
The temperature range spans from 0 to 70 °C, while relative humidity ranges from 10% to 90%. Both parameters can be adjusted in fine increments of 0.1. This makes the chamber suitable for a wide range of pharmaceutical and industrial testing protocols.
The stability chamber features an intuitive touchscreen interface for full process control. Users can program temperature and humidity profiles, including ramps and cycles. Data logging supports compliance with 21 CFR Part 11, with export options via USB or cloud connectivity.
User access can be restricted through account management and password protection. Alarm functions provide immediate notification of deviations. This ensures reliable documentation and process security.
The 250L model offers a compact benchtop design suitable for laboratories with limited space. Installation is straightforward and does not require specialized setup. Peltier technology enables energy-efficient heating and cooling without a compressor.
The integrated humidity system minimizes water consumption while maintaining precise control. Two access ports allow the use of external sensors or cables. The rounded interior and removable shelving simplify cleaning and reduce contamination risks.
