LAB1ST Pharmaceutical Stability Test Chambers are designed to deliver precise, reliable, and compliant stability testing environments for pharmaceuticals.
With temperature control from 0°C to 65°C and humidity control from 25% to 95% RH, these chambers support long-term, accelerated, and strong light exposure testing in accordance with ICH guidelines.
Built with energy-efficient systems and advanced control technology, they are ideal for pharmaceutical labs and R&D facilities worldwide.
Features
-
Eco-Friendly Refrigeration: Utilizing a fluorine-free design for high efficiency, low energy consumption, and reduced environmental impact.
-
Uniform Airflow System: An engineered air duct ensures consistent temperature and humidity distribution, while a standard 25mm test port facilitates easy external monitoring.
-
Dual Compressor Redundancy: Two automatic-switching compressors from leading international brands provide uninterrupted operation for long-term stability studies.
-
Multi-Level Safety Protection: Comprehensive safeguards include independent temperature limit alarms, compressor and fan overheat protection, over-pressure, overload, and water shortage alerts.
