LHH Pharmaceutical Stability Test Chamber
High Precision Drug Stability Testing Chamber for Temperature, Humidity and Light Simulation

Product Introduction
The LHH Pharmaceutical Stability Test Chamber is a professional drug stability testing chamber designed to provide long-term stable temperature, humidity, and illumination environments for pharmaceutical stability evaluation.
It is widely used in pharmaceutical companies, medical research institutions, biotechnology laboratories, and life science industries for accelerated stability testing, long-term stability testing, high-temperature testing, and photostability testing.
The LHH series stability chamber simulates different environmental conditions according to pharmaceutical testing requirements, including 25℃/60%RH long-term stability testing, 40℃/75%RH accelerated stability testing, and strong light exposure testing. It is an ideal solution for GMP-compliant pharmaceutical quality evaluation and new drug development.

Working Principle
The LHH Pharmaceutical Stability Test Chamber creates controlled environmental conditions by precisely regulating temperature, humidity, and illumination.
The temperature control system uses BTC balanced temperature regulation technology combined with PT100 platinum resistance sensors to monitor internal temperature changes. The heating and refrigeration systems automatically adjust output to maintain stable temperature conditions.
Humidity is controlled through an external isolated boiler steam humidification system, allowing accurate moisture adjustment within the chamber.
The refrigeration system, air circulation system, and intelligent controller work together to maintain uniform environmental conditions. The programmable touchscreen controller records and executes predefined temperature and humidity curves for automated stability testing.
