The Medicine Stability Test Chamber (BJPX-MS) is a precision environmental chamber designed for pharmaceutical stability studies, photostability testing, and controlled environmental research applications. This chamber provides independent control of temperature (0-65°C), humidity (40-95% RH), and illumination (up to 6000 Lux) with high accuracy and stability specifications required for ICH stability protocols and research investigations.
The system features a CFC-free R134a refrigeration system with precise temperature control (±0.5°C fluctuation) and humidity regulation (±3% RH fluctuation). The integrated single-side illumination system provides adjustable light exposure from five intensity levels, supporting photostability studies and circadian rhythm research. A 30-step programmable timer allows complex environmental cycling protocols for extended stability assessments.
How It Works
The stability chamber operates through independent environmental control systems that maintain precise temperature, humidity, and illumination conditions. Temperature regulation is achieved via a CFC-free R134a refrigeration system combined with heating elements, providing uniform temperature distribution throughout the 248L chamber volume. A PID control algorithm maintains temperature within ±0.5°C of the setpoint with 0.1°C display resolution.
Humidity control utilizes an integrated humidification/dehumidification system that maintains relative humidity between 40-95% RH with ±3% RH stability. The single-side illumination system employs adjustable light sources providing up to 6000 Lux intensity across five selectable levels, enabling photostability testing protocols. The LCD display interface allows programming of complex environmental profiles using up to 30 sequential steps, with individual step durations up to 99 hours.

Practical Tips
Verify temperature and humidity accuracy quarterly using NIST-traceable reference instruments at multiple setpoints.
Why: Maintains measurement traceability required for regulatory submissions and quality assurance.
Clean chamber interior monthly with appropriate disinfectants and inspect door seals for proper closure.
Why: Prevents contamination and maintains environmental integrity during extended test periods.
Allow chamber to stabilize for at least 30 minutes after loading samples before initiating protocols.
Why: Ensures uniform environmental conditions are established throughout the chamber volume.
Position samples to allow adequate air circulation and avoid blocking chamber ventilation pathways.
Why: Prevents thermal gradients and ensures uniform environmental exposure to all specimens.
Document chamber loading patterns and sample positions for each study protocol.
Why: Enables correlation of environmental exposure with sample position for data interpretation.
If humidity control becomes unstable, check for water reservoir levels and clean humidity sensors.
Why: Humidity system requires periodic maintenance to maintain specified performance levels.
Ensure adequate ventilation clearance around chamber and avoid blocking air intake/exhaust ports.
Why: Proper ventilation prevents overheating and maintains optimal refrigeration system performance.
