Frequently Asked Questions
1: What kind of sample loading pattern is recommended for uniform light exposure?
To ensure uniform illumination and airflow, samples should be distributed symmetrically on the adjustable stainless-steel shelves, avoiding shadow zones. The chamber’s JAKEL fan-assisted air circulation ensures even temperature and light exposure across all test levels.
2: What alarm systems are built into the unit to protect test integrity?
Pharmaceutical Light Stability Chamber BZML-511 includes audible and visual alarms for deviations in temperature, humidity, and light levels, as well as a temperature-limiting safety cut-off that halts operation if thresholds are exceeded. Alarm history can be reviewed via the control interface.
3: How does the UV sterilization function impact testing conditions?
The UV sterilization feature is operated independently and is not active during testing unless manually triggered. It is typically used between test cycles to disinfect the chamber and prevent microbial contamination of samples or sensors.
4: What environmental conditions are required for optimal operation of the chamber?
Pharmaceutical Light Stability Chamber BZML-511 operates optimally in ambient temperatures between 5°C to 30°C, away from direct sunlight or ventilation ducts. Consistent power supply (AC 220V, 50Hz) and low ambient humidity contribute to stable performance.
5: How is uniform temperature and light distribution maintained?
Pharmaceutical Light Stability Chamber BZML-511 uses a JAKEL air circulation fan and a unique air duct structure to ensure even distribution of temperature and light throughout the interior.
6: What are Pharmaceutical Light Stability Chambers used for?
Pharmaceutical Light Stability Chambers are used to test the photostability of pharmaceutical products, packaging materials, and raw ingredients under controlled light conditions.
7: What type of lighting is used inside the chambers?
Our Pharmaceutical Light Stability Chambers use UV and visible fluorescent lamps with programmable light intensity, often ranging from 0 to 6000 Lux, to simulate daylight exposure.
8: Can temperature and humidity be controlled during testing?
Yes. Our chambers provide precise temperature and humidity control, with tight tolerances (e.g., ±0.5°C and ±3% RH), even under illuminated conditions.
9: How is light intensity monitored and controlled?
Built-in light sensors continuously monitor UV and visible light levels. The system allows step-controlled or programmable light exposure for reproducibility and compliance.
10: What safety features are included in these chambers?
Safety features include temperature-limiting alarms, UV protection shields, auto-shutdown mechanisms, and system diagnostics.
