Photostability chambers
Photostability chambers
- Independent control of near UV and cool white VIS lamps to prevent overexposure and allow flexibility in testing.
- Automatic and manual modes for test duration control.
- Dimmable lamps for specific light intensity testing (230V models).
- Programmable alarms for lamp replacement notifications.
- Specular aluminum reflective surfaces for uniform light distribution.
- Stainless steel interior for easy maintenance.
- Two light detectors with integral radiometer for precise light intensity measurements, calibrated to NIST standards.
- Precise temperature control via PID controller.
- Humidity control in specific models to isolate hydration effects during testing.
- UVA and VIS lamp types are fluorescent, with typical UVA light intensity ranging from 2-30 W/m2 and VIS light intensity from 2-35 klux.
- Temperature range is 10°C to 35°C with lights on, and humidity range is 40-70% RH for specific models.
- Interior construction includes reflective specular aluminum and stainless steel, with a total internal volume of 10.5 cu. ft.
- Electrical requirements vary by model, with options for 115V, 208/230V, and 230V configurations.

PHOTOSTABILITY CHAMBERS The 6540 Series Photostability Chambers were specifically designed to perform near UV and visual light testing with fluorescent lamps per ICH Q1B Guidelines, Option 2. This second generation bench-top unit controls light and temperature conditions through an easy-to-use color touch-screen interface. Lights automatically shut off after a specified exposure level or time duration. Uniform light distribution and high intensity levels allow quick response for forced degradation testing and confirmatory studies. Precise humidity control (Models 6545-1, 6545-2 and 6545-3) is...

STANDARD FEATURES CONTINUED • Shelves slide-out for quick and easy loading and unloading of samples. • Strategic lamp spacing provides enhanced light uniformity. Overhead lighting results in a large illumination area for maximized direct lighting. • Door safety switch turns lights off when the door is opened. The lockable door prevents accidental disturbance of in-process tests. • Two access ports (one per shelf) are standard. MAIN SCREEN DISPLAY • Performance is managed through an eye level, icon-based, color, touch-screen interface for user convenience. • The easy-to-use controls Active display...
