The 6540 Series Photostability Chambers were specifically designed to perform near UV and visual
light testing with fluorescent lamps. 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 achieved through ultrasonic injection and
mechanical refrigeration methods.
- Independent control of near UV and cool white VIS lamps are
- provided to eliminate overexposure for confirmatory tests
- and provide flexibility for forced degradation studies.
- In “Automatic” mode, lights turn off at the end of a programmed
- exposure or timed test.
- “Manual” mode allows a flexible test time duration and makes
- validating the chamber easy.
- Dimmable lamps (230V models) allow testing at specific light
- intensity levels.
- Programmable alarms notify the user when aging lamps
- should be replaced.
- Specular aluminum reflective surfaces provide uniform UVA & VIS
- light reflection and maintain proper SPD (spectral power distribution).
- Stainless steel interior construction provides a smooth, non-porous
- surface for easy maintenance.
- Two light detectors (one VIS and one UVA) with an integral radiometer are
- standard and provide precise and accurate light intensity measurements.
- Light detectors are both cosine corrected and calibrated to NIST traceable standards.
- Precise temperature control is provided through use of a PID controller.
- Humidity controlled units (Models 6545-1, 6545-2 & 6545-3) isolate the effects of
- hydration during photostability testing.
- 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.
