Description
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.
