Photostability Testing for
Cosmetics & Pharmaceuticals

PRODUCT SUMMARY  LX-5014

(ICH Guidelines & Forced Degradation)
The Q-SUN® xenon test chamber from Q-Lab offers state of the art, full-spectrum photostability test
exposures for pharmaceutical and cosmetics applications. Q-SUN testers are available in two sizes
with options that meet ICH Guidelines for Photostability Testing of New Drug Substances and Products, including simulation of direct sunlight or sunlight through window glass. Accurate control of light
intensity and temperature ensures repeatable and reproducible results. These features enable the
Q-SUN chamber to perform photostability tests according to in-vitro test procedures for sunscreens.

Simple operation and lamp replacement so you can concentrate on what’s most important:
your tests!
Full spectrum xenon arc lamp and optical filter system creates D65 and ID65 sunlight simulations
that enable you to test your products against outdoor or indoor daylight.
SOLAR EYE® Irradiance Control monitors and controls the light intensity to ensure your tests are
repeatable and reproducible.
Precise control of chamber air or black panel temperature gives you flexibility to determine the
effects of different temperature environments on photodegradation.
Optional chiller unit enables tests to be run at room temperature or as low as 15°C so you can
determine the synergistic effects of light and heat on your materials and products.

Two Sizes All the Critical Features

The Q-SUN tester comes in two sizes with all the
critical features for pharmaceutical and cosmetics
applications. The Xe-1 is available in a convenient
tabletop size and offers an optional chiller. For
labs that need high throughput, the Xe-3 is a freestanding unit with triple the capacity. The Xe-3
also provides precise control of relative humidity.
