Bahnson’s Photostability Chambers

Photostability tests are common in consumer goods, such as nutraceuticals, personal hygiene, cosmetics, and food & beverage, as well as pharmaceutical research laboratories since exposure to light may sometimes cause unacceptable and unexpected changes in properties. In order to perform these tests accurately, specially designed photostability chambers are used.  

These chambers are equipped with fluorescent lamps strategically located for the uniform distribution of visual or near ultra-violet light. 

At BES, our custom-designed lighting system utilizes upright floor models to provide up to three simultaneous light studies with adjustable, uniformly-controlled light levels across product shelves. Intensity within units is easily and individually controlled at each light bank with a microprocessor-based controller and a photodiode sensor to provide a fully automated, closed-loop control system.
