ESL - Reach-in Photostability Chambers
Our photostability reach-in chambers are ideal for stress testing the effect of ultraviolet (UV) and cool white (CW) light on consumer goods, packaging, and pharmaceutical products.
Each Photostability Chamber features a cutting-edge, customized lighting system with fluorescent lamps strategically placed for uniform light distribution. Intensity within units is easily and individually controlled at each light bank with a microprocessor-based controller and a photo diode sensor for a fully automated, closed-loop system. The larger, upright floor model can even accommodate multiple studies simultaneously, thanks to adjustable lighting levels on each of its three separate product shelves.
These reach-ins are suitable for testing a wide range of products in multiple industries, including:
- Pharmaceutical
- Nutraceuticals
- Cosmetics
- Personal hygiene
- Food and beverage
Our reach-in Photostability Chambers come in two standard models. We offer an array of customizations and lighting features to help customers meet their unique testing requirements, including International Council for Harmonisation (ICH) standards.
