Environmental Spacialties' 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 chamber has a cutting-edge, tailored lighting system, with fluorescent bulbs strategically arranged for even light distribution. Each light bank’s intensity may be easily and independently regulated using a microprocessor-based controller and a photo diode sensor to create a fully automated, closed-loop system.
The larger, upright floor model can even support many studies simultaneously, thanks to adjustable lighting settings on its three distinct product shelves.
These reach-ins are appropriate for testing a variety of items in many industries, including:
- Personal hygiene
- Food and beverage
- Pharmaceutical
- Nutraceuticals
- Cosmetics
Versatile photostability chamber design
Environmental Specialties’ reach-in photostability chambers come in two typical configurations. They provide a variety of adaptations and illumination options to help companies fulfill their specific testing needs, including the International Council for Harmonisation (ICH) standards.
