Precision Photostability Testing for Laboratories

Our Photostability Chamber is designed to provide controlled light exposure for stability testing of pharmaceutical products, formulations, and packaging materials. It helps evaluate the effect of visible and ultraviolet light under defined environmental conditions.

The chamber offers precise control of temperature, illumination, and testing duration to support consistent and repeatable results. Its user-friendly operation and reliable performance make it suitable for quality control, research, and stability study applications. Built for dependable laboratory use, the Photostability Chamber supports structured testing procedures and helps laboratories maintain accurate records, product quality evaluation.

CONSTRUCTION

Double wall, Outer cabinet mild steel powder coated or stainless steel 304 and Inner Chamber Stainless Steel 304
Full view glass door a multi pane viewing door prevents condensation & allows product view. Inner & outer doors are sealed around the entire perimeter by silicone sponge rubber gasket.
The chamber is insulated by filling PUF in the space between outer body and chamber to prevent temperature loss.
Chamber illumination: Florescent light with door switch.
Castor wheels for easy move ability.
Shelves : Stainless steel.
UV & Fluorescent Lights
As per ICH Guidelines-1.2 Million Lux hours of visible light and 200 watt Hr/m² of UV light. Auto Shut OFF after specify exposure time.
Individual switch is provided to ON/OFF for UV& Fluorescent light.
UV light is switched off automatically once inner glass door is opened to prevent hazardous exposure.
Samples can be tested under Fluorescent light or U.V. lights separately
