Photostability Chamber
ICH Q1B Photostability Testing Chamber for Pharmaceutical & R&D Applications
A Photostability Chamber is designed to evaluate how pharmaceutical products, drug substances, formulations, cosmetics, nutraceuticals and other light-sensitive materials respond to controlled exposure to visible light and UV light. It provides controlled temperature, humidity and light conditions to simulate defined environmental exposure and assess changes in the product over time.
It is primarily used for ICH Q1B photostability studies, helping laboratories determine the effect of light exposure on product quality, stability and performance.
