Photostability chambers are specifically designed to perform near UV and visual light testing with fluorescent lamps per ICH Q1B Guidelines, Option 2. This unit controls light and temperature conditions through an easy-to-use color touch-screen interface. Uniform light distribution and high intensity levels allow quick response for forced degradation testing and confirmatory studies. The confirmatory studies should identify precautionary measures needed in manufacturing or in formulation of the product, and if light resistant packaging is needed.
