Photo Stability Chamber is specially designed to be performed near the UV and with visual fluorescence, option 2 with fluorescent lamps per ICH Q1B guidelines. This unit controls the state of light and temperature through an easy-to-use color touch-screen interface. Uniform Light Distribution and High Intensity levels give instant feedback for forced degradation testing and confirmatory studies. Confirmation studies should identify essential precautionary measures in manufacturing the product, and if light-resistant packaging is required.
At the end of the exposure period, the samples should be examined for any changes and assay degradation in physical properties (such as appearance, clarity, or color of solution).
