FAQ'S
A Photostability Chamber is a specialized environmental chamber that simulates UV and visible light exposure to test the photostability of pharmaceutical formulations, food products, cosmetics, and packaging materials. It helps manufacturers assess stability and shelf life under light conditions.
Kesar Control's Photostability Chambers are designed and built as per ICH Q1B guidelines, which define the standard light exposure requirements for pharmaceutical photostability testing.
The chambers are equipped with both Cool White Fluorescent (CWF) and Near UV lamps to simultaneously expose samples to visible light (≥1.2 million lux hours) and UV light (≥200 Wh/m²) as per ICH Q1B requirements.
Yes. The chambers maintain controlled temperature conditions during light exposure to prevent heat-induced degradation from interfering with photostability test results.
Drug formulations (tablets, capsules, liquids, injectables), APIs, cosmetic products, food items, and primary/secondary packaging materials are commonly tested for light-induced degradation.
Yes. Kesar Control's Photostability Chambers allow the placement of dark (foil-wrapped) control samples alongside exposed samples within the same test run, as required by ICH Q1B guidelines.
Yes. The chamber is built in compliance with GMP requirements and comes with data logging, audit trails, and validation support documentation for regulatory submissions.
The chambers use calibrated lux meters and UV radiometers for real-time monitoring and automatic cutoff once the required light dose is achieved, ensuring repeatable and compliant testing.
Yes. The chamber includes advanced data logging features with USB/Ethernet connectivity, audit trails and supports IQ, OQ, and PQ validation documentation to meet regulatory and compliance requirements.
Kesar Control offers Photostability Chambers in multiple capacities and customizable configurations to suit laboratory-scale research, pilot studies, and large-scale industrial testing requirements.
Yes. Our photostability chambers support ICH Q1B testing for both drug substances and drug products including tablets, capsules, injectables, and liquid formulations. The chambers accommodate standard ICH Q1B sample arrangements and provide the specified minimum illuminance and UV exposure required for both forced degradation and confirmatory photostability studies.
