FAQ'S
A photostability chamber exposes pharmaceutical products, cosmetics, and packaging materials to controlled UV and visible (LUX) light alongside regulated temperature and humidity, to test how light exposure affects stability. ICH Q1B is the international guideline setting the minimum light-exposure thresholds (1.2 million lux hours, 200 Wh/m² near-UV) these studies must meet.
A standard stability chamber controls temperature and humidity only, under ICH Q1A(R2). A photostability chamber adds a third controlled variable, UV and visible light exposure, under ICH Q1B, specifically to test how light exposure degrades a formulation.
Yes. Kesar Control supplies photostability chambers built to ICH Q1B light-exposure specifications (1.2 million lux hours, 200 Wh/m² near-UV) to pharmaceutical and cosmetics manufacturers in Ahmedabad.
Verify the chamber meets ICH Q1B's minimum light-exposure thresholds, check that temperature and humidity are controlled simultaneously with light exposure, confirm a UV-protected viewing door, and check whether the UV/LUX meters are covered by the manufacturer's own calibration lab rather than a separate vendor serving Ahmedabad.
Photostability chambers are available in 227, 325, and 400 litre capacities, sized to fit R&D and QC lab space for pharmaceutical and cosmetics testing facilities in Ahmedabad.
Yes. The chambers deliver ICH Q1B-compliant UV and LUX exposure with PLC-based monitoring and optional 21 CFR Part 11 software, generating the documented light-exposure data manufacturers in Ahmedabad need for CDSCO drug approval submissions.
Yes. Every photostability chamber Kesar Control supplies, including units in Ahmedabad, has a UV-protected viewing door for safe mid-study inspection without opening the chamber or interrupting the exposure cycle.
Yes. Kesar Control's NABL-accredited calibration lab covers UV and LUX meter readings alongside temperature and humidity calibration, giving QC teams in Ahmedabad a single traceable certificate for the full test system.
