Photostability Chamber





Photostability Chamber With Temp. Control

The Osworld Photostability Chamber is designed specifically to meet ICH and FDA requirements for Photo Stability Testing. Calibrated photon detectors measure lamp intensity on the product shelf. Lamp intensity (W/m² or Lux) and exposure level (W-hr/m² or Lux-hr) are conveniently displayed at eye level by a calibrated digital light meter. After a programmed exposureo level is reached, the lamps automatically shut off. To enhance reliability, internal air temperature conditions are controlled throughout the photo stability test.

Calibration / Validation

i) Calibration
• Temperature sensor probe calibration with traceability to ERTL
• Temperature controller calibration with traceability to ERTL

ii) Validation
• IQ, OQ and PQ documentation and protocols shall be provided with equipment.
• Documentation prepared / developed for Osworld by Premier Validation Ltd. – Ireland, one of Europe’s
   leading validation consultants
• Performance Qualification with Temperature Mapping on site. The Performance Validation Test consists of one cycle at any
   one temperature point for an 8-hour period. Data is collected in printed format from up to six different points within the chamber.
   Temperature uniformity is considered acceptable if the deviation is less than ±1°C of set temperature.
