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.
