Photo Stability Chambers


Labtop PhotoStability Test Chambers are especially designed to conduct stability and shelf life studies on drug and drugs substances. These Chambers are designed to provide high intensity lighting system to comply with ICH guide lines for photo stability conditions with white fluorescent exposure of 1.2 million LUX hours and ultra violet energy exposure of 200 W hours/sq. meters. LABTOP chambers conform to International Standards such as ICH, WHO Guideline, and USFDA requirements. Printer interface for LUX & UV meter, automatic shut off after specified exposure level.


The cabinet of Labtop Chambers is insulated with high density CFC free Poly Urethane Foam. Interior of chambers is mirror finish stainless Steel (304 SS, 0.8 mm thick). The exterior is white powder coated (1.0 mm thick) mild steel and the door has magnetic gasket with a keyed door lock. Stainless steel trays are provided for storage inside. The cooling is effected by hermetically sealed compressor of high quality. GMP models are in total stainless steel (Inside S. S 304 with mirror finish and outside. S 304 dull finish and inner 316 is also available on request.)


The cooling is effected by CFC free refrigeration system with a condensing unit located inside the chamber. Labtop condensing units are characterised by high-efficiency heat transfer and low power consumption.
  • CFC free refrigeration with time delay to safe guard the compressor.
  • Inner grooved copper tubes and slit aluminum fins for superior heat transfer.
  • Filter drier for moisture and dirt protection.
  • Safety and control devices for better system protection.
  • Thermally protected and permanently lubricated fan motors.
