TEMPO  Make Photostability Chamber  for confirmatory studies, samples should be exposed to light providing an overall  illuminaon of not less than 1.2 million lux hours and an integrated near ultraviolet energy of not less than 200 watt hours / square meter to allow direct comparison to be made between drug substance & drug product.

Photostability Chamber


“Tempo” make PhotoStability Chamber are made of double walled construction with backside triple walled. Full view inner Toughened Glass door & front door with gasket & lock. Motorized blower is fitted on the back side for uniform temperature & humidity. 3” thick PUF insulation to ensure stable temperature with humidity. Mounted on Fiber/PU wheels for easy movement.

50 mm validation port hole with silicon rubber seal to insert sensors for validation.  Full view observation Acrylic door with gasket to observe sample inside the chamber.

Technical Specification

Controlling System

Two separate imported microprocessor based auto tune PID controller with CE mark & dual display of set value & process value for temperature & humidity with direct %RH.

Air Circulation

Motorized blower at back side of the chamber develops unique air flow system which ensures max. uniform temperature & humidity condition inside the chamber.

Heating System

High quality U shape S.S. tubular heater are used for better heating.

Humidity System

Steam injection system (Non condensing type) & reservoir tank with water level arrangement with indicator.

Refrigeration System

CFC Free hermetically sealed Emerson Copeland make compressor for better cooling with R134 A (Eco Friendly) refrigerant with time delay to safe guard compressor system.
