KDSI Pharmaceuticals Drug Stability Test Chamber is a specially designed device that is used to study stability and shelf life of various medicines and drug related substances. They are also working for seed testing and testing of biological studies, mechanical and electronic equipment and find extensive use in pharmaceutical industries, biotechnology industries, food industries, pharmaceutical research and scientific research institutions. KDSI stability test chambers are able to provide a highly accurate and optimal position of temperature, humidity and light for long-term stability tests. They are suitable for long-term experiments, high temperature tests, accelerated tests as well as stability testing under bright light. The drug stability test chamber and the stability chamber have been designed according to international standards and CE certification is for safety and reliability.





  • The strong construction is made of outer chamber mild steel, which has been duly pre-treated and finished with a powder coated paint for permanent finishing.
  • The inner chamber made of stainless steel sheets (304 grades).
  • To maintain uniformity of temperature in the chamber, equipped with durable coaxial blower for forced air circulation back to triple wall.
  • The outer front double walled door is untouched and with no magnetic tape for wind tight closing without any temperature loss, which is available with lock and arrangement.
  • The SS angels are to keep the shelves in the inner chamber at convenient levels. Supplied with 2 or 3 removable shelves.
  • Enables inspection and monitoring of internal chamber samples without disturbing the temperature of a full visual internal plexi-glass door process.
  • High grade PUF INSULATION between the outer and internal chamber for minimum thermal damage.
  • ISI marked compressor / condensing units are cooled by CFC free and R-134 lies in thin air evaporator in the air circulation path by an environmentally friendly refrigerant.
  • Used by indirect heating system by the air heater made of stainless steel placed on the way of moving air in the heating chamber.
  • Temperature range. The temperature range of our stability chamber model is 20deg.C to 60deg.C.
  • LED display with PT-100 sensor (resolution 0.10C) fit with temperature accurately controlled by microprocessor-based temperature controller + 10C
  • Humidity System: Steam injection system generates humidity in which boiler tank is placed, which is placed under the chamber attached with boiler heater.
