We are the leading Original Manufacturers of Vertical Autoclaves in Delhi (India) having core team with an Industry experience of over 25 years.

Our Triple Walled Autoclaves (Vertical) are for most suitable for Dry sterilization cycle requirement in labs. Triple walled vertical autoclaves incorporated with steam jacket are widely used for day to day sterilization procedures and in various laboratory application where dryness of the sterilized medium is of utmost importance. Highly useful for meeting sterilizing needs of Scientific Research Institutions, Hospitals, Pharmaceutical Laboratories, Tissue culture Labs, Mushroom Centers, Bio-fertilizer Laboratories and Institutes requiring sterilization of culture media, glassware, Dressing material, utensils, surgical instruments, Lab ware etc. in steam under pressure or places with modest sterilizing requirements & thereby controlling the spread of infections caused by various pathogenic micro-organisms.

  • Automatic Low Water Level Cut-off Device. (For protection of Heaters)  This device is a safety device for the protection of heaters. This device ensures that the heater automatically switches “off” in case the desired water level fall below the prescribed level & thereby protects it from burning.
  • Digital Temperature Indicator. This device indicates the temperature inside the chamber.
  • Digital Timer with Alarm System(optional). This is a semi-automatic device which is initiated once the pressure level inside the chamber reaches the desired value, it regulates the sterilization time of the media to be sterilized and when the desired time is passed, it activates the buzzer, which indicates that the sterilization cycle is complete and media can be extracted
  • Silicon Rubber gasket
  • Temperature Chart Recorder. This a semi automatic self contained easy to use recording device, which permanently records the temperature is any given sterilization cycle on a graph sheet.
  • Microprocessor based Digital Temperature controller Cum Indicator
  • PLC Control System


  • Above mentioned sizes are of standard Autoclave series. However, we are capable to manufacture/fabricate any special size as per customer’s exact requirement.


  • Following company’s constant endeavor to improve design & quality, the   instrument may differ in detail, description or as exhibited in this manual.
