An autoclave is a high-pressure container that uses a pressure higher than normal pressure to raise the boiling point of water to a high temperature above 100 °C, and sterilizes liquids or appliances. It is suitable for medical and health services, scientific research, agriculture and other units.

In general, the lower the sterilization temperature, the longer the sterilization time required by high pressure steam sterilizer, instead, the higher the sterilization temperature, the shorter the sterilization time required by the autoclave. However, the time of pressure steam sterilization should be counted from the time when the autoclave chamber reaches the required sterilization temperature and until the sterilization is completed.

The total time of portable autoclave sterilizer includes: thermal penetration time, that is, the time required from reaching the sterilization temperature in the sterilization chamber to the time when the center of the sterilized item also reaches the sterilization temperature. The time length depends on the nature of the items to be sterilized, the package size, the placement location and the degree of air evacuation in the autoclave and the type of sterilizer. Sterilization maintenance time, that is, the time required to kill microorganisms, is generally expressed by the time required to kill Thermobacter stearothermophilus spores. The safety time is generally half of the maintenance time, and its length depends on the disinfection items. Sterilization of thermally conductive metal equipment does not require a safe time.

Steam autoclave sterilizer has the advantages of fast sterilization speed, reliable effect, high temperature and strong penetrating power. It is an ideal equipment for disinfection and sterilization of medical equipment, dressings, glassware, solution culture medium, etc.
