Pressure steam sterilizer is sterilized by high temperature and high pressure, which can not only kill general bacteria, fungi and other microorganisms, but also kill spores and spores. It is the most reliable and widely used physical sterilization method.

The principle of pressure steam sterilizer is to use high-temperature saturated water steam to denature the protein of microorganisms and cause the death of microorganisms within a certain period of time, so as to achieve the purpose of sterilizing moisture-resistant and heat-resistant articles.

The principle of temperature rise is that steam cannot escape in a closed steamer, and the boiling point of water will continue to increase as the pressure continues to rise, so the temperature in the pot will also increase, and the temperature in the pot can reach 121°C under 0.1MPa pressure. . All kinds of bacteria can be killed quickly at this steam temperature.
