The pressure steam sterilizer is a rapid and reliable disinfection and sterilization equipment using saturated pressure steam. It can sterilize medical equipment, dressings, glassware, solution culture medium, etc., and is recognized as one of the most reliable sterilization technologies in the world. Pressure steam sterilizer has a very long history, with a history of more than 100 years. It is often used in food processing enterprises, hospitals at all levels, disease prevention and control centers, inspection and quarantine institutions and other enterprises and institutions, and is widely used.

The most basic working principle of the pressure steam sterilizer is to thoroughly sterilize the bacterial material through the steam under high temperature and high pressure and the large amount of latent heat it releases. When the generated steam is in full contact with the bacteria-bearing items, it can condense into water and release a large amount of latent heat, so that the temperature can be raised rapidly, and finally the purpose of sterilization and the acceleration of the sterilization effect can be achieved. Some mixed gases in the pressure steam sterilizer are mainly closely related to the actual temperature and force. The relevant experimental research results fully prove that only when the actual temperature and pressure of the mixed gas existing in the pressure steam sterilizer reach an optimal value at the same time, the actual effect of the sterilization can reach the optimal level.
