Pressure steam sterilizer is a fast and reliable disinfection and sterilization equipment that uses saturated pressure steam to sterilize items. It can sterilize medical devices, dressings, glassware, solution culture medium, etc. It is considered one of the most reliable disinfection techniques in the world. Pressure steam sterilizer has a long history of more than 100 years, and is often used in food processing enterprises, hospitals at all levels, centers for disease prevention and control, inspection and quarantine agencies and other enterprises and institutions.

The most basic working principle of pressure steam sterilizer is to thoroughly sterilize bacterial substances through water vapor under high temperature and high pressure and the large amount of latent heat released. When the generated steam is in full contact with the items with bacteria, it can condense into water, and then release a large amount of latent heat, so that the temperature rises rapidly, and finally achieves the purpose of sterilization and accelerated sterilization. Some of the mixed gases in the pressure steam sterilizer are mainly related to the actual temperature and force. The relevant experimental research results have fully proved that only when the actual temperature and pressure of the mixed gas in the pressure steam sterilizer reach the optimal value at the same time, the actual sterilization effect can reach the optimal level.
