Autoclaving refers to the use of thermal energy to kill microorganisms. The principle is that high temperature denatures proteins in the protoplasm, inactivates enzymes, and causes the death of microorganisms. High temperature sterilization mainly includes high pressure steam sterilization, dry heat sterilization and burning sterilization. If the operation is improper, the expected sterilization effect will not be achieved. Portable steam sterilizer manufacturers now analyze common errors as follows:

Steam sterilization belongs to moist heat sterilization. Due to the potential existence of moist heat sterilization, the temperature of the object to be sterilized is lower than that of steam. The steam condenses into water on its surface and releases the potential, which can quickly increase the temperature of the object to be sterilized. And because water and water vapor have larger heat capacity, faster heat conduction, and stronger penetrating power than air, sterilization requires lower temperature and shorter time than dry heat sterilization. Since the temperature of the steam in high-pressure steam sterilization increases with the increase of the pressure, the high-temperature steam for sterilization is obtained by pressurization.

Common mistakes in the operation of portable portable steam sterilizers are:

Exhaust is not complete. Before boosting the pressure, the cold air in the pot should be exhausted. Because the air is a poor thermal conductor, if it is not exhausted, the cold air will accumulate and stay in the middle and lower part of the disinfection cylinder in the sterilization pot, surrounding the objects to be sterilized. around. In this case, if half of the air is removed from the pot, when the pointer of the pressure gauge reaches 105Pa, the actual temperature in the pot can reach 112°C, which is as much as 9°C lower than the required 121°C, which will lead to incomplete sterilization and may cause Large-scale contamination.
