Steam Sterilization Mechanism

Dry heat autoclave sterilization chamber to kill the most commonly used means of biological physics, because of high temperature on bacterial obvious lethal effect. Elevated temperature and solidification cell degeneration, loss of enzyme activity, allowing the bacteria to die. Heat sterilization chamber most reliable and widely used sophisticated sterilization method. Usually moist heat sterilization and dry heat sterilization methods.

Autoclave sterilization method using heat, at the same temperature, heat than dry heat sterilization effect is good, for the following reasons.

1. The solidification temperature of the protein on its moisture content, the greater the water content, the occurrence of the solidification temperature lower. Moist heat sterilization of bacterial proteins can absorb moisture, which is easier than the solidification temperature of the hot and dry in the same air.

2. Moist heat sterilization process steam release a lot of latent heat, further increasing the temperature. At the same temperature, heat than dry heat sterilization time is short.

3. Gas heat penetration than dry heat gas is strong, so the heat than dry heat effect is good. High pressure steam can kill all microorganisms, including high temperature or individual spores, fungal spores and other bacteria. Dental autoclave sterilizer sterilization temperature increases with the increase of steam pressure, by increasing the vapor pressure of the sterilizing time can be shortened. It is therefore one of the most effective and most widely used methods of sterilization.
