The high pressure steam sterilizer is the most common and most effective sterilization method in the thermal disinfection method. The advantage is that the steam has strong penetrating power and can kill all microorganisms.
Sterilization principle: The high pressure steam sterilizer is a kind of wet heat disinfection method. The principle is: in the closed steamer, the steam can not overflow, the pressure rises continuously, the boiling point of the water is continuously increased, and the temperature inside the pot is also increased. It will increase.
At a pressure of 0.1 MPa, that is, a vapor pressure of 103.4 kPa (1.05 kg/cm2), the temperature in the pot reached 121 ° C for 15 to 30 minutes. When the temperature exceeds the temperature range of the optimal physiological activity of the cells, the metabolism of the cells is slowed down, and the proteins, enzymes and nucleic acids of the cells are permanently destroyed, resulting in irreversible death of the cells. At this steam temperature, various bacteria and their highly heat-resistant spores can be quickly killed, which is the most reliable and most commonly used physical sterilization method.
The autoclave itself has a substance that does not damage the surface of the product and does not change or damage the drug, the drug solution, the glass device, the medium, etc. under high temperature and high humidity conditions, and can be autoclaved.
High pressure steam sterilizer have been widely used in various biochemical laboratories and hospitals for the extinction of some culture media, glass products, physiological saline, and the like.
There are many types and styles of current high pressure steam sterilizers, such as:
1 vented pressure steam sterilizer is a commonly used sterilization equipment, the pressure rises to 102.9kPa (1.05kg / cm2), the temperature reaches 121 ~ 126 ° C, maintained for 20 ~ 30min, can achieve sterilization purposes.
2 pulsating vacuum pressure steam sterilizer has become the most advanced sterilization equipment. Sterilization conditions require: steam pressure 205.8kPa (2.1kg / cm2), temperature above 132 ° C and maintained l0min, can kill all microorganisms including bacteria cells with stubborn resistance.
