? Pressure steam sterilization.
?
A method that utilizes a certain amount of pressure and time to achieve sterilization. It is one of the most effective thermal disinfection sterilization method, which can kill all microorganisms, including bacterial spores, and is used for metal instruments, cloth, enamel and other items that are resistant to high temperatures and humidity, and the pressure and time required for different items are different. High-pressure steam sterilization, high temperature and high pressure sterilization, not only can kill general bacteria, fungi and other microorganisms, germ cells, spores also have a killing effect, is the most reliable, most commonly used physical sterilization method. Mainly used for items that can withstand high temperatures, such as culture media, metal instruments, glass, enamel, dressings, rubber and some drugs sterilization. High-pressure steam sterilizer types and styles, such as: ① under the exhaust pressure steam sterilizer is commonly used sterilization equipment, the pressure rises to 103.4kPa (1.05kg/cm2), the temperature reaches 121.3 ° C, maintained for 15 ~ 30 minutes, can achieve sterilization. ② Pulsating vacuum pressure steam sterilizer has become the most advanced sterilization equipment. Sterilization conditions require: steam pressure 205.8kPa (2.1kg/cm2), the temperature reaches 132 ° C and maintained for 10 minutes, you can kill all microorganisms, including buds, spores, including the tenacious resistance.
