Autoclaves Principle And Classification
Autoclaves principle and classification:
High-pressure steam sterilization (autoclaving) to kill all microorganisms, including spores , sterilization is the best, the most widely used methods of sterilization . Method is to require sterilization of materials in a pressure cooker (autoclave) inside , does not spill when heated steam , vapor pressure within the autoclave temperature increases rather increased. At 103.4kPa (1.05kg/cm2) vapor pressure , the temperature reached 121.3 ℃, for 15 ~ 20 minutes . Ordinary medium suitable sterile , physiological saline, surgical instruments, containers and glass syringes , dressings and other articles .
Autoclaves have lower row pressure pre-vacuum steam sterilizers and autoclaves two categories. Under pressure steam sterilizer row also includes portable and horizontal .More details,please feel free to visit http://www.autoclavesale.com/ site.
( 1 ) under the exhaust pressure steam sterilizer, the lower part of the vent , the proportion of differences in the use of hot and cold air during sterilization , with the upper part of the vessel vapor pressure forces the cold air from the bottom of the exhaust vent . Desired sterilization temperature , pressure and time according to the type of sterilizer , the nature of goods , packaging size vary . When the pressure in the 102.97 ~ 137.30kPa , the temperature can reach 121 ~ 126 ℃, 15 ~ 30 minutes to achieve sterilization purposes.
( 2 ) pre-vacuum steam sterilizer with vacuum before injecting steam into the first internal evacuated , a negative pressure to facilitate steam penetration. When the pressure 105.95kPa, temperature of 132 ℃, 4 ~ 5min to sterilization.
