Method and use of sterilization
(Ⅰ) Portable autoclave
Structure
It is a dual-layer metal cylinder, with water between the two layers. The external layer is strong and thick whose upward side has metal and thick cover beside which there is a spiral to tightly close the closing cover and ensures the vapor not to overflow. Therefore, the higher the vapor pressure, the higher its temperature.
It is equipped with exhaust valve and safe piston to control the vapor pressure. The thermometer and pressure gauge can show the internal temp. and pressure. Inside the sterilizer there is metal chamber with hold to place the sterilized objects.
How to use the steam sterilizer
Add water to the external cylinder and place the table top autoclaves to the inner cylinder. Close the cover and tighten the spiral to make it sealed and closed. Heat up the lower part of the sterilizer with gas or electric furnace, and open the exhaust valve to empty the cold air, otherwise the pressure shown on the gauge will not all be the steam pressure, and cannot complete the sterilization.
After all cold are exhausted (namely the water vapor is continuously exhausted from the vent valve), please close the vent valve. Keep heating up and when the pressure is gradually rises to the needed pressure (101.53 kPa, namely 15 lb/in2, temp. 121.3 ℃), adjust the fire and maintain the pressure and temp. ( Notice: the pressure should not be too high in case there is accident) for 15~30min. Stop heating uo when the time is over. When the pressure reduces down to zero, please slowly open the valve to exhaust the air and open the cover to get the objetc. Please DO NOT suddenly open the exhaust valve when the pressure does not reduces down to zero incase the liquid in the sterilizer sprays out.
Vertical autoclave belongs to moist heat sterilization, which has three advantages: First, the thallus protein is easily degenerated; Second, it has strong moist-heat penetrating power; Third, when the vapor turns into water, there will exhaust mass heat to enhance the sterilizing effect. It can be used in heat-resistant and moisture-resistant products such as medium, physiological saline, clothes, gauze, cotton, dressings, glass equipment, infectious dirt etc.
Currently there is the portable automatic electric heating high pressure steam sterilizer is easy to operate and safe to use.
