Classification of Sterilizers:
Portable sterilizers are regular and automatic
Automatic type: good sealing performance, effectively prevent steam leakage; pressure gauge equipped can visually indicate the working pressure and the corresponding temperature, which could help to grasp the sterilization effect; and it is equipped with the safety valve, to ensure safety operation; automatic type general configuration of the imported water device, which could detect the chamber water shortage in the first time, absolutely safe and reliable; automatic type can automatically control the pressure required, without artificial guard master; automatic type can automatically controls the sterilization time;
Ordinary type: double scale, two kinds of counting pressure meters, over pressure self discharge, low water level electric heating tube, electric heating mode. Limitations of sterilizers
limitations: small capacity.
Portable sterilizing pot
Years ago it will need someone to watch during operation, because the automatic control device without pressure and temperature, the temperature or pressure to achieve the required (121 degrees 0.1MPa), to cut off the power supply to stop heating. When the temperature drops, the power is switched on and the temperature is kept within a constant range. Because the temperature is too low to achieve sterilization, it can be dangerous if it is too high. So the operation is rather troublesome. But now this ancient sterilization pot has been rare, and now on the market, portable sterilizer also achieve control automation, but because of the pressure of sterilization is relatively large, it is better to have someone in the field for insurance.
Generally speaking, water should be added before each sterilization. Water can not be too little, otherwise it will cause dry or burst. Add water. The best resulting deionized water, scale less.
The most common test method is to put the sterile medium in 37 degree incubator for 24 hours. If there is no growth of miscellaneous bacteria, the sterilization effect is also acceptable.
High pressure steam sterilization for a wide range of applications. Generally used in laboratory medical institutions, other methods such as dry heat sterilization, the effect is very good. But the scope of application is small. In addition, bath disinfection, high temperature instantaneous sterilization, intermittent sterilization and filtration sterilization are commonly used in industrial production. These methods are either made to be larger or are used for sterilization of certain materials. Each has its own limitations. High-pressure steam sterilization is suitable for laboratory medical institutions, industrial production and so on.
