What is autoclave principle?
The basic principle of steam sterilization, as accomplished in an autoclave, is to expose each item to direct steam contact at the required temperature and pressure for the specified time. Thus, there are four parameters of steam sterilization: steam, pressure, temperature, and time.
How long should an autoclave last?
five to ten yearsWith proper boiler maintenance and attention to water quality, heating coils should last five to ten years on average, although decreasing efficiency and performance may be experienced. Depending on water quality, and the number of cycles run, it is recommended to blowdown the generator daily or weekly.
What precautions needs to be taken when using an autoclave?
Always use personal protective equipment (PPE) when using an autoclave. Wear a lab coat, heat-resistant gloves, and safety glasses. Be sure arms are covered by a lab coat and longer heat-resistant gloves to prevent burns from heat and steam.

What is the advantage of autoclave?
1 Autoclaving destroys microorganisms more efficiently than dry heat and hence the material is exposed to a lower temperature for a shorter period. 2 It is used for sterilization of a large number of official injections.
Can you leave an autoclave on overnight?
