The fundamental theory of steam sterilization, as achieved in an autoclave, is to expose Each and every item to direct steam Speak to with the essential temperature and force for the desired time. As a result, there are 4 parameters of steam sterilization: steam, force, temperature, and time. The perfect steam for sterilization is dry saturated steam and entrained drinking water (dryness fraction ≥ninety seven%).813, 819 Force serves as a way to get the large temperatures essential to quickly get rid of microorganisms. Precise temperatures have to be acquired to ensure the microbicidal exercise.
