The fundamental theory of steam sterilization, as completed in an autoclave, is to reveal Each and every item to immediate steam contact with the required temperature and pressure for the specified time. So, there are actually 4 parameters of steam sterilization: steam, force, temperature, and time. The ideal 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 high temperatures essential to swiftly get rid of microorganisms. Particular temperatures should be acquired to ensure the microbicidal exercise.
