The essential theory of steam sterilization, as completed in an autoclave, is to reveal Each and every product to direct steam Get hold of for the needed temperature and pressure for the required time. Consequently, there are four parameters of steam sterilization: steam, stress, temperature, and time. The perfect steam for sterilization is dry saturated steam and entrained drinking water (dryness portion ≥ninety seven%).813, 819 Force serves as a means to obtain the high temperatures required to speedily destroy microorganisms. Particular temperatures needs to be obtained to make sure the microbicidal action.
