The essential basic principle of steam sterilization, as accomplished within an autoclave, is to expose Each and every item to immediate steam contact on the necessary temperature and stress for the desired time. Thus, there are 4 parameters of steam sterilization: steam, stress, temperature, and time. The perfect steam for sterilization is dry saturated steam and entrained water (dryness fraction ≥97%).813, 819 Tension serves as a method to get the large temperatures necessary to rapidly eliminate microorganisms. Particular temperatures needs to be acquired to make sure the microbicidal action.
