The basic principle of steam sterilization, as attained in an autoclave, is to reveal Each and every product to direct steam Make contact with in the required temperature and pressure for the required time. So, you can find 4 parameters of steam sterilization: steam, stress, temperature, and time. The ideal steam for sterilization is dry saturated steam and entrained water (dryness fraction ≥ninety seven%).813, 819 Stress serves as a way to get the high temperatures needed to quickly destroy microorganisms. Unique temperatures must be received to ensure the microbicidal exercise.
