The basic principle of steam sterilization, as attained in an autoclave, is to reveal Every single item to direct steam Make contact with in the required temperature and tension for the desired time. Thus, you will find four parameters of steam sterilization: steam, force, temperature, and time. The best steam for sterilization is dry saturated steam and entrained water (dryness fraction ≥ninety seven%).813, 819 Pressure serves as a way to acquire the higher temperatures needed to rapidly eliminate microorganisms. Specific temperatures have to be obtained to ensure the microbicidal activity.
