Therefore, you can find 4 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 method to get the high temperatures essential to rapidly eliminate microorganisms. Distinct temperatures need to be acquired to make sure the microbicidal activity.
