The fundamental basic principle of steam sterilization, as achieved within an autoclave, is to expose each item to direct steam contact for the necessary temperature and force for the required time. Thus, you can find 4 parameters of steam sterilization: steam, strain, temperature, and time. The best steam for sterilization is dry saturated steam and entrained drinking water (dryness fraction ≥97%).813, 819 Force serves as a method to obtain the superior temperatures required to swiftly eliminate microorganisms.
