The basic basic principle of steam sterilization, as completed within an autoclave, is to reveal Just about every item to immediate steam Call for the essential temperature and stress for the required time. Hence, you'll find four parameters of steam sterilization: steam, tension, temperature, and time. The ideal steam for sterilization is dry saturated steam and entrained drinking water (dryness portion ≥97%).813, 819 Tension serves as a method to obtain the large temperatures needed to immediately eliminate microorganisms.
