What is sterilization principle?

The basic principle of steam sterilization, as accomplished in an autoclave, is to expose each item to direct steam contact at the required temperature and pressure for the specified time.

What is the principle behind sterilization in an autoclave?

moist heat sterilization

The autoclave works on the principle of moist heat sterilization. The high pressure inside the chamber increases the boiling point of water for the sterilization of equipment. The higher pressure also ensures the rapid penetration of heat into the deeper parts of equipment.
