Conditioning takes place firstly of your cycle. Air is removed from the chamber by Gravity displacement or Dynamic Air Removal methods and also the load is heated on the suggested sterilization temperature.

Exhaust is the final stage from the sterilization cycle when steam is faraway from the chamber as well as the force Within the chamber is produced. It really is also called the cool-down or drying period. Through this stage, a vacuum is drawn to eliminate the steam and to help dry the load.
