Effective air removal
For a complete and reproducible removal of air from the autoclave and the product to be sterilized, a fractionated pre-vacuum is to be used. Therefore, the autoclave is equipped with a vacuum system. During the heat-up phase, vacuum cycles take place for effective air removal followed by steam injections. Usually, a threefold fractionated pre-vacuum is applied - depending on the product, however, even more fractions may be necessary.
Drying of solid objects
Solids such as instruments or empty glassware are usually put inside a drying oven following the sterilization process. State-of-the-art autoclaves allow for drying solids directly after the sterilization process. Sterilization and drying in one process. Further handling of the sterilization material possibly causing recontamination is not necessary.
