Whether fitting out a new practice, replacing a broken-down machine or simply upgrading, deciding on the best autoclave to buy should not be a rushed decision. As an expensive piece of equipment that plays a pivotal role in infection control, your autoclave should tick as many boxes as possible.

Our Ultimate Guide to Autoclaves will arm you with everything you need to make an informed purchase.

How do autoclaves work?

Autoclaves use steam to create a high-pressure environment at a temperature too high for microbial survival. This eliminates pathogens that may be resistant to soaps and detergents. The steam created in the autoclave allows for thorough sterilization within dental instruments and tiny holes and crevices that could be missed during cleaning with detergent.

1. The first stage of the autoclave sterilization process is sometimes referred to as the “purge” phase. This is when steam created from heating water displaces the air within the autoclave chamber. Both temperature and pressure then begin to increase.
2. The second stage is the sterilization phase. During this phase, the exhaust remains closed causing the temperature and pressure to rapidly rise to the desired levels required to destroy bacteria, spores and other pathogens.
3. The third phase is the exhaust phase. This is when pressure is released from the chamber, but temperatures remain high.
4. The fourth and final stage is the cooling down phase. Once temperatures are low enough, the load can be removed from the chamber ready to be reused.
