The most advanced autoclave sterilizers in the market are Class B autoclaves which have been engineered to fulfill the strictest sterilization requirements. Their vacuum pump removes air from the chamber both before and after sterilization to improve steam penetration and drying.
Autoclaves receive their “Class B” designation through the performance criteria established by the European standard EN 13060. Class B autoclaves are capable of sterilizing:
Hollow instruments (e.g., dental handpieces).
Wrapped items.
Porous loads.
To gain foundational knowledge about autoclave sterilization refer to our article .
A Class B autoclave operates by following three distinct phases.
The vacuum pump expels air from the chamber as well as from inside the instruments before the sterilization process starts.
This process allows steam to reach all the intricate surfaces and hollow areas.
During sterilization, steam enters the chamber where it reaches the necessary temperature of 121°C or 134°C along with the proper pressure level.
Sterilization duration remains constant only after consideration of load type characteristics.
The vacuum pump removes moisture from sterilized items after sterilization so that they become dry and ready for use.
