What's a Class-B Sterilizer?

A Class B sterilizer (such as Clearbrook Dental's Bravo 21V) is a steam sterilizer with high levels of sterilization. It uses a vacuum pump and steam mixtures to clean the chamber before the sterilization cycle begins. This can eliminate 99% of the air from the chamber before temperature and pressure rise to the required parameters. The chamber can be cleaned out of 99% of the air before the temperature and pressure rises to its required parameters.

What's the difference between a Class N and Class B Autoclave Sterilizer?

The primary difference between a Class N (Gravity Displacement Steerilizer) and a Class B sterilizer is how the air is removed from the chamber before sterilization begins. This determines which type of instrument/material or item can be sterilized in a Class A sterilizer vs. a Class N sterilizer. These sterilizers make use of steam from a boiler or steam generator to cause a downward displacement. This pushes out any air in the chamber before the sterilization cycle begins. This method of air removal uses steam to remove the air from the chamber. However, depending on how the steam was expelled, it may not completely eliminate air from hollow or porous instruments. With the aid of a vacuum pump, a Class B sterilizer can provide greater air removal for the most difficult load types. The vacuum pump allows for better steam penetration into more difficult load types, ensuring that the load is properly sterilized before it goes to use. The Class B sterilizer is the most compact, efficient, and effective tabletop sterilizer on the market. It can sterilize any type of load used in dental, medical podiatry and tattoo markets.

Dental Clave B Sterilizer is different from other sterilizers in that it can provide optimal air removal using a high-quality pulsating vacuum pump. This vacuum pumps removes air pre-sterilization as well as post sterilization. Clave B sterilizer also uses a steam generator that can inject small amounts of steam into the chamber for fast and efficient sterilization.

Clave B is easy to use, has 5 cycle types, and 3 test programs. It can handle all types of material/loads. The device's effectiveness is validated by running test programs such as Bowie and Dick Test, Vacuum Test and Helix Test.
