Class B Benchtop Autoclave Application:
Class B Benchtop Autoclave is a high-performance compact sterilization device featuring a multi-pulse pre-vacuum air removal system. The post-vacuum drying function addresses the industry pain point of damp and easily contaminated loads after sterilization. It is a cost-effective sterilization option for small and medium-sized enterprises and professional organizations.
Class B Benchtop Autoclave Feature:
- Efficiently removes over 99% of the air from the sterilization chamber, ensuring saturated steam penetrates to the deepest parts of the sterilized load.
- 0.22 μm high-efficiency sterilizing air filter to prevent re-contamination of sterile items.
- Built-in open-type condensate water tank for easy cleaning, equipped with water level monitoring for real-time monitoring of the tank water level.
- The sterilization chamber and door cover are made of 304 stainless steel.
- LCD screen can display temperature, pressure, time, operating status, fault alarm,
- Equipped with a variety of safety protection functions, including over-temperature/over-pressure protection and safety interlock protection.
- Built-in printer that prints information such as date and time, device information, and program process parameters.
- Optional water quality testing function to ensure that the water quality meets requirements.
Specification. - Multiple programs are available: built-in bare-metal program, encapsulation program, BD test program, Helix test program, and vacuum test program. Sterilization and drying times are adjustable to meet diverse sterilization needs.

What Does “Class B” Mean in an Autoclave?
“Class B” is the highest sterilization classification for small steam sterilizers under the European standard EN 13060. A Class B autoclave uses a pre-vacuum and post-vacuum system to remove air from the chamber before sterilization, allowing saturated steam to fully penetrate all types of loads.
Difference between Class N and Class B autoclaves
| Feature | Class N | Class B |
| Vacuum System | No | Yes |
| Wrapped Instruments | Limited | Yes |
| Hollow Instruments | No | Yes |
| Porous Loads | No | Yes |
| Sterilization Capability | Basic | Advanced |
Class B offers the highest sterilization capability.
How Does It Work?
Before steam enters the chamber, the vacuum pump removes trapped air.
This allows steam to penetrate difficult areas such as the following:
Hollow tubes
Wrapped packs
Porous materials
Typical sterilization conditions include 121 ℃ or 134 ℃ under pressurized saturated steam.
