Class II B2 Biosafety Cabinet working principle:

The biological safety cabinet is a box-shaped air purification negative pressure safety device that can prevent dangerous or unknown biological particles from being contained in aerosols during operation.

Its working principle is mainly to pump in the air inside the cabinet to maintain the negative pressure inside the cabinet, thereby protecting the operator through vertical airflow. The outside air is filtered through the HEPA filter and then enters the safety cabinet to avoid contamination of the sample. The air in the cabinet is also filtered through HEPA filters and then discharged into the atmosphere to protect the environment.

Class II B2 Biosafety Cabinet Features:

◆ Designed to discharge HEPA filtered exhaust air directly into the laboratory, or into an exhaust system connected through an optional awning

◆ Stainless steel housing and work area

◆ Ergonomic angle front improves coverage and comfort reduces glare

◆ Effective filtration system

◆ The sliding door system adopts patented technology and can be placed at will

◆ Stainless steel workbench is easy to clean

◆ The lighting system and disinfection device have been installed

◆ Sliding window limit buzzer and flashing alarm

◆ Installed with wireless remote control, easy to operate

◆ High performance fan system

Installation of Class II B2 Biosafety Cabinet:

1. The biological safety cabinet shall not be placed on its side, impacted, or collided during transportation, and shall not be directly attacked by rain, snow, or sun exposure.

2. The working environment of the biological safety cabinet is 10~30℃ and the relative humidity is <75%.

3. The equipment should be installed on a horizontal surface that cannot be moved.

4. The equipment must be installed close to a fixed power socket. When the external exhaust system is not connected, the top of the device must be at least 200mm away from the obstacle at the top of the room, and the distance between the back and the wall must be at least 300mm to facilitate the smooth flow of external exhaust. Maintenance of safety cabinets.

5. In order to prevent airflow interference, it is required not to install the equipment in the passage of people, and not to make the operating port of the sliding front window of the biological safety cabinet face the door and window of the laboratory or be too close to the door and window. Places that may disturb the airflow.

6. When used in high altitude areas, the wind speed must be recalibrated after installation.
