Product Introduction

The Class II B2 biological safety cabinet is a state-of-the-art safety device that fully complies with the ANSI / NSF49:2016 standard. It offers advanced negative pressure filtration to provide comprehensive protection for laboratory personnel, the environment, and experimental materials. Designed with ergonomic comfort in mind, the cabinet features a 10° tilted design that enhances the viewing angle and makes operation more comfortable. The work area is constructed from seamless, integrated 304# stainless steel with 8mm rounded corners, ensuring easy cleaning and maintenance. With negative pressure surrounding the workspace on all four sides, the Class II B2 biological safety cabinet ensures superior safety and protection against airborne contaminants.

 

The cabinet's basin-shaped work surface, made from premium 304# stainless steel, prevents any spillage from reaching the liquid trough, simplifying cleanup. Its innovative Forma caster design allows for both mobility and stability, and the detachable frame enables customizable height adjustments to suit varying needs. For convenience, both the filter and fan are easily accessible from the front, simplifying maintenance procedures. The front window features double-layer laminated safety glass, offering protection in the event of breakage while allowing continuous operation without disruption.

 

Equipped with a high-brightness LCD screen, the Class II B2 biological safety cabinet displays real-time data such as airflow velocities, filter status, workspace temperature, and humidity, making it easy to monitor critical operational parameters. The motorized front glass door is operable via foot pedal, button, or remote control, automatically stopping at the safe operating height. The cabinet also includes a timer function for scheduled start-up, shutdown, and UV disinfection, streamlining workflows and enhancing laboratory efficiency.

 

Rigorous airtightness testing ensures the safety and stability of the cabinet during operation. The integrated alarm system provides audible and visual alerts for parameters such as glass door height, filter pressure, filter lifespan, and airflow fluctuations. Smart interlock protection prevents operational errors, ensuring user safety and extending the longevity of the equipment.
