The Class 2, Type B2 Laminar Flow Biosafety Cabinet provides a high degree of localized protection from particulate and aerosol hazards. The work area is continuously bathed with laminar flow ISO 5/Class 100 HEPA-filtered air, while a negative pressure airflow into the cabinet protects the user. This is a 100% Total Exhaust unit. The equipment must be ducted to the outside of the building, with no recirculation of air in the cabinet. That total-exhaust design makes the B2 hood suitable for handling not just particulates but fumes and gases, and helps eliminate cross-contamination and the accidental release of pathogenic microorganisms or carcinogenic aerosols to the outside environment.

All-stainless-steel construction holds up under the wide range of cleaning chemicals laboratory and cleanroom use demands, giving these cabinets a long service life.
