Class II B2 Biological Safety Cabinet

Total-exhaust containment for demanding applications. Class II B2 cabinets protect personnel, products and the environment while exhausting 100% of filtered air through a dedicated top connection. With no air recirculated into the work zone, the design is suited to procedures involving limited quantities of volatile chemicals or radionuclides when connected to a properly designed exhaust system.

0%air recirculation
100%filtered air exhaust
3-waypersonnel, product and environmental protection

Advantages

  1. Three-way protection for personnel, products and the surrounding environment.
  2. 100% filtered-air exhaust prevents air from being recirculated into the work zone.
  3. ULPA filtration reaches at least 99.9995% efficiency at 0.12µm.
  4. Stable inflow and vertical downflow help maintain the protective air barrier.
  5. A 200mm operating opening balances access with containment performance.
  6. The fully finished SS304 work area is durable and easy to clean.
  7. Integrated LED and UV lighting supports visibility and work-zone decontamination.
  8. The top exhaust outlet supports connection to a dedicated building exhaust system.
  9. Universal wheels with adjustable leveling feet simplify positioning and installation.
