Biological Safety Cabinet Class II A2 (11231 BBC 86)

Three protections: operator, sample and environment. Airflow system: 70 % air recirculation, 30% air exhaust A2 Cabinet is suitable for working with microbiological research in the absence of working with microbiological research in the absence of volatile or toxic chemicals and radionuclide.


  • Motorized front window.
  • Time reserve function.
  • ULPA filter life and UV life indicator.
  • Automatic air speed adjustable with filter block.
  • With memory function in case of power-failure.
  • Audio and visual alarm (Abnormal airflow velocity; Filter replacement; Front window at unsafe height).
  • Work area surrounded by negative pressure, it can ensure maximum safety in work area.
  • Audio and visual alarm (Filter replacement, window over height, abnormal air flow velocity etc).
  • Remote control: all functions can be realized with it, making the operation much easier and more convenient.
  • Interlock function: UV lamp and front window; UV lamp and blower, LED lamp; blower and front window.
