Types of Bio Safety cabinets

Biosafety Cabinets (BSL Cabinets or BSC Cabinets) are one of the most useful ventilated laboratory workspaces in dealing with risky biological agents. It’s mostly used in clinical and medical research settings where the samples can be contagious and highly risky. To protect the user and the environment, it’s key to make use of a well-ventilated and tested BSL cabinet. 

Based on the biological agent that is being tested and the level of protection that is needed, we classify BSL cabinets into several types listed below in this infographic.

Class I BSL-1, BSL-2, BSL-3
  • Low to moderate risk biological agents
  • Personnel & Environment protection
  • HEPA filter is used for filtration of air before it’s released
  • Personnel are protected by moving the air away from them
Class II BSL-1, BSL-2 BSL-3
  • Low to moderate risk biological agents
  • Product, Personnel & Environment protection
  • Front access door with maintained airflow; HEPA flow within the area & exhausted air
  • Four subtypes – A1, A2, B1, B2 (dependent on their minimum inflow velocities & exhaust systems)
Class III BSL-4
  • High risk biological agents
  • Maximum protection – Personnel, Product & Environment
  • Known as ‘Glove Box’
  • Any material that enters or is removed is passed through a double-door autoclave
