Laminar Flow Hood vs Biosafety Cabinet — Which Do You Need?

The critical difference

A laminar flow hood (clean bench) protects only the product: HEPA-filtered air flows across the work zone toward the operator. A biosafety cabinet protects the operator, product and environment. This distinction is safety-critical.

When to use each

Use a laminar flow hood for non-hazardous sterile work (media prep, electronics, sterile assembly). Use a biosafety cabinet whenever you handle biological agents, toxic, infectious or hazardous materials. Never use a laminar flow hood for hazardous materials — it blows contaminants toward you.
