Make sure that a laminar flow hood is really what s/he wants. People use the term "laminar flow" when they really mean Biological Safety Cabinet (BSC).
Laminar flow hoods ONLY protect product (whatever is in them) from contamination. They do NOT protect the worker from whatever biohazard (microorganism) they are using in the hood.
Most BSC's and laminar flow hoods are self-contained, not ducted and they work with a HEPA filter. The point of a laminar flow or BSC is NOT to remove vapors as a chemical fume hood does, but to keep "bugs" either out of the hood as in laminar flow or both in and out as in a BSC.

One of my faculty is interested in a laminar flow hood. I know nothing about them.
What do I need to know?
Are the self-contained ones any good?
Which brands are best?

Thanks for your help!!
