These kinds of laminar flow hoods are also known as clean benches.
Not intended for employee protection
Make sure the plastic (I recommend Polypropylene) of which it is made will meet the local fire authority flame spread index requirements. Nothing like a BIG
chunck of plastic to get a fire really going….

Okay. That was my Duh! moment for the day. Of course I needed more details and I have them.
We need the laminar flow cabinet to provide bacteria free and metal free air for working with phytoplankton. So it is biological, but we aren’t working with
anything that is a biohazard. There also will not be anything hazardous, so outside exhaust is NOT needed. (There is a traditional fume hood in this space already.)

Shelly,
Does the user need protection? Are they going to be working with infectious bioorganisms and/or human cells? A laminar flow hood won't protect the user, only the product.
If they will be working with infectious materials a biosafety cabinet (rather than a 'laminar flow hood') provides both product protection and user protection. It has laminar flow...
In case you need a BSC, below is the link to get the Appendix A from the BMBL. (I can't attach the pdf).
We have both IIA2 (the majority) and IIB1 (a few). I am perfectly comfortable with the IIA2's (which discharge into the room) as long as they are for BSL2 work and are certified
annually or when moved.
let me know if you'd like to talk further.

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!!
