Hello
I work at a small college where we are thinking of buying a portable fumehood for doing lecture demonstrations in chemistry.
It's hard to decide if it would be worthwhile (~7000 $CNDN) without having seen one in operation. Can they handle the smoke of a gummi bear combustion? The sparks from thermite? Are they noisy to speak over? How is the glare/visibility through the plastic?
If anyone on the forum has experience with ductless portable fumehoods for demos, either as lecturer or student, I would appreciate your opinion.
Thank-you
