Just be aware that exposing wood fibers to some of the acids used in refining can create a fire hazard at the minimum.
Oh alright, will bear that. Ive to replace a shelf on this anyways as its wood is torn exposing the underlying fibers as mentioned. Also Ive to cover it with an epoxy paint I guess Ill give it a white one.Just be aware that exposing wood fibers to some of the acids used in refining can create a fire hazard at the minimum.
Slow reactions in large beakers filled to max. one third to leave room for the vapors (NO2, HCl) to condense back on the wall and watch glass to reuse the acid and your fume hood fan will dilute and disperse the few vapors that do will be escape below emission levels in terms of grams per kubic meter of expelled air.if someone has a better suggestion kindly redirect me there.
If you use a venturi to suck air from the hood, it does not matter which kind of fan you use. As long as the output is good enough to make it work.I still am confused about the fan and/or blower needed in this setup.

On the other hand I redrew the diagram based on what I understood so please do correct me if wrong again. Also would I really need a blower here or another simple fan would do the trick too?If you use a venturi to suck air from the hood, it does not matter which kind of fan you use.

Test the flow at the opening of the fume hood with the smoke of an incence stick.
A venturi basically means creating a conical restriction at the point where the fume hood air comes in.
I'd do it the opposite way.Thanks for the response,
All my procedures are carried out with a watch glass, barely do I remember doing any without it.. I have seen some fume emissions but if they can be controlled by so much then I think as you have mentioned it ahould be okay.
