New Fume Hood
So I just a new (used) fume hood. It has electric outlets, water outlet, and gas outlet. And the best part is that I got it for.... drum roll
please...... $75!
It is a bit old, but the fan is good, and it serve my purposes. Plus for the price how can you beat it.

Excellent find zoombafu ! I'm jealous. I have a crappy home made one I use now for tame reactions, and I just go outside for some. I would really love
a nice hood, and I hope to build a good one as soon as i can afford to. I don't know to much about hoods but that looks like a nice one. Especially
for 75 bucks. Are you just venting to outside, or are you employing some sort of scrubber/filter?

Indeed an excellent find! I paid more than $75 for the sash on my home-made hood. I wouldn't care to admit what I paid for the blower. Was the
blower included with your hood?
I reommend testing it with something like ammonia before using it for anything really toxic, especially if the blower is in the hood so that the
exhaust duct is under positive pressure.

Well right now I just have the blower venting outside. In the future though I plan on adding an activated carbon filter, and possibly some sort of
gas scrubbing setup.
The blower seems to work ok (its a bit old so i'll probably replace it for a quieter, stronger, and more efficient blower), I tested it when I was
cleaning the inside with HCL (there were some rust spots on the stainless steel), and I didn't get dizzy from the fumes or anything like that.
In the future I also want to be able to use it as a sterile glove box .I like doing stuff with bacteria, fungus, and all that type of stuff where
anything can easily contaminate a culture. But I have an ozone generator that I can use to flush the enclosure out, so hopefully I can use it for
sterile work.

Has anyone ever considered the possibility of running inert gas lines into the hood and perhaps setting up a schlenk line?

I hear a good way to test efficiency is with a small sugar fueled smoke pot. Maybe KNO<sub>3</sub> or KClO<sub>3</sub> as the
oxidizer in a slow-burning proportion. It is very visible smoke, but not that harmful if there are leaks or if the fan cant keep up.

Another good way is to light a cigarette. Its not harmful (well it is in the long run, but a wiff of smoke won't kill you), and you can easily see
the smoke. A good test that I have heard for testing a fume hoods efficiency is lighting a cigarette outside of the hood, and a good hood should draw
the smoke in even when you are standing a few feet away.

I bought a load of those little smoke matches you can buy at hardware shops for testing flumes . . .the smoke is very visible and just in the right
quantity for testing a fume hood.
