Nice setup Magpie.
The one thing I am glad I did when I installed my hood was to set it on a drain pan.
I went to a local stainless steel shop and had them take a heavy gauge SS sheet and break a shallow bend from corner to corner such that it made a low
spot in the center. Then I had them `cut a round hole in the center and weld a sink drain in. I built the stand for the hood out of 2x4's and
supported the bottom pan around the outside edge, and screwed it down. I then ran a good bead of silicone sealant and set the whole hood down on it. I
located my hood next to my sink and plumed it into the same drain.
Lastly, I put some sides and doors on my base frame and it made a great acid cabinet.
Having water and a drain in the hood is the cats ass!

Chemoleo I agree that the fume hood capture is very efficient. When I was generating ammonia in an attempt to upgrade ammonium hydroxide to reagent
strength I never smelled a thing! This hood will allow me to conduct experiments and syntheses I couldn't otherwise do.
Call me paranoid but keeping a low profile is very important to me. Just the sight of a beaker or RBF is enough to strike terror into the hearts of
the chemically ignorant. So I don't do experiments in my backyard.
In my garage I'm lucky enough to have a window with southern exposure. So I get loads of wonderful sunlight coming in during the winter when its
needed. I purposely put the hood in the SW corner where it can't be seen through that window from the neighbor's backyard.
But as a consequence of its location I'm a long ways from the drain in my east wall. So I can't easily get the nice features that
Ordenblitz has. You can always run water but drains require proper slope - unless you want to install a lift station w/sump pump.

Awesome setup Magpie! Your fumehood beats my 'fumehood', if you can call it that, mine is a lucite box on a dryerhose with a beefy 120V
computer fan. And I cannot even use it in the same room as my lab anymore!(lab switched rooms, it was built into a window.)
EDIT: Forgot to ask, where are you getting those hose barbs? The Rona/Revy near me does not have them.

Thanks rogue. Those barbs are 1/4". On the outside it has female NPT. This is mated to a male NPT barb that you see on the inside. Use
washers for spacers as required.
My local Ace Hardware store carries these with the other brass pipe fittings.

This thing popped up again so...
I am sorry to dig this kind of old thread, but Bromine asked (http://www.sciencemadness.org/talk/viewthread.php?tid=7017) for pictures. So I thought why not add a picture of my own.
Picture updated.
Ringstands, clamps, jacks etc. are in the cuboard with periodic table on it. The cuboard at the left side of the picture contains glassware and
organic chemicals. The cuboard under the table with the "corrosive" sign contains mineral acids and solvents. Inorganic chemicals are in the cuboard
next to the one with organics, sadly it is not in the picture. Oh and .. yeah, I really do have a rotary evaporator

Your fume hood looks awesome, Magpie! I've never seen one that is clad with metal on the inside.
kaviaari, what's in the nice Scharlau reagent bottle on your table?
I'm going to post pics of my lab as soon as I have cleaned it up a bit- it's incredibly messy at the moment.

It's anhydrous chromic acid and if I remember right when I took that picture I was making ammonium dichromate. I suppose that the small 50ml beaker
with stirring rod is chromic acid solution.

Laboratory Pictures
Just a smattering of pics from the old laboratory my friend and I experimented in. Might as well post them.
Ok, the picture with the shelves of the glassware is only about a quarter of our glass, the rest was boxed up for a move. On the top shelf you see
some boxes (fritted filtration setup), 700mm liebig, 400m Hempel, and then a large 40 theoretical plate fractioning column that's kinda hard to see.
And yes, that is a 12" diameter buchner for scale. As far as Jesus goes, don't ask why there's a hole in his feet.
The picture of the household products shows our reagents. Most of the organics have been redistilled and rebottled, so that's just feedstock
containers. All of the baggies in the middle of the picture are various transition metals. Up on top are (empty at the time of the photo) where we put
the powdered metals and oxidizers in those large 3 gallon jars. In the left foreground is our Mettler analytical balance, on the right, our lab
aprons.
Other photo is just of some random glassware, beer can is for scale. There's also a picture of our hydrogenator, it has 60 psi of H2 in it.
Last photo is of the large equipment, a 20L filtering flask for precious metals work, and the as-of-yet, unused 55L 24/40 jacketed pressure reactor
flask, which I wanted to use for the hydrazine sulfate scale up, but now my friend and I are using it for Na methoxide prep of biodiesel. -Fleaker
P.S. This is NERV here, and yeah that beer is my own special treat, lol  . Oh,
and yeah sorry for not posting this year: I have been busy as hell with college and work.
Edited for accidental misinformation-those jars on top of the shelves were empty when I took this photo. They've since been filled.

Interesting pictures Fleaker, but I'm mostly jealous that you have a lab partner. It gets kind of lonely out in my lab at times.  Then again there are never any disagreements about what expeiment to do next or who
should clean up the dirty glassware. 
That hydrogenator is interesting. I have wished I had a Kipp generator at times. I've seen them on e-bay for ~$300 but I don't want it that bad.
Some of your reagents look familiar, ie, Red Devil lye, Ace toluene, and those blue solvent cans.
By the way are you and NERV pulling an all-nighter making that fuming nitric? Is that the way chemists celebrate New Years?

Gnaw, their way of celebrating new years is understandably more dramatic (hey, I think I see a jug of potassium permanganate there, and I bet it's
lighter in weight since last night!). I'll let him expand if he wants.

Off topic but Magpie, I must say that your fume hood is absolutely amazing. I hope to use your basic design premise in the hood. Fleaker and I are
currently attempting to build a larger version in our own lab. My original idea was fairly skimpy and left a lot to be desired, but with the design
you have put out, and a little alteration in materials used an excellent fume hood can be made relatively cost effectively. Thank you very much for
your beautiful lab pictures. It’s almost like looking at super dirty porn when it comes to goggling at another’s laboratory .
Lol, yes it is very nice to have a lab partner, but when it comes to what experiment to run next we can get on each others nerves. Glassware cleaning
is not much of an issue though Fleaker always likes to leave up to me (seems he’s always got to go home just before clean up, lol jk) .
Oh, and yeah this is definitely an all-nighter to get this nitric acid made up. We just switched flasks since our pear was full.
P.S. Sorry about misspelling grammar is not my strong point; Fleaker usually has to fix my posts up. I guess I am just a rough around the edges kind
of guy.
P.S.S. actually no pyro this new years at least for me Fleaker had his own fun.
This nitric acid more than makes up for it though! Oooooo the best part we didn’t even have to pay for the hydrogenator! It was a donation from a
very generous Dr. at a local collage.

Words cannot express how jealous I am of that 55L jacketed flask you've got. Sure, I have no use for something like that but damn I could find a use.
I'd take pictures of my lab but right now it is incredibly messy, didn't clean it up from my new years work since I've been too busy. Dirty flasks
and beakers everywhere, paper towels everywhere, etc etc

I`m not sure if I should post in here or make a new thread entirely?
but since others have I will add to this one rather than make an entirely new one.
this should give a reasonable 1`st impression of what will meet you when you enter:
this is in the Stock room:
obviously there`s plenty that you Can`t see as it`s in closed drawers or boxes etc...

An impression of my lab:
A lot of storage space:
The contents of my storage space (chemicals and electronics stuff, also HV-stuff). Some people may recognize material, which I have on my website:
My lab consists of two rooms, which are connected to each other through some kind of "port". I have a roof window for ventilation and daylight (from
the south). In hot days I can dim the sunlight with a sheet on the outside of the window.
This is the darker part of my lab, with lots more chemicals (many very small bottles, tens of grams per bottle). Here, I also have running water.
Below follows an overview of that part of the lab. There is some "fume hood", but that only is useful for experiments where not too much gas is
produced or not too toxic gas.
Finally, when I do experiments which produce lots of toxic gas, or when I use the really nasty ones, such as thionyl chloride, then this perfectly
ventilated room is used (not the red, but the green room ):
Making this lab was quite a lot of work, but I do not regret this (I made this, together with my father, last spring). The only thing which really
needs improvement is the fume hood. That may be a project for next spring.
The best thing is the large amount of storage space and the presence of hot and cold running water. All required tubing is nearby, because the boiler
and heater already were present. Just needed to make some T-taps from the existing tubing.
EDIT: Changed links, so that they work again.

Yes, the backyard also is of great value. Not only for experimenting, also a good place to be in summer time (appr. 500 m2 total area). In summer
time, the green stuff also gives good coverage. I have a lot of privacy in the backyard at that time, and then I can do nice experiments outside
without having many prying eyes watching what I am doing.

Very nice YT2095. Looks warm and cozy. It thoroughly looks like a place for discovering the wonders of chemistry. I see the Kipp generator and am
getting jealous.
Woelen that is really first class! And very well equipped too. I am jealous of your outside facility as I have some experiments in mind for that
kind of location. Although I have a large backyard, I am not as well protected from prying eyes.

No, these pictures were taken last spring (IIRC end of March). But the grass still is as green as on the picture, the trees, however, now don't have
any leaves anymore.
In summertime the trees are MUCH bigger than on the picture. I prune them every early spring, otherwise our garden soon becomes a forest .

This is a reply to "benzylchloride1" about what blower to get for his Kewaunee hood. I moved this post from his NBS thread as it was off-topic there.
___________________________
To get a feel for what blowers are available and appropriate take a look at the Kewaunee site (go into the specs and drawings on the pdf's). You can
also look at the other hood manufacturers' sites.
You can spend a lot of $ on a blower or you can go cheap like I did. I imagine that explosion proof, variable speed, Teflon coated, and other special
features are all available for the right price.
If you decide to go cheap I estimate that you can buy one from Grainger for under $300. This is for a constant speed, open one-side, "non-explosion
proof," epoxy painted steel blower. My blower moves about 400-500 cfm at about 0.75" H2O pressure drop. Try to keep your ducting short and use minimal
restrictions (elbows, reducers, etc). I mounted my blower on the ceiling joists almost against the outlet vent high on the wall. It is mated to the
wall using an outlet plenum. Most of the ducting then is under suction. Professional labs usually elect to mount their blowers on the roof then add a
10' stack. I didn't do that. You can, however, if you don't mind attracting the extra attention you would surely get.
I designed the hood and the outlet plenum then had each fabricated by sheet metal shops - again not cheap.
Standard duct diameter is 10". I used 8" and it works just fine. Your design target is ~100 ft/min for face velocity of air moving into the hood. So
you select a blower that can provide this based on its "fan curve," a plot of flow (cfm) vs pressure drop ("H2O).
You can see pictures of my hood installation and get some specs earlier in this thread. If you have any other questions just ask. BTW my ducting is
PVC and the outlet plenum is stainless steel.
FYI, the particular blower I bought is:
http://www.grainger.com/Grainger/items/7C651
Grainger may not sell this direct to the public. I had to get an HVAC dealer to order it for me.

Very nice set up you have there magpie! I REALLY love the vent hood, i have the materials to build mine but i have no room
I will have to take pictures of mine next time I'm bundled to go out side (my garage is my lab)
Oh, btw i am new here. Ive lurked around for a few moons but never got around to registering.
Great forum guys keep it up!
