distillation apparatus
Hi, im new to chemistry so i dont know the price that a distillation apparatus should be. So i was wondering if anyone could tell me if this is a good
deal.
Thanks
shippings 15 dollars it says

I'd say that's an amazing deal. The real question is what is the quality of the glassware. I'm a bit skeptical.
[EDIT] Shipping's going to also be an issue (unless you live in or near China).

I bought a distillation apparatus last week. I got it in on Friday, and I've only used it once. It's not Pyrex, but seems perfectly acceptable,
especially for a beginner level one.
Also, it's a great deal and comes with all of the hardware required to support it, including an extremely heavy duty ring stand that I am very
impressed with. You can buy the exact same kit here:

Also, the picture on there is kind of bad, so here's a better one that I took:

The first apparatus is ideal, as it can be rearranged to reflux a reaction. This may come in handy later, if you decide to explore organic chemistry.
As thesmug said, I'm skeptical about the quality of that first distillation apparatus, and you may want to get something a bit nicer.
What do you intend to distill? Assuming that you don't live in the USA, Europe has one (or several) standard ground glass joint sizes, and it's best
to buy the most common size. That way you will be able to use all of your glassware together, if the need arises. In the USA, 24/40 and 29/42 joints
are the most common.
Best of luck.

zts16 wouldnt the vapors/liquid come out of the hole that sticks out to the side at the bottom of the condenser?

Im planning to make bromine, nitric acid, acetic acid, sulfuric acid and so on.

That hole is for cold water to go in, so that the condenser can condense the vapours.

No, that hole is the output for the cooling water. I just didn't have anything attached there in that picture.
The condenser that it uses is a Graham condenser, so the distillate runs through the coil, and the cooling water flows around it. The distillate drips
out of the bottom, into the flask.
So far the only thing that I've distilled with it is store bought ammonia, to remove the surfactants. I plan on doing much more with it in the
upcoming weekends though!

oh ok. Also could i use a adapter to close it off at the end so that i can distill dangerous chemicals like bromine?And does that site have tubing to
connect to the condenser? I might buy that (asking my parents for a early b-day right now).

Does it fit with a thermometer adapter?
Sorry for asking so many questions..

The cooling water always goes in the bottom and out the top, so that the condenser is full of cold water.

A thin rubber hose will connect to the glass inlet/outlet.

You may also want to buy a longer liebig, especially for lower boiling distillations, such as bromine, DCM, etc.

The hose probably won't attach to a faucet unless you've got a very thin one. You might be able to jam a funnel into the hose and keep it topped up,
or you might be able to get an adaptor for it.

Oh… oops, yeah, that makes sense… I was doing some weird thing in which I was letting off water from the bottom occasionally and letting more flow
in from the top, now I realize how counter-productive that is.
Thanks!
Also, since I work outside on my patio and don't have access to a faucet other than the garden hose which is usually rather warm, I have a plan to
attach a large funnel (improvised from a milk jug) to the arbor and pour ice water in there, letting it gravity feed into the condenser.

Zts16 how do i get water into the tubing? (I know to use amber or any kind of tubing connected to the condenser) but how do i get it in? faucet? never
mind just the the post above.

It's obvious once it's pointed out- I received a sound mocking in my first year of organic chemistry for not seeing it the first time.

Yeah, a faucet works great if you have close access to it and the water is nice and cold. If the tubing won't connect, you might be able to buy an
adapter that will fit. In the classrooms at my school, the sinks have little threaded pointy adapters so you can work a piece of tubing onto them.
Otherwise, gravity feeding is the only thing that I can think of. Or if you're really desperate, spraying it in with a wash bottle! (:

Copperastic, if you don't have lab faucets you can go to your larger hardware store and purchase a small fountain pump for <$20. Just google
"fountain pump" to see what they look like. You just place the pump in a gallon bucket with your cooling fluid, plug it in and your good to go!
This is my first post, but I have been a (creepy?) lurker here for some time now.

Many faucets are threaded at the end, and you can screw in an adapter which is threaded at one end and has a hose barb at the other - I likely have
some of them somewhere around here. But the simple fountain or fish pump and a bucket of water (with ice if needed) works fine also and saves some
water.
Do be careful, I would advise people working with anything flammable who are new to organic or distillations to start outside or somewhere where
starting a fire is not as bad. I have read about, heard of and created enough fires to know what I speak of, trust me. If you have a stirring
hotplate and use a water or oil bath, it might work OK in a garage or workshop, but if you are trying to boil methanol with a flame, then outside is
really a good idea. Once you have tried things, you will get the hang of what is safe and what is not. I would maybe even try ethyl acetate first,
as it is more useful (does not boil way so fast) and ethanol is a great chemical. Just finding or making acetic acid will be a good first step. It
is very useful and might be a good trial distillation.
