i have a distillation apparatus but i cant really use it.


my round bottom flask only touches a bit of my hot plate which does not efficiently transfer energy. i know i can get a heating mantle but they are expensive. does anybody know of anyway to get around this problem?

btw my shift key is broken so that is why i don't have any capital letters

Put a water/oil bath between the RBF and hotplate.
Both shifts broken?!

I second what fusso says. You can use a metal pot, fill it with water or oil, put it on top of the hotplate and partially submerge your flask in the fluid.

Also, welcome to the forum!

a sand bath can be used for higher temperatures

How competent are you with making basic things? and what is expensive to you?

i don't really know what would be classified as basic, i understand chemistry in theory but am only now getting in practice, i have a low budget since i already spent around $350 on glassware and a hot plate

Besides water and oil, baths of metal beads may also be useful.

Also, how did you type the $ sign without a shift key?

I just touch my round bottom flasks to my hotplate and that has always seemed sufficient for me.
Never had a problem.

i always used aluminum foil as insulator.i wrapped the foil around the flask and over the hotplate like a mary poppins skirt.all the heat escaping the hot plate is directed over and around the round flask.worked awesome and never has my flasks touched the burner.

let me rephrase, can you wire a basic electrical circuit, and cut a soup can with out dying?

If so a 1500w light dimmer from local store, and a mantle from daschem for 33 dollars cad and some wire = veritable power heating mantle for about 50 dollars

If you have access to an old oven then you can salvage the high temp wire and the infinite switch from that but will be less precise then a dimmer

Once wired, the soup can was carefully packed with mineral insulating wool to insulate the live wires and to immobilize them inside the can.

If you want to make a separate build thread a great many of us should be able to help you.

Yea I can do that without dying. Do you use nichrome wire for heating?

Edit: a accidentally uploaded a pic

no need for nichrome wire, on ebay you can buy the already made heating element woven with glass fiber in a cup shape

Heat rises off the hot plate. 80% of the distillations I do use nothing but a centimeter or two of air between the flask and hot plate. If you want to increase the heating efficiency just put a cone of foil around the boiling flask (narrow at the neck and as wide as the hot plate itself at the bottom)

Sometimes they only sell the glass sleeve without heating element (and they count on people not seeing this), so make sure to read the listing before buying. Maybe winding a heating element from nichrome would feasible anyway if you have a glass sleeve.

Same great advice, but have to say I like cyanureeves' characterization a little better :)

Go slow and gentle with your glass wear, but breaking it is part of the learning, when ever practical get two of every thing just for that reason.

Good quality silicon grease goes a long way, I use a type meant for water filters but have found it holds up good to most things.

I prefer sandbaths, no sticky oil on your flask and it absorps chemicals in case of a brake, and you can go above a hundred degrees.

Also the flask won't start floating when it goes empty.

That is the normal suggested solution that they teach you at school.

Clamp it. You are supposed to clamp these things as a safety precaution anyway.

So - yea - oil/water/sand bath on the hot plate is standard. Always clamp it as standard.

If not too late keep the broken pieces, crush to repetitively moderate size (6-10mm) sieve to remove fines and save them as boiling chips. Trust me when I say you will be needing them as you pursue the art of distillation.
