Quote: Originally posted by Pyro  | you get a hotplate with temp. regulator. I got one and it cost a little less than a normal one.
just put the supplied thermometer on the plate, and set it to whatever temp. you want |
If you are working in a round bottomed flask (what is the only what could be heated as we know....), then just a tiny surface of your flask will
contact with the hotplate and the rest, 99% will contact with air what will simply go away and won't heat up your flask.
Oil is good, because it heats up easily and your flask surface is easily contacted with it.

The first time when it will break you will be really surprised. Always use round bottomed flasks and not Erlenmeyers.
