I keep reading that people are using this Circulating Water Vacuum Pump double duty for vacuum and cooling the condenser, unless a rotovap is different, or I misunderstand. But I suppose even if I used it for vacuum only, then I can recirculate ice water for the condenser separately if need be, with a small aquarium pump and a bucket of ice water.No; you can’t double-duty that one.
The variac is for fine control of mantle heat. I’d buy standard Glas-Col mantles which are non-adjustable, as mantles are wear items.
and Yes that’s the kit!
I was just reading up on variacs and Glas-col, and I see the importance of not over heating ethanol but damned we are talking some serious money to buy lab grade stuff! !! Lot's of used Glas-col on EBay. I did see you can actually make a home made variac from a wall dimmer switch some how! I also read a poor mans way to go is an oil bath, which that's what I used on my 1st experiment.
Ugh, so much to learn, so much to do, which does makes it interesting... I feel confident about your glassware choice. And the stand set is probably ok. Vacuum pump will work...Heat source, maybe I better keep reading, or I have my trusty oil bath.
Oh, and maybe I need a small magnetic heater / mixer for warming and mixing distillates / rosins, final cooking of oils, etc.
