Purging ethanol with hot plate

Technically if you add enough condensers/cold condenser in a row to your short path you could recover a pretty wild amount of ethanol with your 5L. But I’d say you’re gonna likely Max out at 2-3LPH. Just do what these folks say, build your own. Rotavaps suck anyhow for the price. Ethanol recovery can be done at 5x the rate for the same price in stainless.
