can I use a rotary evaporator to produce distillate?

if i properly winterize after an ethanol extraction, can i produce high quality distillate in a rotary evaporator without having to run it through short path distillation after? can i essentially perform short path distillation in the rotary evaporator without having to buy more equipment?

thanks!

That depends on your understanding of the process.

I believe there is decent evidence that you can perform that trick with the addition of a toaster oven.

Chances are you’ll need more vacuum pump then you currently own.

You might could skip the toaster oven with some creative rewiring of the temp controls.

No you cant. Not easily atleast

I do actually have a heating mantle and larger vacuum pump. with a few modifications to my rotary evaporator set up, It seems like i could pull it off without having to buy or build an entirely different distillation set up. thoughts?

The condenser + vapor path + sizing is gonna make this thing real awkward.

Technically feasible. Yes. Practically? No.

or is there some crucial step or difference im missing all together?

You have a mantle and pump then just hit up @david. His glass is good and a great price.
If this was something that was easily doable wouldnt you think everyone would be doing this then?

Full glass setup can be found for around 600

The condenser is not ideal. But if you can run it at 150C all the bits you don’t want should pass it by. If you’ve got a mantle, a decent pump, and extract you don’t mind losing, then by all means test your knowledge of the problem.

Is it even safe for the roto to be brought up to those temps? Id be worried about melting something

I wouldnt think a rotovap can handle low vac depths.

That was my next thought

Point at the bits that worry you…

In the case of my liitle bucci, i would absolutely lose this bit…

The glass and Teflon is all up to the task, including vac depth. Unless you’ve got something really exotic sucking on it

im now starting to realize that i can just build a short path system with my existing equipment if i just order the glassware and a few bits. I really appreciate all the help!

Have you ever tried riding off into the sunset? It’s a horrible idea. Can’t see a damn thing :face_with_hand_over_mouth:
