Citric Acid Distillation

[pewex]

I’m trying to build something similar to this setup:

500ml or 2L

So… plugging the mantle into a temp controller would cut the stir bar anytime the heat was cut. Which won’t work. Near as I can tell @beaker was just using his controller as a digital thermometer with the bare thermocouple between the boiling flask and the mantle. I just stuffed a digital thermometer probe in a similar location.

I know this is not ideal but with 400$ I got from David a 250ml spd glassware kit with stands, cold trap and heating mantle.
I also bought this pump VEVOR Tools | Affordable. Reliable. Home lmprovement | VEVOR Store, hoping to keep the vacuum with the help of the grease, around 150um.
I’m planning to distillate minimum quantities of product, in the range of the possibilities given by the flask dimensions, so less than 125ml, and I already have the 99%isolate.
I’m open to criticism and I wanted to thank you for the time given to help!
