need help with some equipment that was given to me

“I’m interested in using a rotary evaporator for botanical extractions. What are some key things to know about its operation and safety considerations?“What solvents are best for extracting alkaloids from plant materials using a rotary evaporator?”


its not your normal small rotary evap its pretty big like human sized water bath

A rotary evaporator is used for rapidly stripping off large volumes of solvent, typically under vacuum. One key datum we need to know is the size of the evaporating flask.

Tbh, judging by the water bath it sounds like it's far too big for the type of extractions normally envisaged here. See:
DMT Nexus Attitude - 2.10 No commercial-scaled extractions and reckless "spreading"

A rotary evaporator alone wouldn't be the first piece of equipment I'd suggest starting a lab with, especially not an oversized one like that. It sounds more like something that would get used for pilot-scale pharmaceutical development. Sell it and spend the proceeds on something more useful.

@Transform I appreciate your knowledge and honesty of the matter and for now ill be using the old fashion poor man way it seems to be working just fine safety first
 
Conceivably, at a pinch, a rotary system could be used for bringing two liquid phases into contact quite thoroughly, without needing to use the vacuum distillation aspect. The water bath as well as the chillers also provide a temperature control option. As previously mentioned, your piece of equipment sounds like it's way too big (like, anything bigger than 2L is getting oversized). This scale mismatch compared to a typical size of extraction leads to losses from the surface area of the vessel alone, and handling could be rather cumbersome, leading to further risk of difficulties.
