When you are working with large volumes/many batches of extract, a rotary evaporator confers three basic benefits.I want to know why tho...what does that do, that's worth 1300. is it like a medical thing, or does it make some part of smoking that much better?
1) It greatly speeds solvent removal over, say, distillation as typically performed.
2) It removes more solvent than other techniques (keeping temperature constant), reducing the load on the vacuum pump in the next step: purging residual volatiles.
3) It allows for higher per cent recovery of solvent per run, which is a big plus considering how expensive suitable solvents have become.
