I decided to use toulene as my non-polar solvent because it's easy to get it. My question is, what is the best way to evaporate the toluene from the soaked organic material?




Well if your product were a volatile liquid, than toluene's $\pu{110 ^\circ{}C}$ boiling temperature (of the pure solvent at atmospheric pressure) may be dangerously high.


If you aim for a solid of low volatility, evaporate it under the reduced pressure of a membrane pump and gentle warming by a water bath. If accessible, a rotary evaporator is a good thing for this: lower the pressure gradually to about $\pu{70 mbar}$, then increase the bath temperature to $\pu{60 ^\circ{}C}$.
