      will meth freebase come off with toluene in

a vaccuum assisted rotovap? Toluene does have quite high bp. so I am worried that in the rotovap, the meth freebase will distill off with the toluene?

      bps are very different

so long as you are not pulling too low a vacuum you should be ok.

what type of pump are you using and what vacuum does it achieve?

      Methamphetamine boiling point

The boiling point of methamphetamine at atmospherical pressure is 209-210°C, so it is very easy to separate from toluene, as long as you do not use excessive vacuum and heat.
