Thanks Art.

Also, I've had a question that I haven't been able to find the answer to (or if I did, I forget what it is).

Does anyone know if, after a naphtha pull, you could evaporate most of the solvent off using a heating mantle/round-bottom flask?  Would the heat cause too much oxide formation for this to be feasible? 

Edit: Never mind.  It seems like their boiling points are too close for a distillation to work well.  Silly me.
