Also, you can just save a couple containers, maybe 3?

Have 1 to dump your defat waste, 1 to dump your precip waste. Distill off the defat waste to purity and put in 3rd bottle. Then distill off the precip waste and dump that in the 3rd bottle.

So after a while you can just distill everything and re-use it again brand new. I mix my precip naptha with my re-x hexane. I frac that and just dump the hexane fraction back in the bottle. And the naptha fraction gets to go to the naptha wash bottle.

As far as ethanol goes, I use a sugar wash w/ nutrients and distill my own ethanol to its azeotrope. I can prepare ether with this and I'm set for extracting THC. Lab equipment can be pretty neat some times =]
