I don’t like xylene. It’s stinky. Boiling it is a fire hazard. But it worked very well for SWIM’s extract.

I guess it all depends on what you're cleaning up. The xylene worked best for SWIM’s DCM based A/B extract. It produced nearly pure crystals in one shot, and tons of them. But they were small crystals. With SWIM’s A/B extract, the MEK:haptane mix produced less results per ml, but far larger more beautiful crystals, however there was also some amber contamination present.

It’s good to have two different options. Now that SWIM has a better idea of how to clean up and crystallize bufotenine, he’s got some other ideas to try. Hopefully a simple tech can be put together soon that starts with seeds and ends with clear crystals in just a few steps.
