Recystallization Hexane to use?

[thirdeyeopen86]

Hey guys I was wondering which Hexane should I use for re-xtalling?

This one, which is lab grade:

Or this one:

I'm using Vovin's Tek pulling with VM&P Naphtha, recrystallizing with Bestine Heptane, and then I wanna finally purify the crystals with Hexane.

if money is an object, second one should do ya fine.

If you let your crystals grow over several days it'll be perfectly fine.

nice re-x method, i use some pentane isomers, hexane, and heptanes to absolutely astounding results. simply distill out from naptha, use the remaining naptha for defat pulls.

Thanks! No money isn't a issue so much as wanting to make a pure of a extraction as possible. I've never re-x before so I'm excited to see what happens. BTW about how long does re-xtaling take in your experience?
