So when working in areas without freezers/electric heating, I'm thinking how to adjust the STB technique for it, and general ideas I've had.
I'm thinking something like:
To keep the reaction warm placing the reaction container into a bath of warm but not boiling water in a large pan only when doing the pulls (is it necessary to keep it warm otherwise?)
For freeze precipitation, could a dry ice/acetone bath or just packing dry ice around a jar of solvent work instead of a freezer? If you can avoid freezing the naphtha I'd imagine it to precipitate very quickly and cleanly. Would any fats also precipitate easier doing this?
If so, would the technique in the large scale extractions thread work as in mixing the laden solvent with acidified water, discarding the solvent, basifying then adding the solvent again work at this point?
Also, an interesting phenomenon that has been noted: with the STB tek when the basified mhrb jar has been left in cold conditions (of approximately 10C), many crystals were seen to have precipitated on the surface of the liquid, could this be a viable method of extraction with the appropriate methods? As far as I understand it the liquid was fully saturated with DMT and thus the excess precipitated so there was still quite a lot of dmt in the liquid but using only water and naphtha it could be an interesting low-tek extraction.
I'm also interested in extractions with totally natural materials but with the stb format, for example distilling pine/other plant resins to use as solvents, I know limonene is used but for something that can be easily grown/distilled in european countries I do wonder if pinene can be used?

as the naptha evaps off DMT is left behind on the surface where the naptha turns to gas. So I would not be suprised if it was DMT crystals that formed when the object wasnt disturbed over a period of time.

also, at one piont that might have been hot np, now its cold...

dry ice should work to cool np to freezer temps, not sure why acetone would be needed??

the idea being that acetone would get much colder form the dry ice and cause the FP to happen real fast.

i know i saw a guide in a maxim magazine one time

id love to be able to fp in 30sec about how to make an instant beer can chiller with a can of compressed co2 style computer duster(co2 not chemical crap)
