Large scale BHO extractions

22 posts in this topic

I've been testing out my new extractor at full bore. It's got 196g and is producing some nice clean product.

Just found a source of ultra-pure n-butane. Not the shit for cookers, or the slightly cleaner shit for lighters, or the even cleaner than that stuff used for refrigeration, but the ultra pure stuff for calibrating lab equipment.... and doing BHO extractions of course... :yes:

I was reading the bit about butane on skunk pharm, and it mentioned R600 grade butane, used in refrigeration, as being purer than what most of us use. So I did a trawl for R600 refrigerant. I know a guy who's building a catamaran with a custom refrigeration system built into it which he's designed and built himself. He must have had to buy the refrigerant from somewhere. So I had a look and found Intergas (http://www.intergas.co.uk/nbutane.html is their info sheet on n-butane)

N-Butane (C4H10)

DESCRIPTION: At room temperature and atmospheric pressure, n-Butane (C4H10) is a colourless, flammable, relatively non-toxic gas with a characteristic natural gas odour.

TYPICAL APPLICATIONS: n-Butane in its purest form is used for the calibration of instruments, and also as an intermediate in the manufacture of aviation fuel.

They do 5kg cylinders with standard fittings, but I bet it's not cheap. I'll have to put on my posh voice and phone for a quote...

im toying with one of those just for the butane recovery i heard closed loop makes quite crappy oil , that really needs a dewaxxing or winterizing stage to help clean it up . i think its because of how they keep passing the tane over the trim

1800 dollas is abit of a gamble to find it makes shit oil lol

That is very true. It all looks a little.... breaking bad, too. Not sure I'd want to get busted with it. They might get the impression I'm taking it a bit seriously. lol

I hadn't, very interesting! Cheers for the link. It does mention the extraction of cannabis oil specifically. Has anyone here tried a CO2 extract?

Funny, with the exception of the bit about CO2 being non-flammable, all the rest applies equally to butane, I've learnt through the course of a sleepless night: Non-toxic and approved for use in food products by the FDA. Who'd have thunk it?
