What is the all out best butane for BHO?

Anyone heard of this stuff? Saw it on CL and never heard of it.

I was reading an article in High Times titled "The Butane Cowboy". It was about the creator of Puretane. Has anyone tried this stuff or done a clean plate test? They say 99.9998% pure, triple refined n-butane, 9 times filtered and then put into seamless cans that don't have any machining oil residues. I copied the can photo from their website: https://www.puretane.us

Yes, Puretane donated a couple cases to Skunk Pharm Research for testing and I pre-distilled it, to find it still has some MO.

After removing the MO, we extracted a Mk III run with it and got good results. I would use it, but I always pre-distill, regardless of whose gas.

Here is how Skyhighler's tests rated it in the pack, as far as how much MO:

A new player on the block in Oregon, named Apis Labs, whom is supplying Praxair 99.5% Instrument grade n-butane and n-Propane, which deposited minimal MO distilling 48# from two LP-5's bringing a new Mk VB on line, so I sent a tank to my third party state certified forensic lab for analysis. I will report back when I see those results, but the n-Butane goes for $300/LP-5. Until their web site is up, [email protected] is how I contact Jay.

99.5% N-tane is where it is at if you can get it for the right price

Sorry I know this post was created forever ago but noticed some individuals actually thought Ronson butane was good for anything. I have to laugh. If there were ever some crap butane it's Ronson. I'd rather use Korean mystery butane than Ronson. Also if you want to clog your torches in the shortest time that would be the stuff to use. I can confidently say this due to numerous times past experience with their crap as a last resort thinking maybe it was a bad batch or something. Not a couple times. .. Enough times where I should have gotten a clue to stop using their stuff even in case of emergency.

Kinda new to BHO.
Was wondering if anyone has ever used Emzone butane? Came from Canadian Tire. Wasn't my 1st choise, just ended up with it lol
(getting some Calabri soon anyway)
End result after vac purge is super clear yellow and like glass, with awesome flavour and aroma.
