Purest butane with least amount of impurities?

It's been nearly 5 years or so since I was blasting. Back then my favorite butanes to use where Newport, Calibri, or Lucienne. I'm wondering what's the best butane on the market for BHO now a days? I've never tried this new Puretane made in America before. Newport doesn't seem near as easy to find anymore. So I'm thinking of doing a mirror test on a can of this Puretane.

So what's the good word on clean butane now a days guys?

I prefer 99.95% pure Instrument Grade and when I measured it I found it to be 99.99% pure. After predistillation it measured 99.998% pure with regard to molecules greater than C-4.

Typically a 70:30 mix of n-Butane and n-Propane to extract below -50C, though we've used 50:50 mixes, and mixes that included Isobutane.

Where might I find some of that?

Do you like to order their 70/30 mix, or do you make your own mixture of butane and propane? Also you say you extract below -50C. I know that pressurized butane comes out much colder than that. I can get my material down to -80F in a small deepfreeze with dry ice. How do you extract at -50C or below?

I purchase the 70/30 mix.

I've used either dry ice and alcohol or LN2 to lower the temperature as I pass the LPG through either an emersion or a counter flow heat exchanger.

"Emersion or a counter flow heat exchanger." Are those parts of a closed column, or closed loop system? I've only ever open blasted in the past. But I think I'm ready to upgrade my BHO equipment.

Locally I get it from Apis Labs in Eugene, OR, who delivers and ships. https://apis-labs.com/

I'm so stoked that you led me to these guys! With all the different alcohols they offer, which do you prefer using for winterization? Also for RSO extraction? I was thinking the 200 proof ethanol. But would much rather go with your more experienced suggestion! You the shit Dawg or Wolf, leading the pack around here!

They are part of a closed loop system. The solvent passes through the heat exchanger on the way from the storage tank and the column of material.

There are also heat exchangers on the recovery side to lower the temperature of the stream for passive recovery or for pump exhaust.

Yeah, they've been a good vendor for me and the customers that I sold equipment to.

I prefer ethanol for extraction and winterization, using QWET below -50C. I get the lower temperatures using either dry ice or LN2.

Thanks for the good thoughts and appreciation, but as you know, you can't lead or herd cats, which is much like the cannabis crowd. I'm just sharing one way to do it and learning myself.
