best butane to use?

[CF89]

What’s this deal with Colbri? I’ve been using colibri London butane, and getting it easily, everywhere, in Alberta for the last 15 years.

Just got another dozen last night.

I did notice the caps are white now. Used to be blue. Weird

Apparently London and colibri are two different things? I always thought they were the same.

I swear it used to say colibri on these London cans

Open blasting was out for me after the first time... About 5 years ago I picked up a TE-175 off Ebay . I also bought an extra te-175 tank.. That gives me a charging tank and a empty recover tank..
I have a small 5 cu' freezer in the shop. Cut a hole in the top of it to feed the recovery tant hose.. Next to the freezer is a shop bench... On the bench is a 5 gal vacuum pot that is filled with 110*f hot water.. [vacuum hole pluged.] I bought the heating pad for the bottom of it.. After extracting a load,the extractor is submerged in the hot water, the empty tank is the freezer. It takes a 1/2 hour to extract 60 grams. Then I get to reuse the clean butane over again.
I run the butane through the empty extractor the first time. Distilling empty leaves any mystery oil, and the propane propellant in the extractor.. There is always a film of some oil, the propane I vent off to the outside. The gas I buy by the dozen off amazon.
The extractor does a great job, but it's just to small for me.. I'll be putting it up on eBay next month for $1100. good info here. http://www.tamisiumextractors.com/

since Colibri is out of business whats the next best butane to use?

Since the market has shifted a bit lately, many people have moved toward brands that offer multiple stages of filtration to ensure there is no mystery oil or residue left behind. Look for cans labeled as at least 5x or 11x refined. High-purity butane is non-negotiable if you want to keep your end product clean and safe.
