I still haven't heard from anyone willing to take the 30lb butane and propane tanks EcoGreen sent me for testing, they can also have several cases of left over canned butane. Inland Empire, SoCal. No kids, lol. ;-)
I used it for some extractions, here is one test result:

I didn't distill it.
Would love to take you up on your offer, depending on your whereabouts in the empire. I'd send you a message, but it seems I haven't quite figured out how to do that yet.
Results look righteous, how was taste and smell of the product?
Wait, are the residuals of the tank necessarily tested for by the lab, or do they just test a list of common hydrocarbons used for extraction? From what I can tell there's no space for sulfur or anything mentioned thus far.
Dang. I just ordered a 50#nbutane from evogreen. What's the verdict? No good?
