Terpp Extractors has agreed to do CLS testing with MZ12X. Rather than wait for complementary cases from Pure ZHO I bought a couple, $120 out of my pocket, just to see this through.
Weirdest thing, Dr Z (Sang Kim) called me just as I was beginning to compose this post, he's looking for a new partner... well in a couple of weeks he may have some really staunch offers.
Just a guess, but dimethyl ether may be more free flowing at deep sub zero temps than butane...
My sincere thanks to Austin at Terpp Extractors!

Careful with the elastomer gaskets and seals with Dimethyl Ether.
