So swim tried the old srv, a little while back and then was distracted after doing all the hum dee lala lala and performing it seemingly without error, it was placed in the freezer.
The vac. distillate was noted at coming over between 102-110c, saf apx the mid 80's to 91-92. Swim seemed satisfied.
however, recently when swim went to check on it it was half frozen. finely formed crystals, and when tipped on it's side there was a small amt that remained fluid.
Before running for help all the FAQ answers were tried, it was redistilled under vac, and a more refined yellow/green fluid came over again, no forerun, only the upper fraction collected and saved, and the same shit happened! frozen!
it seems to pass every other test swim can think of though... smells correct, casts greenish glow under UV light, rootbeerish taste that sort of numbs swims tongue, bp is almost dead on (swim is open to the fact them. may be off by a degree or two).
what the hell? Has this happened to other swimmers? thanks for any help.
