Refining highly purified Delta 9 THC

This is how I take dispensary grade extract testing nominally at 60% THC and refine to near absolute purity. The medicine vaped fresh out of the sublimation apparatus is substantially pure D9 THC and is extraordinarily potent in this state. Degredation begins immediately upon exposure to atmosphere and continues rapidly changing the compound to red over time. In a few weeks the compound in the video was ruby red. Degredation of the THC is halted if stored under deep vacuum but any other method including freezing the compound does not stop it from turning red at a rapid pace.
