This is a shot of D9 THC isolate being peeled off the bottom of my cryogenic sublimation apparatus. Pressure used in this final step was reported as ¾ of one micron nominal. Temperature of oil at this stage was 127° C. This very low final temperature "distillation" as carried out in a cryogenic sublimator. The sublimator is pressed into service not for sublimation at all but rather as an extremely short path device. Utilized thusly the unit represents a true theoretical single plate molecular simole distillation device and purities approaching absolute are possible.
