Pure CBD is not a liquid, it's a solid. By applying various purification procedures to gumoleoresin high in CBD you eventually reach a point where you can successfully apply recrystallization to isolate it even further. Have you ever made Sugar Rock…

I purchased a diaphragm pump to handle multiple filtration vessels at a time, throughput makes it worthwhile. I typically filter 8-24L of solution a week. You could probably get a fairly good deal on 2 head vacuubrand diaphragm pump that would last …

I am using a vacuum oven from Across International and oil pump. Vacuum is close to 29.95 Hg. I was trying a different temperatures from room to up to 115F. Keep oil there for 1 day, 2 days. Result is still 5000-5600 ppm.
I've tr…
It should definitely, definitely, definitely not have that much Ethanol in it after the vacuum oven. The variables you're operating your equipment under are insufficient. Are you using a rotary evaporator prior to putting it into the vacuum oven to …
I collect into stainless steel vessels at the moment. Have a lid with a hole to allow CO2 to disperse as I'm collecting, but otherwise it goes into a pre-tared vessel that has lab labeling on it indicating relevant processing details/variables and t…

@ThomasWR Supercritical water isn't steam. Water isn't called the universal solvent because it has the ability to universally dissolve, it's because water dissolves more chemicals than any other liquid.
Interesting abou…
@FlashThunder Not water. Steam. That's why they call it the universal solvent. I was talking to an engineer recently about high pressure water extraction, he seems to think that the Palm Oil processors are eventually going to move in when we've reac…
Also, re: the OP, yes you can apply a standard formula to any known value of cannabinoids to accurately dose liquids. The test results themselves are represented in mg/g in order to facilitate that.
Aye, as @Heylo said, we do not recover our CO2 at all as the risk of pumping back into DOT cylinders is not something we are comfortable with. CO2 is low cost so we don't worry about reuse.
Distillation is a process, not a product. Distillation is a process used for purification, not creating a different product. Simple distillation gives you clean drinking water. Molecular distillation gives you clean compounds within a given degree o…
As we only run a single shift I am able to shut my compressor down for 8 hours in between runs, after which I drain the condensate from the tank before beginning again. When we were running 3 shifts we drained the condensate as often as we could, bu…
