I am no longer affiliated with Skunk Pharm Research and have not used my email account there since August 2017. Have any of you attempted to contact Graywolf at [email protected] or [email protected] after 8-7-2017 and received a reply from someone purporting to be...

Solly The Alchemist Resource is temporarily closed due to pending legal issues. More later when those are resolved. Our first blog site was Skunk Pharm Research until about June of 2017. Here is a link to Wayback Machine archives for Skunk Pharm Research...

We extract the rest by other means. Usually vegetable oil, BHO, or QWET.

In my experience, the faster you can get the solvents out, the more higher boiling point constituents you can retain, so run my pump continuously. The instant you shut off our pump, the pressure starts rising. I use a 100% duty cycle pump. Consider introducing N2 instead of air.

From the balance of the posts, I can see that this was trim. The color also suggest older drier material. How old and how dry? What was the extraction process? How was it winterzed? What type and purity alcohol was used for winterization? How was it filtered after winterization, using...

You can also simply throttle the pump, instead of turning it off and on. The vacuum pump isolation valve between the pump and the chamber can be closed partially to affect the needed flow. Our ovens have vacuum controls, so we don't turn the pump off, we adjust the vacuum level. Typically...

I usually extract the rest of the concentrate from the material using QWET or BHO techniques.

The column is heated after extraction is complete. I close off the column drain and vent at about -10/15"Hg and open a separate port to the recovery pump, so as to recover it separately from the collection pot. I then switch the column heater three way valves and direct the flow in a loop...

My design floods from either direction and a bottom flood gives more even wetting and vents vapors better. The top rinse reduces what is left behind.

We don't put DI slurry in the sleeve, we simply freeze the column of material to -18C/0F and use LPG between -30C and -50C. The material stays frozen during the process and we open a three way valve to flood the column jacket with 150F water at the end of the cycle. T The 3 way valve allows...

As the terpenes and other solvents leave, cannabinoid crystals form around points of nucleation, and become points of nucleation for grain growth. Less wax and fine dust to nucleate around will make the shatter more stable.

Absolutely. For starters you can remove the mystery oil before extracting, and you can finish in Cotton Candy state, which already has low residual solvent.

With a distiller's license, it isn't tax free or illegal to the gubs, and with all the state fees, the drugs aren't tax free either. Be assured of both death and taxes............

As they say, location, location, location, but now add to that Distillers license, Grow license, Extraction license...................... With location all three are possible by sending money to the right state and federal government agencies. Sale of alcohol falls directly under the Feds, so...

Sadly, they picked Heptane because it is heavier, but close to the boiling point of Ethanol, and forms an azeotrope with the alcohol, just to make it not easy to dodge the tax man.

A student brought some shine from his 7' compound refluxing still, and we did a QWET extraction with it. The extraction had a nice amber brandy color, so we cut some 60% with distilled water and passed it around. Actually a nice flavor, which combined the flavor of shine with that of cannabis...

Pharmer Joe sometimes uses n-Heptane C9-H20 in his processes where the end product gets fractionally distilled into Clear. Heptane is relatively easy to separate under low vacuum levels, with precise heat control. Clear distillate, is however no longer a carboxylic acid, so the long question...

n-Heptane is a 9 carbon chain simple Alkane hydrocarbon with a boiling point of about 98.4C/209.2F. Ethanol boils at 78.4C/173F, so most of the Heptane will remain after it is boiled away. Elevating a cannabis concentrate above around 57.2C/135F starts to accelerate the decarboxylation...

May I add that a TRS-21 would work for filtration as well, but the piston rings would be running dry and life would ostensibly be short.

To his discredit, Graywolf based his statement on how low the 1400 series will pull, based on rating of 10-3 published on line, but in reviewing Welch's factory ratings, note that they say 10-4, which is good. Our borrowed 1405 didn't pull below 100 microns, but was used, we didn't optimize the...
