Terpp Extractors MK4c Terpenator© is a closed loop hydrocarbon extractor developed and copyrighted by JD Ellis, aka Grey Wolf, previously of Skunk Pharm Research now Pharmgold and built by Terpp Extractors. The MK4c is designed for Butane & Propane solvents.
Terpp Extractors bottom-flood Terpenator© design allows for superior solvent soaks compared to alternative top-flood designs. The design also allows for heat application on the column to recover all the solvent vapors normally trapped in the column through the liquid “overflow” line without releasing unwanted compounds into the collection pot. for a more convetional design, the solvent input valve can easily be relocated to the top of the material column. The MK4c can also be modified as a bidirectional system allowing you to flood the solvent from the top, bottom, or both in the same cycle.
The bidirectional modification is currently under a review process and is not certified for use in Washington or Colorado facilities as well as other states. However, the standard MK4c is ready to go in Colorado and Washington facilities.
