The MK4c from Terpp Extractors comes fully assembled, pressure tested, and certified for the state of Washington and Colorado facilities.
The 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.
The bottom-flood Terpenator© design allows for superior solvent soaks versus 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. If top-flood is desired, the solvent input valve may be easily relocated to the top of the material column. The MK4c closed loop extraction machine can also be modified as a bidirectional system allowing you to flood the solvent from the top, bottom, or both in the same cycle.
