Pope Scientific’s 2″ diameter Wiped-Film (short-path) Molecular Stills have become the classic machine in all the legal states and several countries for final purification of THC and CBD at highest purity, quality, yield and clarity, with output of >1 kg/day. Pope’s 4″ and 6″ models are utilized for greater throughputs, (plus larger systems up to 200 kg/hr!). Terpenes collection also possible. Feed and discharge pump systems available. Excellent results are independent of the extraction method used, (SCFE, Butane/Propane, Ethanol etc.), and whether or not winterization and/or decarboxylation has been performed. Distillate product is optically clear light yellow, with the dark residue, chlorophyll, heavy waxes, salts, etc. left behind. Pope Wiped-Film Evaporators (WFE) are utilized for continuous large scale solvent removal, (post-winterization, etc.) as an alternate to rotary evaporators. Custom Ethanol extraction, winterization and filtering equipment offered also. All equipment manufactured in the USA.
