The Clear Choice in Equipment for CBD and THC Distillation

For Cannabinoid processing, including cannabis and hemp oil distillation and terpenes recovery after extraction, Pope Scientific’s Wiped-Film Short Path Molecular Stills are recognized as the premier machines in the marijuana industry. We have led the way worldwide in high vacuum molecular distillation and wiped film evaporation equipment, technology and processing services since 1975. Final purifications of THC and CBD to the highest levels of purity, quality, clarity, yield, and product value are readily performed on Pope equipment.

Scalable from 100 Milliliters/day up to 100 Kilograms/hour

Pope Scientific engineers and manufactures an all-encompassing range of distillation equipment sizes—from small lab duty up to large industrial production units. Our multistage, stainless steel, fully turnkey skid-mounted systems serve major cannabis production installations requiring capacities anywhere from 10 kg/hr up to 100 kg/hr.

Our classic 2″ Wiped-Film Stills [WFE] are found in hundreds of industrial and academic labs, and now have become the most popular post-extraction purification system for startup cannabinoid processing companies. They are typically used to distill from 100 ml/day up to 2 liters/day. Our larger standard glass 4″ and 6″ models are being utilized for greater throughputs and are available for up to 5 and 10 liters/day.

Excellent results are produced, independent of the extraction method used, and whether or not winterization and/or decarboxylation have been performed. Distillate product is optically clear light yellow, separated away from dark residue, chlorophyll, heavy waxes, sugars and salts. THC distillation and CBD distillation produce high value clear shatter or dab, and fine oils for vape and edibles. Terpenes isolation and collection is also possible. All Pope Scientific equipment is proudly made in the USA.

Pope Scientific THC Distillation Equipment Takes It Beyond Extracted Purity

F.A.Q.

  • Is molecular distillation similar to extraction?
  • Are solvents required for the process?
  • What advantages does a Pope wiped film molecular still [WFMS] offer?
  • Is this a fractional distiller, a short path still or a rotovap?

You’ve got questions about marijuana pot distillation. We’ve got the answers…and the solutions.

How It Works

When further post-extraction THC and/or CBD product purity and clarity are needed, distillation is a good choice because the mixture contains components with different boiling points. However, the components are heat sensitive as well as viscous.

The Pope continuous flow-through, (not batch), technique is ideal because it utilizes high vacuum to decrease evaporation temperatures plus efficient wiper blades and short residence time, (seconds), to decrease heat exposure times.

One pass typically distills off any remaining volatile solvents, water and gases, and another pass distills off and collects the main product—normally THC or CBD. Other passes can be performed for terpenes.

Pope Nutsche Filter-Dryers are known and used worldwide for critical high purity separations of liquids and solids; and are now being used in the cannabis industry.

With this separation being a critical operation because it is often the final step in the entire manufacturing process, our Nutsches are preferred—proven for CBD crystalizing isolation to 99+%

In this cannabinoid application, as in most applications, the remaining solid is the valued product—highly pure crystals from reaction and precipitation. This CBD isolate or extract is cannabidiol in its purest form, with additional cannabinoids like THC, terpenes, and plant components stripped out.

Pope’s designs are available in lab bench through pilot plant and production scale, in volumes from 0.2 through 1000 liters.
