Cannabis Oil Products - A Time Line

How are THC/CBD products such as vape cartridges, dabs and edibles created?                 Grow It It all starts with “the grow”.  Most cannabis grows are done in a controlled room. Light, water, temperature and other environmental factors are carefully regulated to maximize cannabinoid production. Cannabis plant genetics are […]

Fractional Distillation versus Simple Distillation

Simple distillation Simple distillation is a single stage distillation where a liquid mixture is boiled and the resulting vapor condensed. Wiped film and short path distillation are examples of single stage distillation. Simple distillation can provide a moderate improvement in purity. It is useful in situations where you are attempting to separate compounds with very […]

No Leaks - No Streaks - No Smell

Tired of chasing vacuum leaks, streaks and residual terpene smell in your THC distillate? Try spinning band distillation on your crude extract.   No leaks Stop chasing vacuum leaks and using globs of messy vacuum grease (vacuum grease is not food grade).  Spinning band distillation uses o-ring joints that are vacuum tight with every use.  […]

Wiped Film and "The Split"

Did you know that during a decent first pass in a wiped film that 50% of your starting material can go to waste?   The 50/50 split is the perfect example of the low-efficiency of a wiped film. If your crude extract is 50-70% cannabinoids, then how can 50% of the material be waste on […]

Compare Spinning Band Distillation With Wiped Film Distillation

Spinning Band Distillation Spinning band distillation offers a high efficiency distillation column that can produce 90+% cannabinoid distillate in a single pass. A single pass distillation means you’ll spend a lot less time distilling.   Operation is streamlined. The spinning band acts as dynamic packing.  Condensed oils are pumped back down the column while pure vapors rise […]

Ethanol for Easy Cannabis Oil Handling

Ethanol for easy and complete cannabis oil transfer Extracted oil is viscous and sticky.  It requires heating in order to transfer it and valuable residue left behind in the original container. If you have ever run a rotovap, you will know the last bit of solvent always takes the longest to remove. The oil gets […]

The Myth of Continuous Wiped Film Distillation

Wiped film (WF) distillation is intended to be operated as a continuous process.  Continuous processes have the advantage of running nonstop.  Oil is fed in one end and product comes out the other end. But wiped film for cannabis oil is being operated as a multi stage batch process which is on the other end […]

Cannabinoid Distillation - Fewer Passes Equals Faster Distillation

Spinning Band Distillation Fewer passes = Faster distillation + Higher Purity + Easier Cleaning   Throughput for a wiped film system is slower since: 3 passes are required 3 cleaning cycles are required decarbing is a separate step oil must be stripped of ethanol before distilling final purity is less than with a spinning band system […]
