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.  […]

Graduate from Short Path to Spinning Band Distillation

Short Path Distillation – Just Getting Started Short path distillation is an entry level system for making THC distillate from crude extract.  Its simplicity and low cost make it attractive to those new to making distillates.  Making THC distillate with the short path is exciting at first but in time the excitement can turn to […]

Compare Spinning Band Distillation with Short Path Distillation

Short Path Distillation Short path distillation is an introductory distillation technique sometimes used in labs in their start up phase. Short path produces usable but lower quality oil often in the 80% cannabinoid range after 2-3 passes. A common problem during short path operation are vacuum leaks which lead to degradation and dark oil. Spinning […]

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 […]
