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 […]

Vacuum Pump and Cold Trap

Vacuum pump oil contamination can prevent a distillation system from reaching low vacuums (0.01 mmHg) ideal for THC and CBD distillations.  Sometimes terpenes can sneak past the cold trap and spoil the vacuum pump oil. A little bit of contamination can cause a lot of havoc in a vacuum pump. Here are a few tips […]

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 […]

Make high quality THC distillate

Many people unfamiliar with the nuances of cannabis refinement often believe that a pass (or two) of crude extract through the proper cannabis distillation equipment is all that’s required to produce a high potency Δ9 THC distillate product. While it may be possible to distill mystery cannabis crude extract into 95% THC with short path […]

Before you read this very cool hack please understand that there are more than a few ways this can go wrong.  This blog post does not purport address all the possible safety concerns associated with its use.  Consult your safety officer for full professional guidance. High purity THC/CBD distillate will be very viscous. If it […]

How would you like to go out for lunch while your distillation system churns out high potency THC distillate.  It may seem like a dream but it’s already happening.   Automation The B/R Spinning Band distillation system already comes highly automated.  There’s no need to sit in front of it all day.  Operators are free […]

crude extract preparation

Various types of crude cannabis extract can be successfully distilled into high purity cannabinoid distillate. With that in mind, it’s critical that the crude always be properly prepared prior to a vacuum distillation process. Depending on the type of extract being distilled, this can include one or more post-extraction steps, such as:   Rough particulate […]

Crystallization

Delta-9-Tetrahydrocannabinol (THC)  is a naturally occurring isomer of THC found in cannabis plants.  It’s psychoactive effects are well known.  While delta-9-THC is the most abundant isomer of THC, there is interest in the lesser studied delta-8-THC isomer.   IUPAC Naming Convention The diagram below has numbered positions on the top left ring structure.  If the […]

Optically clear THC distillate

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.  […]

carbon for scrubbing cannabis oil

Carbon scrubs and other filter media for cannabis oil extracts   Carbon scrubs can be used to remove color from cannabis oil extract and THC distillate.  Other materials are also used as filter media such as diatomaceous earth, fullers earth, bentonite, kaolinite and alumina silicate. While filter media may remove color from cannabinoids, it may […]
