terpenes derived from cannabis

Tips For Successful Cannabis Terpene Distillation   Refined cannabinoids such as THC or CBD are some of the most commonly sought after compounds when performing a vacuum distillation process on crude cannabis extract. However, non-degraded terpenes can also be collected from certain material using properly configured cannabis distillation equipment.   In order to successfully distill […]

cannabis distillation 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 […]

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 […]

micro spinning band distillation

Very small amounts of crude oil (7 – 100 ml) can be distilled with the B/R micro crude oil distillation system.  The spinning band with a maximum of 15 theoretical plates can collect a number of fractions with good separation.  Spinning band has low hold up and very high free space.  This makes spinning band […]

Mini Crude Oil Distillation

Distilling small samples of crude oil  100- 1000 ml   Distilling small samples of crude oil can be a challenge.  The “hold up” in the column packing makes true boiling point, D2892 distillation column impractical    Traditional packed column systems have a lower limit of about 1 liter sample size.  B/R developed the Mini-Crude Oil […]
