Ever wonder how THC/CBD products such as vape cartridges, dabs, and edibles are created? Read on to learn more about the cannabis oil products timeline! 1. 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 […]
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 […]
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 […]
No Leaks – No Streaks – No Smell
by PaulTired 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. […]
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 […]
Keep it clean. High quality THC distillate should be odorless. It doesn’t take much terpene to give a whole batch of an off smell. Proper cleaning of the distillation system between batches will get rid of any lingering terpenes after distillation. Clean the Distillation Column in Place With spinning band distillation, ethanol can be distilled […]
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 […]
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 […]
Spinning band distillation separates the cannabis oil extract according to the boiling points of the components. Mono-terpenes have the lowest boiling points, so they are collected first. They can be found in the cold trap receiver due to their low boiling points. Residual ethanol is collected next in the fraction collector followed by the higher […]
Those “things” near bottom of the spinning band distillation column are called bellows. They function as a flexible expansion joint. Glass is normally anything but flexible and these bellows are engineered to allow the expansion and contraction over the length of the column. Distillations start at room temperature and goes up to the distillation temperature […]
