Make THC distillates with 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 […]

distillation for cannabis oil cleaning

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 […]

equipment for wiped film

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 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 […]

Cannabis oil extraction

Cannabis Oil Extraction – Crude Oil Extraction   Consumption of cannabis has shifted over the years from smoking the plant to the use of concentrated cannabinoid oils.  Vaping, dabbing, and edibles are becoming the most popular ways to use cannabis oil. These oils which are rich in THC and CBD are made by extracting the […]

wiped film distillation for THC distillate

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 […]

THC Distillate Fraction Collector

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 […]

Bellows in a spinning band distillation column

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 […]
