Industry Leader in Laboratory Distillation Equipment

Butane Collection for True Boiling Point Distillation – ASTM D2892 Butane is a component of crude oil that boils well below room temperature.  Its low boiling point requires special receivers to prevent loss of butane from the system. The receivers are cooled with dry ice or a cold finger style cooling system. There will either […]

Vacuum Pot Still (VPS) The vacuum pot still distills crude oil residue from 370 ºC up to 565 ºC.  D5236 is the ASTM test number. It is most commonly used to distill the residue from ASTM D2892 true boiling point test. There are four sizes of distillation column shown in the table below with corresponding […]

Lab-scale Crude Oil Distillation Distillation of crude oil in the laboratory models what happens in the refinery.  The results of the lab-scale distillation predicts the quantity and quality of each distilled product from the refinery.  This information is used to choose the best crude oils for a refinery at the best price. The refinery distills […]

True boiling point distillation has distillation column packing that has 15 theoretical plates of efficiency. Many different types of packing are currently available. There are two main categories of packing. Structured and random packing. Pro-Pak The most popular type of distillation column packing used is called Pro-Pak. Pro-Pak is made by the Cannon Instrument Company. […]

THC isomers and reactions products, CBN, Delta 8, 9 and 10, HHC

THC Oxidation to CBN CBN is the oxidative degradation product of THC. It is more stable than THC due to its conjugated structure.        THC- Delta 9                                                     CBN […]

Compare Spinning Band Distillation With Wiped Film Distillation

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 […]

Cannabinoid Distillation – What Comes Out of the Spinning Band System?

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 […]

What are these “things” on my 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 […]

The spinning band distillation column has a vacuum jacket (like a thermos) to minimize heat loss through the distillation column wall.  The evacuated jacket disrupts heat conduction due to the lack of air (only 10-7 mmHg !). The vacuum jacket has a silver coating on the inside to reflect any radiant heat. Combined with the […]

Spinning Band Distillation – High Purity THC Distillate

Spinning band distillation Spinning band distillation can produce distillate with very high THC/CBD concentrations.  Over 90% THC concentration is typical for a first pass. Some customers are routinely producing 98%+ cannabinoid distillates! How does the spinning band do it? Distillation separates components by their boiling points.  This is commonly referred to as the “efficiency” of […]
