Industry Leader in Laboratory Distillation Equipment

Cleaning a B/R spinning band distillation system couldn’t be easier. Just distill some ethanol to dissolve any residue left behind in the boiler, distillation column, fraction collector and receivers.  No need to disassemble the distillation column in order to clean. For cleaning after a run, just load a boiling flask with ethanol, launch the automatic […]

The Myth of Continuous Wiped Film Distillation

Wiped film (WF) distillation is intended to be operated as a continuous process.  Continuous processes have the advantage of running nonstop.  Oil is fed in one end and product comes out the other end. But wiped film for cannabis oil is being operated as a multi stage batch process which is on the other end […]

Recycling Ethanol from Cannabinoid Distillation, Extraction and Winterization

Ethanol Ethanol is its pure form can be quite expensive due to taxation. Denatured ethanol is cheaper but is not food grade due to the chemicals added to prevent human consumption(methanol, isopropanol, MIBK, jet fuel). While some protocols call for the use of 200 proof, many times 190 proof or 95% ethanol can be used. […]

B/R is the only company in the cannabis industry using a stainless steel cold trap. Why would you use glass (an insulator) as a material for a cold trap?  It is horrible at transferring heat/cold.* The condensing surfaces in the B/R cold trap are made of stainless steel which has 10 times the thermal conductivity […]

Software and Automation for the Distillation of Cannabinoids

Automate It! The B/R 9200 spinning band distillation system is automated.  Shouldn’t everything be automated? Automation takes the guesswork out of distilling and reduces operator errors.  Get higher quality product and avoid costly mistakes.  Even monitor the distillation remotely. Automatically control: Heating Condenser temperature Reflux ratio Vacuum level Temperature range for fractions Spinning band Automatic […]

NRTL Safety Certification for distillation of botanical extracts

The B/R 9200 distillation system is has a been listed by a Nationally Recognized Testing Laboratory!  We’d be happy to supply a copy of our certification upon request. Is your equipment certified by a Nationally Recognized Testing Laboratory? This industry grew so quickly that many uncertified products have infiltrated production facilities. NRTL Safety certifications are […]

Cannabinoid Distillation – Fewer Passes Equals Faster Distillation

Spinning Band Distillation Fewer passes = Faster distillation + Higher Purity + Easier Cleaning Throughput for a wiped film system is slower since: 3 passes are required 3 cleaning cycles are required decarbing is a separate step oil must be stripped of ethanol before distilling final purity is less than with a spinning band system Wiped […]
