What is BHO extraction?

Butane Hash Oil, or BHO is the essential oil extracted from the cannabis plant using Butane as a solvent. BHO concentrate can be extracted from fresh or cured material. The result is a mix of waxes, cannabinoids and terpenes.

What cryo-ethanol extraction models are offered by Root Sciences?

  1. CryoEXS 400
  2. CryoEXS 800
  3. CryoEXS 800-Dual
  4. CryoEXS 4000

How does CryoEXS compare to traditional extraction methods?

  • Traditionally, the most common extraction methods used in the creation of cannabis crude oil have been CO2 extraction, light hydrocarbon extraction, and warm ethanol extraction, as shown on the left side of the diagram pictured above.
  • In contrast, CryoEXS, as shown on the right side of the chart above, entered the hemp and cannabis extraction market in 2019, and has since cut the extraction process down from days to hours by utilizing cryo-ethanol extraction (commonly referred to as cold-ethanol extraction) technology.
  • CryoEXS efficiently leaves all lipids behind during the extraction process, which allows processors to cut the process bottleneck down from a few days to just a few hours.
  • Manufactured by DEVEX of Germany, our cryo-ethanol extraction systems provide the benefit of bypassing several steps that must be followed during the other pictured extraction methods. As you can see from the diagram above, this type of cold-ethanol extraction technology offers a much more advantageous and time-efficient solution to the extraction process.

About Distillation

Who is VTA?

VTA is a specialist in thermal process engineering. The company designs and manufactures thin film and short path distillation plants for laboratory and pilot purposes. You can view a VTA laboratory model here.






What is Short Path Distillation?

Short Path Distillation is a thermal separation process characterized by the distilled vapor only traveling a short path before condensing on the condenser, enabling efficient operation with little waste.

What is Wiped Film Distillation?

Wiped film distillation makes use of wipers to spread the feedstock into a thin film, greatly increasing surface area and decreasing residence time – or how long the feedstock is exposed to high temperatures. Wiped film evaporators can use either an external condenser or an internal condenser, in which case they are called wiped film short path evaporators.

Yes, our short path evaporator is fully jacketed to help maintain a consistent temperature throughout the cannabis distillation process.

What is included with your Short Path Distillation equipment?

Root Sciences provides a commercial-scale solution for cannabis distillation. We provide full machine assembly, testing and training to allow you to produce distillate on day one!

What types of extract can the VKL process?

The VKL processes only sulfate-free, pre-processed cannabis oils derived from CO2 (Carbon Dioxide), BHO (Butane Hash Oil) or Cold Ethanol (-40˚C to -60˚C or lower) that have been fully winterized, decarboxylated and devolatized.

What exactly does the VKL system do?

Root Sciences’ VKL extraction systems quickly and efficiently distills a highly-purified, cannabinoid-rich fraction.

The VKL does NOT separate individual cannabinoids and/or remove pesticides.

Are the recovered terpenes usable?

Primarily, only heavy-end terpenes are recovered during distillation. However, these terpenes may reused if desired.

What yield will I see from the VKL?

Individual yields are highly dependent on the material used. However, the VKL system can capture up to 99% of available cannabinoids, and typical yields range from 80-85% by weight.

What potency can I expect from Root Sciences' VKL distillation equipment?

Potency is highly dependent upon the material used, but can exceed 99% total cannabinoid. Our clients report typical ranges in the low to mid 90s.

What is the definition of a nanoemulsion?

An article published by the US National Library of Medicine defines nanoemulsion as a ‘fine oil/water or water/oil dispersion stabilized by an interfacial film of surfactant molecule having droplet size range 20–600nm’. 

What are some key advantages of products made with nanoemulsions versus traditionally manufactured edibles?

At the top of the list, bioavailability of the cannabinoids greatly increases in the human body. (Cannabinoids are the active ingredients in edibles.) When compared to traditionally manufactured edibles and beverages, recent studies indicate products created with nanoemulsions take effect more quickly and deliver more consistent and enjoyable experiences for consumers. Most people also report a much cleaner taste in nanoemulsified edibles and beverages they consume, opposed to traditional edibles.   

What is bioavailability?

In the application of hemp and cannabis infused products, bioavailability is the measure of how much ingested THC or CBD is absorbed into the bloodstream and thus to what degree it elicits an effect on the consumer.  

Does the route of ingestion influence bioavailability?

Depending on the route of ingestion, this can be affected by a number of factors. For example, smoking flower, eating an edible, or drinking a nanoemulsion-based beverage will result in different effects on the consumer. 

Are the nanoemulsions created with our GEA line of equipment water-soluble?

Yes.  Our machines produce water-soluble cannabinoid nanoemulsions for easily incorporating in the manufacturing process of cannabis infused edibles and beverages. 

What types of nanoemulsions can be produced with Root Sciences equipment?

Depending on machine model purchased and other influential operating factors, producers have the option to create clear, high-load, or flavorless nanoemulsions to include in the formulations of hemp and cannabis infused products. 


What are the key benefits to Root Sciences’ nanoemulsion technology in the manufacturing of edibles and beverages?

  1. Our equipment produces water-soluble cannabinoid nanoemulsions
  2. Easily added to beverages and edibles
  3. Improved bioavailability and faster uptake
  4. More precise dosage due to true homogeneous mixing
  5. Create clear, high-load, or flavorless nanoemulsions
