Supercritical CO2 extracts different molecules from the plant as it is pushed through the machine.
EXTRACTION
Unlike other solvents, once CO2 becomes a gas, it leaves no residue and does not change the chemical
composition of the oil, making the process highly effective.
CO2 extraction is a scalable process. By scaling the pumps, heat exchangers, process piping, and the fraction
collectors appropriately, whether the machine contains an 18L or 1650L extraction vessel, the solvent to feed
ratio can be kept and achieve 90+% extraction efficiency in as little as two hours
PURIFICATION
CO2 purification can be used to purify individual cannabinoids for subsequent blending with plant extracts to design specific cannabinoid formulations, and ensure that batch -to-batch reproducibility is achieved.
CO2 Purification can be used to remediate THC from hemp extracts. The extraction process not only concentrates CBD from, but THC as well.
The THC can be removed and the rest of the cannabinoids can be collected to maintain the original profile minus the THC.
CO2 Purification can remediate pesticides from contaminated feedstocks. One of the most commonly used pesticides, myclobutanil, can be easily removed using supercritical CO2 chromatography.
The CO2 process-scale chromatography flashes CO2 back to a gas and leaves the extracted fractions in a much smaller volume of ethanol (typically 2-4%) which can easily be removed to recover the cannabinoids
CO2 purification uses CO2 as the solvent and a chromatographic column to safely and purify target cannabinoids.
Scale up to Certified Processor
Our cGMP tolling services allow our customers to increase their competitiveness without the heavy expense associated with capital equipment while minimizing costly downtime related to equipment manufacturing, installation and training. Our facilities offer industrial size equipment using Supercritical CO2 extraction process to obtain the cleanest cannabinoids, including CBD. Hemp is often contaminated with heavy metals and other dangerous substances. These plants have the ability to accumulate toxic compounds from the soil, so in order to obtain pure CBD oil, special cleaning techniques are crucial: the supercritical CO2 extraction is the only method that guarantees the complete removal of heavy metals and toxins organically. The yield rate using Supercritical CO2 extraction is as high as 95% compared to the traditional extraction methodologies.
