With the proper equipment and training, processors can extract specific compounds like THC. Understanding boiling points of each compound is critical. The entire extraction process takes time, money, and dedication but is well worth it! And with an Apeks Supercritical system utilizing cold separation to preserve the terpenes and other compounds, you can join other customers producing award-winning oils!
Extracted material is free of residual solvents. Nothing is left behind once the extraction is over since the CO2 bubbles away, leaving no trace.
Comparing CO2 cannabis extraction to butane or propane? Don’t forget to include the facility costs for processing with a compressed flammable gas.
Other extraction solvents, such as hydrocarbon-based propellants like propane and butane, hexane and pentane, or ethanol/alcohol mixtures, require additional distillation or purging beyond the extraction process to separate the solvent from the extracted oil. CO2 has a very low boiling temperature and wants to be a gas at room temperature, so it naturally separates from the extracted oil, the same way a soda goes “flat.”
CO2 extractions can be done at temperatures native to the plant, minimizing thermal degradation of the plant material and the extracted oil.
CO2 is readily available and widely used throughout a number of industries. Apeks CO2 oil extraction systems recirculate and subsequently recover 95% of the CO2 used in each extraction.
