CO2 Extraction
Carbon Dioxide (CO2) extracts are made by passing liquid or supercritical CO2 through cannabis tissues at high pressure, then reducing the pressure to separate the extract from the CO2. It’s also become one of the most popular new ways to extract pure, high-CBD cannabis oil from the cannabis plant. Both subcritical and supercritical methods have become beloved by the medical and recreational cannabis industries – and the people who buy from them.
CO2 extraction can be fine-tuned to get the best possible finished product. Depending on the specific temperature, pressure, and duration of each extraction run, the resulting extract can vary in colour, viscosity, and content of cannabinoids, terpenes, waxes, and lipids. The extract can then be further processed depending on its consistency and the intended form of the end-product.
As a safe alternative to many hydrocarbon solvents, and boasting exceptional opportunities for tuneability, carbon dioxide has become one of the most widely used supercritical solvents in the industry.
