A method used by the finest companies in the world, CO2 extraction or Supercritical Fluid Extraction (SFE,) is known for being the most effective way to extract beneficial essences from plant matter. This method is not only used for cannabis concentrates but is also used to create pure essential oils and to strip out or separate different elements of botanicals. Popular products manufactured using this method are: herbal essential oils, hops for beer, high-value pharmaceutical precursors, and decaffeinated coffee.
Supercritical CO2’s high diffusion rates allow it to penetrate solids faster than a liquid solvent. The benefit of using Carbon Dioxide as an extraction solvent is its place in nature. Carbon Dioxide is a natural product which leaves behind no residues. CO2’s purity is its biggest advantage over all other solvents used for plant extraction. Currently, a popular extraction solvent is butane which can potentially leave heavy metals behind in your finished product.
Shatter is a refined version of BHO, which typically involves multiple steps to extract all the plant matter and solvents. These steps usually involve a pressure vacuum. Shatter is semi-transparent, usually with a yellow or amber color. It is usually a thin cake, which ‘shatters’ when you break a piece off, hence the name. Shatter is very potent and can be upwards of 90% THC.
