Our Residual Solvent Test (RST) identifies the presence of harmful solvents, impurities, and/or other added odorants and chemicals.

These types of concentrates are produced by using a solvent (such as butane, CO2, ethanol, propane, etc.) to extract cannabinoids and terpenoids from plant material.

Finally, heat, vacuum, and/or other methods are applied to purge out any remaining solvent from the concentrate.
