Abstract
Provided herein are systems and methods for the facile extraction and purification of oils from plant material, including cannabis and hemp. The systems and methods herein are versatile, and may utilize a wide range of solvents to extract oils from a variety of plant-based material. Further, the provided systems and methods are closed loop, reducing the loss solvent and decreasing the risk of safety concerns such as human exposure to solvent chemicals or explosion of volatiles. In some embodiments, the systems and methods remove impurities from the extracted oils, for example waxes or other precipitates, and provide a higher purity and higher quality extract.
