Using a still for making cannabis oil
A still is an apparatus used to distill liquid mixtures by heating to selectively boil and then cooling to condense the vapour. Distillation is the process of separating the components or substances from a liquid mixture by using selective boiling and condensation. Distillation may result in essentially complete separation (nearly pure components), or it may be a partial separation. Partial separation increases the concentration of selected components in the mixture. In either case, the process exploits differences in the relative volatility of the mixture’s components. Distillation is a unit operation of practically universal importance in industrial chemistry. Ethanol boils at a much lower temperature than water. Therefore, simple distillation can separate ethanol from other compounds by applying heat to the mixture.
Ethanol extraction is prized for its ability to create a safe and pure cannabis product without the risk of contaminants and can be used to make a full spectrum extract. In a controlled setting, ethanol can be a powerful and affordable solvent that creates highly potent extracts. These extracts can go into your cartridges, edibles, tinctures, topicals, and anything else you can think of.
Ethanol is the most expensive part of marijuana oil production. A still allows you to reclaim up to 90% of your ethanol when making cannabis oil. Reusing ethanol negates the cost benefit of using dangerous solvents like isopropyl alcohol to make cannabis oil. Distilled water, brandy and other essential oils can also be made with a still.
