Ethanol Still (Solvent Recycling System)
This Ethanol 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 the still.

Remove the top cover.
Pour the alcohol solution into the tank.
Place the top cover onto machine body, while ensuring sure that the silicone seal is tightly secured around the entire rim. This must be airtight.
Ensure that the machine is on a stable surface.
Connect the power cord from the top cover to the machine body.
Place the storage bottle as shown in the diagram.
Connect the power cord to the power outlet (mains).
Turn on the switch and turn the dial to 80 – 90 °C. The alcohol in the tank is heated and evaporation takes place. The alcohol will flow through the outlet into the storage bottle.
The machine will cycle between on and off, indicated by the red and green lights. This ensures that the temperature is kept in the desired range and is part of normal operation.
Switch off the machine when there is no alcohol left in the tank.
Do not set the temperature above 100 °C for more than 10 minutes at a time. This will damage the machine.
Use the unit in a dry and well-ventilated area.
Do not remove the cover while the unit is in operation, wait until the unit has cooled down before removing the top.
Making RSO/FECO and similar: Use an oven-safe dish to hold the herbal extraction (tincture) and add water to the bottom of the tank when recovering alcohol from tinctures. This makes it easier to recover the oil and to clean the machine.
