The invention relates to a device for extracting one or more constituents, in particular THC and/or cannabinoids, from a mixture of substances, the device having a chamber, a plate accommodated in the chamber, at least one nozzle for feeding the mixture of substances into the chamber and a static charging unit, wherein the static charging unit is arranged to statically charge the mixture of substances, wherein the plate has a charge opposite to the static charge of the mixture of substances, so that the statically charged mixture of substances, or at least components thereof, adheres or is adherable to the plate. The invention also relates to a corresponding method.

A method for treating water in a spa or a hot tub includes, for example, suspending a water treatment dispenser from an upper end of a filter cartridge disposed in a skimmer of the spa or the hot tub. The dispenser includes a water treatment material. A supply of water is passed from the spa or the hot tub into the skimmer and through the filter cartridge so that the dispenser suspended in the filtered water in the filter cartridge is operable to dispense the water treatment material from the dispenser, and a supply of treated filtered water from the filter cartridge is returned to the spa or the hot tub. A cover, for example, may be employed when the dispenser is not used.

A system is provided that includes a solvent source; a canister adapted to contain plant material and positioned downstream of the solvent source; an extract container positioned for receiving and collecting at least a portion of an extract solution from at least the canister, the extract container further positioned to separate at least a portion of the solvent from at least the portion of the extract solution, thereby providing a recycled solvent; a solvent collection line for directing the recycled solvent; and a coolant line positioned for directing coolant that is thermally coupled to at least a portion of the solvent collection line for cooling the recycled solvent that is flowing through the solvent collection line.

A micelle mixture including a solute and a liquid, the solute including at least one of a terpene compound, a terpenoid compound, a phenolic compound, a terpenophenolic compound, and a terpenoresorcinolic compound. A multimer aggregate comprising a solute and a liquid, the solute comprising at least one of a terpene compound, a terpenoid compound, a phenolic compound, a terpenophenolic compound, a terpenoresorcinolic compound, a THCa compound, a CBDa compound, a CBNa CBCa compound, a THC compound, a CBN compound, a CBD compound, a CBC compound, a CBGa compound, a CBG compound, a THCVa compound, and a THCV compound.
