Winterization
What it is & why it is essential to cannabis extraction?
The process of winterization involves lowering the temperature of a solution in order to precipitate out the fats and waxes. This is done in order to increase the purity of the final products, as well as reduce the chance for rancidity and foul-tasting oils.

Introducing the new Ai separatory funnel kits with all PTFE valves. A separatory funnel, also known as separation funnel, separating funnel, or colloquially sep funnel, is a piece of laboratory glassware used in liquid-liquid extractions to separate (partition) the components of a mixture into two immiscible solvent phases of different densities. Typically, one of the phases will be aqueous, and the other a lipophilic organic solvent such as ether, MTBE, dichloromethane, chloroform, or ethyl acetate. All of these solvents form a clear delineation between the two liquids. The more dense liquid, typically the aqueous phase unless the organic phase is halogenated, sinks and can be drained out through a valve away from the less dense liquid, which remains in the separatory funnel.
