A piece of laboratory glassware with a stopcock used to separate two immiscible liquids of different densities or to perform liquid-liquid extraction. The denser liquid settles to the bottom and can be drained off separately. Essential for solvent extraction techniques.
Separating funnels are used in laboratory solvent extraction to purify organic compounds from aqueous reaction mixtures. They are used to remove impurities or transfer a desired compound between solvents. Industrial-scale equivalents are used in pharmaceutical and chemical manufacturing.
Many organic solvents used in separating funnel extractions are flammable and toxic. The funnel should be vented regularly during use to release solvent vapour pressure. Work should be conducted in a fume hood.
