Quick answer: A Separating Funnel is a pear-shaped vessel with a stopcock, used for liquid-liquid extraction — separating two immiscible liquids of different densities, such as during organic synthesis workup. Funnel, Separating is priced at approximately ₹600 (indicative market benchmark, incl. GST, August 2026).
A separating funnel is a pear-shaped glass vessel fitted with a stopper at the top and a stopcock at the bottom, used to separate two immiscible liquid layers of differing density. After shaking to mix the liquids and allowing them to settle into distinct layers, the stopcock is opened to drain the lower layer while the upper layer remains in the funnel, allowing a clean phase-boundary visualization and controlled dispensing. It’s a standard technique in liquid-liquid extraction, used for isolating a desired compound from a reaction mixture in college and research organic chemistry laboratories.
