Separatory Funnel

A separatory funnel, also known as a separation funnel or separating funnel, is a laboratory apparatus used for separating immiscible liquids or liquids with different densities. It consists of a conical-shaped glass or plastic container with a stopcock at the bottom and a narrow neck at the top. The stopcock allows for controlled draining of the liquid layers.

Separatory funnels are commonly used in chemistry laboratories for various purposes, such as extracting compounds from a mixture, separating organic and aqueous layers, and performing liquid-liquid extractions. They are particularly useful when working with solvents that are immiscible, meaning they do not mix together.

To use a separatory funnel, the mixture of liquids is poured into the funnel, and after allowing the layers to separate, the stopcock is opened to drain the lower layer while keeping the upper layer in the funnel. The process can be repeated multiple times to further separate the components.

It is important to handle separatory funnels with care, as they can be fragile and the liquids being separated may be hazardous. Proper lab safety protocols should always be followed when using this equipment.
