A separatory funnel is commonly used to perform an acid-base extraction. [3] Acid-base extraction utilizes the difference in solubility of a compound in its acid or base form to induce separation. [4] Typically, the desired compound is changed into its charged acid or base form, causing it to become soluble in aqueous solution and thus be ...
The tap-controlled outlet is designed to drain the liquid out of the funnel. On top of the funnel there is a standard taper joint which fits with a ground glass or Teflon stopper. [4] To use a separating funnel, the two phases and the mixture to be separated in solution are added through the top with the stopcock at the bottom closed.
Laboratory-scale liquid-liquid extraction. Photograph of a separatory funnel in a laboratory scale extraction of 2 immiscible liquids: liquids are a diethyl ether upper phase, and a lower aqueous phase. Soxhlet extractor. Extraction in chemistry is a separation process consisting of the separation of a substance from a matrix. The distribution ...
Electrophoresis, separates organic molecules based on their different interaction with a gel under an electric potential (i.e., different travel) Capillary electrophoresis; Electrostatic separation, works on the principle of corona discharge, where two plates are placed close together and high voltage is applied. This high voltage is used to ...
A separatory funnel used for liquid–liquid extraction, as evident by the two immiscible liquids.. Liquid–liquid extraction, also known as solvent extraction and partitioning, is a method to separate compounds or metal complexes, based on their relative solubilities in two different immiscible liquids, usually water (polar) and an organic solvent (non-polar).
It is primarily used together with a Büchner funnel fitted through a drilled rubber bung or an elastomer adapter (a Büchner ring) at the neck on top of the flask for the filtration of samples. The Büchner funnel holds the sample isolated from the suction by a layer of filter paper. During filtration, the filtrate enters and is held by the ...

A funnel for hot filtration Two funnels, A - a simple stemmed funnel. B - a ground glass powder funnel. Plain funnels exist in various dimensions, with longer or shorter necks. Filter funnels have a neck of a thin capillary tube and ribs which increase the filter-papers' effectiveness and thus accelerate the process of filtering. [1]
