Extraction Tube B

An extraction tube is a piece of laboratory equipment used for the extraction of compounds from a mixture. It is typically a long, narrow tube made of glass or plastic, with a stopcock or valve at the bottom and a funnel or opening at the top. The mixture to be extracted is placed in the tube, and a solvent is added. The solvent dissolves the desired compound, which can then be separated from the mixture by draining the solvent out of the bottom of the tube. Extraction tubes are commonly used in organic chemistry and biochemistry for the isolation and purification of compounds.
