As soon as the solution reaches the top end of the siphon tube. The condensed solvent comes in contact with the crude organic substance and dissolves it. The solvent vapors reach the cylinder through the inlet tube and conduce on passing upward into the condenser. The flask is heated in a water bath or sand bath. This entire assembly is fitted into the neck of a round bottom flask containing the solvent. A water condenser is attached to the cylinder at the top. This cylinder is provided with a siphon tube and an inlet tube. The crude substance is placed in a thimble-shaped filter paper which is then kept in a glass cylinder. The flask is repeated, extracting a portion of the material each time so that the solid material is constantly used as a pure solvent and the extracted material is concentrated in the flask. The solvent is added to the solvent reservoir flask and mounted onto a heating mantle. After heating, the condensed vapors of the solvent come in contact with the sample powder, and the soluble part of the powder gets mixed with the solvent for extraction. When the solvent surface exceeds the maximum height of the siphon, the solvent containing the extract is siphoned back. The Soxhlet extraction uses the solvent reflux and siphon principle to continuously extract the solid matter by pure solvent, which saves the solvent extraction efficiency and high efficiency. The sold sample is placed on a thimble-shaped filter paper, positioned into the Soxhlet extractor, and the device is assembled. The Soxhlet extraction method uses a small amount of solvent and is very cost-effective. This is a very useful technique for preparative goals in which the analyte is concentrated from the matrix as a whole or separated from specific interfering substances. In 1879, Franz Ritter von Soxhlet, professor of agricultural chemistry at the Technical University of Munich, developed this extraction technique. Soxhlet extraction is an advanced extraction technique that involves repeatedly circulating the same solvent through the extractor.
