Abstract:
Apparatus is described to effect extraction of bulky solids with hot solvents. The extraction chamber is heated by boiling solvent vapors and filled by condensation of those vapors. When filled with solvent, the extraction chamber is emptied automatically by a siphon, as in a conventional Soxholet extractor. A novel con denser provides a large and flexible connection to the extraction chamber and avoids the use of glass joints and the attendant hazard of breakage. The entire apparatus is useful for repeated automatic extraction of various solid materials with fresh batches of hot solvents as, for example, in the hot extraction of glass fiber or cellulose paper to be used in chromatography.
