[0002] Soxhlet extractor, also known as fat extractor, is a device for extracting compounds from solid substances. Soxhlet extractor consists of three parts: extraction bottle, extraction tube, and condenser. During extraction, the solvent in the extraction bottle is heated to vaporize, rises from the connecting tube into the condenser, condenses into liquid and drips into the extraction tube to extract the compounds in the sample. When the solvent level in the extraction tube reaches a certain height, the solvent containing the extracted compounds flows into the extraction bottle through the siphon. The solvent flowing into the extraction bottle continues to be heated, vaporized, rises, condensed, and drips into the extraction tube, and the cycle repeats until the extraction is complete.
