Description

Soxhlet extractor

Technical Field

The utility model relates to a soxhlet extractor technical field especially relates to a soxhlet extractor.

Background

The Soxhlet extractor consists of an extraction bottle, an extraction tube and a condenser, wherein the two sides of the extraction tube are respectively provided with a siphon and a connecting tube, and the joint of each part needs to be tight and cannot leak gas. During extraction, a sample to be detected is wrapped in a filter paper bag and is placed in an extraction tube. Adding the extractive solution into the extraction bottle, heating the extraction bottle, gasifying the extractive solution, introducing into a condenser via a connecting pipe, condensing into liquid, and leaching certain substance in the sample. When the liquid level of the extracting solution in the extracting tube reaches a certain height, the extracting solution dissolved with certain substances flows into the extracting bottle through the siphon. The extracting solution flowing into the extracting bottle is continuously heated, gasified, ascended and condensed, and is dripped into the extracting tube, and the process is repeated in a circulating way until the extraction is complete.

During the separation and extraction experiment, the Soxhlet extractor needs to be matched with filter paper for use. During the test, the medicine is wrapped by filter paper and put at the bottom of the extraction tube, and the medicine is soaked and extracted by solvent. After the extraction experiment is finished, the filter paper bag needs to be taken out, dried and weighed to calculate the extraction amount. Due to the influence of the infiltration of the solvent, the filter paper becomes soft and deformed, and the filter paper extracted by using tweezers is easily damaged, so that the medicine is scattered, and the experimental result is influenced.
