In this way, the solvent circulates in the instrument and concentrates the substances to be extracted into the flask below. It will carry the extracted material and flow into the flask from the side siphon if the solvent reaches a certain height in the extractor. After boiling, the solvent vapor enters the condenser tube from the flask, and the condensed solvent flows back into the filter paper cylinder to extract the sample. Connect the flask, extractor, and reflux condenser, and connect the condensed water, and heat. Or, add the extraction solvent and zeolite to the extraction flask (if there are no zeolite, glass beads or broken porcelain pieces can be used, the purpose is to prevent bumping).ģ. If the sample is light, use absorbent cotton to press the sample. The extracted material should not leak out of the filter paper tube, so as not to block the siphon tube. (A loop of cotton thread can be placed on the filter paper cartridge to facilitate the removal of the filter paper cartridge after extraction.) The height of the extract cannot exceed the siphon tube, otherwise, the extract cannot be fully soaked by the solvent, which will affect the extraction effect. Note that the filter paper cartridge should not only be close to the wall of the device but also be easy to pick and place. Make the filter paper disc into a filter paper tube corresponding to the size of the extractor, and then put the sample to be extracted into the filter paper tube and load it into the extractor. Note that it must be fastened with a clamp or cable tie to prevent the water pipe from falling off.ġ. Move the host to the workbench, connect the water inlet pipe on the back of the instrument to the faucet, and lead the water outlet pipe to the sewer. Open the package and check whether the instrument and accessories are complete and damaged. The petroleum ether flowing into the extraction bottle continues to be heated to vaporize, rise, condense, and drip into the extraction tube, and so on, until the extraction is complete.

The petroleum ether dissolved in the crude fat flows into the extraction bottle through the siphon, when the liquid level of petroleum ether in the extraction tube reaches a certain height. After the petroleum ether is vaporized, it will rise from the connecting pipe into the condenser, and the condensed liquid drops into the extraction pipe to extract the lipids in the sample. Add petroleum ether to the extraction bottle, and then heat the bottle. The tested sample is packed in a degreased filter paper bag and placed in the extraction tube when they are to be extracted. All joint parts should be tight without leaking. A siphon pipe and a connecting pipe are arranged on both sides of the extraction tube. The Soxhlet extractor consists of three main parts, condenser, extraction bottle, and extraction tube. This equipment has a reasonable design, stable function, high accuracy, labor-saving operation, and time-saving. The soxhlet extractor is a device for laboratory extraction thimbles developed based on the classic Soxhlet extraction technology.
