Abstract: An efficient automatic liquid-liquid extracting machine includes a body. At least one set of stirring extractor is arranged on the body, the stirring extractor includes a cylindrical separating funnel and a stirring motor that are fixed on the body, a bottom funnel opening of the cylindrical separating funnel is connected to a three-way liquid separating device, the stirring motor is arranged opposite to the opening of the cylindrical separating funnel, a motor shaft of the stirring motor is connected to a stirring device, and a stirring end of the stirring device penetrates into the cylindrical separating funnel. Since multiple mechanical stirring devices are used in the analysis of semi-volatile organics, the extraction process for multiple samples can be performed synchronously at the same time, and the solvent and the solute are brought into full contact due to the rotary mechanical stirring up and down.
