Summary:A three-way switch is arranged at the connection position of siphon, overflow tube and liquid-return tube, so any two of them can be connected with each other as required. Additionally, a triangular funnel and a porous glass plate are reversely connected to two ends of a single glass tube and a single valve is set in the glass tube, allowing liquid to flow only from triangular funnel to a special funnel at the end where porous glass plate is set for continuously automatic extraction of liquid-solid or liquid-liquid for the solid or liquid with different specific weights. This device is suitable for extraction even if distribution coefficient K is less than 1.5. A hollow glass body is arranged at the neck of condensing tube to decrease the volatilization and prevent external water vapour from going into the extractor.
