The extraction of compounds from solid materials, if carried out by long-term leaching, is carried out in low yields and with a long time, so that the soxhlet extractor is one of the laboratory equipment commonly used for extraction operations.
DescriptionĪ problem often encountered in laboratory research and chemical production activities is the separation and purification of substances. Meanwhile, the function of negative pressure suction is added, so that the extraction liquid can completely flow back, the loss of the solvent and the extraction substance is reduced, the device is quickly started and stopped, and the operation efficiency and the yield are improved. The utility model discloses carry out the design improvement to the soxhlet extractor, design negative pressure suction device on extracting the bottle, set up the piston simultaneously on steam connecting pipe, the normal extraction operation of being convenient for and the switching of negative pressure suction operation. The utility model discloses a soxhlet extractor of extract is retrieved in vacuum, including top-down consecutive condenser, extractor, draw the bottle, be equipped with siphon and steam connecting pipe on the extractor, set up control piston 1 on the steam connecting pipe, draw bottle one side and be provided with the temperature sensor interface, the opposite side passes through negative pressure interface and vacuum pump system connection, and negative pressure interface front end is provided with control piston 2.
