Instrument for extracting active substance of organisms

The utility model provides an instrument for extracting an active substance of organisms. The instrument comprises a rack, a workbench, a liquid transfer assembly and a separation assembly, wherein the liquid transfer assembly comprises a first mounting plate, a first driving unit, pipettes, piston rods and a first driving component; the first driving unit is used for driving the first mounting plate to move along the height direction of the rack; the pipettes are connected on the first mounting plate; the piston rods are inserted in the pipettes and are hermetically fit with the inner walls of the pipettes; the first driving component is used for driving the piston rods to move up and down relatively to the pipettes; the separation assembly comprises a second mounting plate, a second driving unit, casings, magnetic bars and a second driving component; the second driving unit is used for driving the second mounting plate to move along the height direction of the rack; the casings are fixed on the second mounting plate; the second driving component is used for driving the magnetic bars to move up and down relatively to the casings; the upper ends of the casings are provided with openings and the lower ends are blind ends; the magnetic bars are inserted in the casings from the openings at the upper ends of the casings by way of clearance fit. The instrument improves the extraction efficiency of the active substance of organisms and the extracted sample has higher purity.
