PROBLEM TO BE SOLVED: To obtain a pipette capable of collecting a plurality of samples from microplates along one side thereof to apply them to gel grooves of one side even if there is difference in a gel groove interval or microcuvet interval or there is lack of uniformity in these interval standards. SOLUTION: Equal coil springs 3 are mutually interposed between a plurality of equal plates 1 and shaft rods are respectively allowed to pierce through the common holes of the respective plates and round blocks 4, 4' are fixed to both ends of the shaft rods and cylindrical cam cylinders 7, 7' each formed by obliquely cutting a part of one end of a cylinder and forming a cam surface by the cut surface 9 and the end surface of the cylinder are fitted on the round cast blocks 4, 4' against the elastic force of the coil springs and cam followers 8 are implanted in the peripheral surfaces of the round cast blocks 4, 4' so as to always come into contact with the cam surfaces. Pipette nozzles 5 are implanted in the rear surfaces of the respective plates and allowed to pierce the plates to be allowed to communicate with a pressure control system sucking and emitting a liquid sample from the nozzles 5 at the same time. |
