Abstract:
A multi-channel pipetting assembly includes a linkage member and a plurality of pipetting structures arranged in parallel. Each pipetting structure includes a pipette body, a piston rod, a piston tube, and an elastic element. The pipette body has a plurality of air chambers with different inner diameters, and the air chambers are arranged axially and communicate with each other. The piston rod is fixed to the linkage member. The piston tube is sleeved on the piston rod. The piston rod and the piston tube are located in the pipette body, and are axially and reciprocatingly movable in the pipette body. The piston rod matches the air chamber with the smallest inner diameter, and the piston tube matches the remaining air chambers. The elastic element is telescopically sleeved on the piston rod and corresponds to the piston tube. Therefore, a plurality of volume ranges meeting the accuracy requirements can be provided.
