Abstract: A balance mechanism comprises a working device, a connecting arm assembly having a variable length, a torque-balancing assembly, a weighting member, and a connecting member. The connecting arm assembly couples to the working device. The connecting arm assembly is pivoted to the torque-balancing assembly by a pivot. The weighting member couples to the torque-balancing assembly. The connecting member connects the connecting arm assembly and the torque-balancing assembly. As the distance between the working device and the pivot changes, the distance between the weighting member and the pivot changes accordingly, so that a dynamic balance can be achieved.

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.
