Pipetting device and biochemical analysis instrument

Abstract

The utility model discloses a pipette device and biochemical analysis instrument, pipette device includes a plurality of memory, a plurality of pipette assembly, drive mechanism and pump, and the memory is configured to store liquid and / or solid matter, and the pipette assembly is configured to transfer liquid, and the drive mechanism is connected with the pipette assembly, and the drive mechanism is configured to drive the movement of pipette assembly to adjust the position of pipette assembly relative to the memory, and the pump is communicated two pipette assemblies among a plurality of pipette assemblies and provides power for the two pipette assemblies to transfer liquid from one memory to another memory. In this way, the pipette device adjusts the position of the pipette assembly relative to the memory using the drive mechanism, so that the pipette assembly absorbs liquid at different positions in the memory or releases liquid to different positions in the memory under the action of the pump, transfers liquid between the two memories, and achieves the effect of dissolving solid matter or mixing different liquids.
