Abstract

The invention relates to a multi-channel pipetting device and system, belonging to the technical field of biological instruments. The multi-channel pipetting device comprises a transmission part and a pipetting part, wherein the transmission part comprises a plurality of racks, a plurality of gears and driving parts corresponding to the gears in number, each rack is correspondingly meshed with one gear, and one gear is fixedly arranged on each driving part; and the pipetting part at least comprises a plurality of pipette heads, and each pipette head is relatively fixed with one rack through a fixing assembly. According to a four-quadrant structure provided by the invention, an equipment volume can be reduced to the greatest extent, and the minimum spacing of relative distance between pipettes is ensured; according to the invention, the structure is simplified to the maximum extent, cost is reduced, and the structure is easy to disassemble and convenient to maintain; and a rare sliding block fixing and sliding rail moving arrangement mode is adopted in the invention, so the stability of a mechanism can be realized by a small number of structures, and the pipetting accuracy of the pipettes is ensured.

Description

technical field [0001] The invention relates to the technical field of biological instruments, in particular to a multi-channel pipetting device and system. Background technique [0002] In biological research experiments and actual production processes, it is often necessary to add one reagent to another reagent for a mixed reaction. Based on the particularity of biological reactions, the amount of reagent added needs to be quantified very accurately, and usually this operation step It needs to be repeated many times. In the early technology, it is usually completed by a common pipette with a relatively simple structure and function. This kind of pipette gun has the following general features; firstly, manual operation is required, and pipette tips with different volumes are used to achieve the quantification of the reagent to be pipetted. Second, due to the single setting of the gun head, different reagents need to be changed when moving different reagents, which is cumbe...
