Abstract
The invention provides a pipetting needle distance adjustment apparatus, and relates to the technical field of reagent conveying. The pipetting needle distance adjustment apparatus comprises adjustment blocks, pipetting needles, a drive device, at least a fixing block unit and a horizontally-arranged first horizontal fixing device, wherein each fixing block unit comprises a plurality of pipetting needle fixing blocks arranged in a side-by-side manner, the adjustment blocks are respectively arranged between the adjacent two pipetting needle fixing blocks, the drive device drives the adjustment block to move up and down, the adjustment block contacts and squeezes the pipetting needle fixing blocks positioned on both sides of the adjustment block when the adjustment block moves downward so as to increase the distance between the adjacent pipetting needle fixing blocks, the pipetting needle fixing blocks are movably fixed on the first horizontal fixing device, and the pipetting needles are fixed on the pipetting needle fixing blocks. According to the present invention, the whole structure of the pipetting needle distance adjustment apparatus is simple, and the production process and the assembly process are convenient.
Description
technical field [0001] The invention relates to the technical field of reagent transmission, in particular to a device for adjusting the distance between pipetting needles. Background technique [0002] Sampling and pipetting instruments are widely used in biochemical, molecular, cell and other biological experiments. Its main function is to collect and transfer a certain volume of liquid. Among the widely used sampling and pipetting instruments, they are divided according to the channel type: There are multi-channel and single-channel; divided according to the power form of sampling and pipetting: manual and electronic. Among them, multi-channel pipetting instruments are widely used, which can realize one-time accurate multi-channel liquid sampling and pipetting. [0003] There is a multi-channel pipetting device in the prior art, which includes several pipetting devices and a frame for fixing the pipetting device. The pipetting device includes a needle, a syringe and a pu...
