Abstract

A multi-channel loading device comprises a beam, a plurality of sampler injector fixing rods are arranged on the beam, a sample placing pad is arranged below the beam, each sampler fixing rod is provided with a sampler comprising a sampling pin which is hollow and arranged vertically, the lower part of each sampling pin is intercalated with a suction end, each sampling pin is arranged on an injection pump base and connected with an injection pipeline in the injection pump base, each injection pipeline is respectively provided with a pressure sensor used for measuring the pressure in each injection pipeline, the upper part of each injection pump is provided with a push-and-pull rod inserted into a solution cavity vertically, the top of each push-and-pull rod is connected with a leadscrew nut which is rotationally mounted on a leadscrew vertically. The invention aims at providing the multi-channel sampling device with high accuracy and good stability of solution suction and separation, strong adaptability and capacity in reducing and avoiding cross infection among samples.

Description

technical field [0001] The invention relates to a device for diluting, distributing and mixing reagents. Background technique [0002] Multi-channel sampling equipment is used for fully automated sample and reagent dilution, distribution, mixing, and automatic management of related data documents. Multiple sampling channels refer to having multiple samplers. The multi-channel sampling equipment can be used for all automatic liquid sampling in the process of medical inspection, food inspection, biological experiment and so on. For example, high-throughput screening of drugs, biological laboratories, pre-processing of gene sequencing, pre-PCR, post-PCR processing, solid phase extraction, liquid-liquid extraction, DNA / RNA separation, automatic protein precipitation operations, etc. Specifically, it mainly includes: nucleic acid purification, PCR setting and purification, gene and protein sequencing processing, sample standardization, biochip sample preparation, rapid clone scr...
