An automatic pipetting device

Abstract

The invention provides an automatic pipetting device. The automatic pipetting device comprises a round rotatable circular disc, a plunger pump assembly and a channel for communicating the circular disc, the plunger pump assembly and an outer container. The plunger pump assembly is used for releasing liquid and sucking the liquid through the pushing and pulling of external power; and the liquid flows in the channel and the rotatable circular disc is used for controlling the liquid to flow into and flow out of a specific channel. A pipetting needle is connected with the outlet of the channel in a transparent plate; the pipetting needle is inserted into the liquid in the container; and the container sleeves the bottom of the transparent plate and is in seamless connection with the transparent plate. The circular disc rotates to the channel for pipetting and is communicated with the channel in the transparent plate. The automatic pipetting device provided by the invention has a good sealing performance, can completely realize automatic operation, and is simple and convenient to operate; and the working efficiency is greatly improved and the workload of testers of a laboratory is alleviated. The automatic pipetting device is used in a disposable manner so that cross contamination between samples can be effectively prevented and the accuracy of an experiment result is improved.

Description

technical field [0001] The invention relates to a cover suitable for automatic pipetting, which belongs to the technical field of biomedicine. Background technique [0002] In biochemical experiments in the fields of disease detection, food safety, forensic identification, and genomics, the pretreatment process of biological samples is the most cumbersome, and pipetting operations are repeatedly interspersed in various processes, such as sample transfer, reagent addition, and liquid mixing. Evenly, the processed samples can be put into the corresponding testing equipment for analysis, research and testing. At present, automatic liquid pipetting uses automatic liquid pipetting workstations, which are not suitable for individual detection experiments in laboratories. At present, in biochemical laboratories, pipetting guns are mainly used to manually perform sample pretreatment operations. When the sample processing volume is slightly large, manual sample processing is time-co...

At present, the automatic pipetting uses an automated pipetting workstation, which is not suitable for individual detection experiments in laboratories

At present, in biochemical laboratories, pipetting guns are mainly used to manually perform sample pretreatment operations. When the sample processing volume is slightly large, manual sample processing is time-consuming and laborious, and pipetting errors are prone to occur, and samples are easily contaminated.
