Abstract

The invention discloses an automatic pipetting workstation which belongs to an automatic pipetting device for biological and chemical experiments. The system comprises such main components as a working platform, a support frame, an X-axis precision electric-controlled flat pipetting table, an X-axis drive motor, an X-axis auxiliary guide, a Y-axis overarm brace, a Y-axis guide column, a Y-axis screw rod, a manipulator module, an electric cabinet, a computer, etc. The working platform is provided with a pipette tip recovery zone and can be provided with a pipette tip storage module, a sample storage module and the like as required. The automatic pipetting workstation has the advantages of less cross contamination, high precision, simple and convenient operation, good flexibility, high efficiency, strong applicability, low use cost, etc.

Description

technical field [0001] The invention relates to an automatic pipetting device for biological and chemical experiments, more precisely, an automatic liquid processing system for accurately distributing and transporting liquid reagents and liquid samples at the same time. Background technique [0002] With the rapid development of science and technology, the research work of biological and chemical laboratories is no longer a small-scale experiment centering on a few devices and operating a number of samples, but facing more complex research objects and increasing number of samples, using A variety of experimental techniques for multi-channel, diverse large-scale experiments. Such as library screening in genetics, genome sequencing and gene chip research, search and identification of differential proteins in proteomics, screening of protein crystallization, analysis of advanced structures, and large-scale compound screening and identification in new drug discovery. The amount...

Problems solved by technology

There are many problems in manual operation: a large amount of sample processing not only requires a lot of manpower, material resources and time, but also brings a lot of human errors due to manual operation, which makes the pipetting accuracy of sample processing low, the probability of error is high, and the stability of sample processing and poor repeatability

Moreover, the distances between the multiple nozzles of these liquid handling systems are all fixed, corresponding to the well spacing of multi-well plates, so they are not suitable for situations with large spacing, such as test tubes, reagent bottles, glasses, etc.

However, in practice, many samples are collected and stored in test tubes or plastic sample tubes. In this way, the samples need to be transferred to a multi-well plate for sample processing. The operation is cumbersome and error-prone.

[0005] Moreover, the existing liquid handling systems are basically monopolized by imported equipment. These imported equipment have high speed, high precision and good working stability, but these equipment are expensive, and the cost of accessories and consumables is also very high. promotion, domestic liquid pipetting equipment has a low market share due to its simple structure, single function, low accuracy and stability
