Description

Array type micropipettor

Technical Field

The utility model belongs to the technical field of the micropipette, especially, relate to an array micropipettor.

Background

The micropipette is a precision instrument for measuring trace liquid, and particularly in the field of life science research, a certain liquid is required to be quantitatively sucked, and the technology has various mature solutions depending on application scenes, such as a common micropipette gun, an electric pipette, an ear washing ball, a pipette with scales, a quantitative electronic pump and the like.

However, in the scientific research process, it is often encountered that liquids with different densities are simultaneously in the same container and are arranged in layers, such as oil-water layering in the chemical field, and such as layering in the PBMC separation process by density gradient centrifugation in the biomedical field, and the liquids of each component need to be separated.

In some areas of subdivision, there is considerable room for improvement in the process of extracting the middle layer PBMC (buffy coat) when separating PBMC using lymphocyte separation fluids. The current commonly used method for sucking the leucocyte is a micro pipette (1 ml) +1ml disposable pipette tip, a 2-5ml pasteur pipette or an electric pipette and a sterile pipette. The methods have defects, for example, the liquid suction efficiency is low by adopting the 1ml gun head, the hand can repeatedly pass through the upper part of the tube orifice, and the pollution is easily caused. The disadvantage of using the pasteur pipette to absorb liquid is that the position of the tube tip is large, the white film layer is easy to be disturbed, the desired position cannot be accurately absorbed, meanwhile, the tube head needs to be squeezed back and forth by hands, the hand cramp is easy to cause, and meanwhile, the method also has the risk of passing through the tube orifice for many times.
