Problems solved by technology

[0003] At present, due to the presence of gas in the cell mixture when the pipette is pumping the cell mixture, the pipette barrel uses the pressure difference to make the cell mixture enter the inside of the pipette barrel when pumping the cell mixture into the culture medium. During the process, the pressure in the culture solution becomes smaller, and part of the gas in the culture solution is precipitated due to the problem of pressure drop, resulting in the inability to draw a full range of cell mixture in the pipette

Abstract

The invention provides a cell pipette and relates to the technical field of biology. According to the scheme, the cell pipette comprises a pipette barrel, a suction tube body and a compression structure, a compression structure for compressing air in the pipette barrel is mounted at the top end of the pipette barrel; the bottom of the pipette barrel is connected with a suction pipe body communicated with the interior of the pipette barrel; an exhaust assembly for exhausting air in the pipette barrel is mounted at the top of the pipette barrel; and the suction pipe body is provided with a blocking assembly for isolating the inside of the pipette barrel from the outside air. According to the invention, full-scale cell mixed liquid can be pumped.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a cell pipette gun. Background technique [0002] Cell culture is also called cell cloning technology, and the formal term in biology is cell culture technology. No matter for the entire bioengineering technology or one of the biological cloning technologies, cell culture is an essential process, and cell culture itself is a large-scale cloning of cells. Cell culture technology can transform a single cell into simple single cell or rarely differentiated multi-cell through mass culture, which is an essential part of cloning technology, and cell culture itself is cell cloning. [0003] At present, due to the presence of gas in the cell mixture when the pipette is pumping the cell mixture, the pipette barrel uses the pressure difference to make the cell mixture enter the inside of the pipette barrel when pumping the cell mixture into the culture medium. During the process, the pressur...
