Micropipettor based on automatic suction and transfer technology

Abstract

The invention discloses a micropipettor based on automatic suction and transfer technology. The micropipettor comprises a bottom plate, stand columns, a crossbeam and a liquid collection cylinder, wherein the left side and right side of the top end surface of the bottom plate are symmetrically provided with the stand column, the top ends of the two stand columns are respectively provided with thecrossbeam, the bottom end of the crossbeam is provided with a slide groove, an inner cavity of the slide groove is provided with a lead screw, one end of the lead screw is rotatably connected onto theinner cavity wall of the slide groove by virtue of a bearing seat, the other end of the lead screw penetrates through the side end of the slide groove and is fixedly connected onto a motor shaft of amotor, the motor is fixedly connected onto the crossbeam, the lead screw is rotatably connected onto the crossbeam by virtue of a bearing, the lead screw is sleeved with a movable seat matched with the slide groove, and the bottom end of the movable seat is provided with the liquid collection cylinder. The transfer work of the liquid collection cylinder is completed by utilizing the motor, the lifting of the liquid collection cylinder is completed by utilizing a first telescopic apparatus, the liquid collection and release work can be completed by utilizing a second electric telescopic apparatus, the liquid collection process and liquid release process as well as the liquid transfer process are automatically completed, the influence from the manual factor is slight, and the liquid collection precision is high.

Description

technical field [0001] The invention relates to the technical field of pipettes, in particular to a micropipette based on automatic suction and transfer technology. Background technique [0002] A pipette, also known as a pipette gun, is an instrument for quantitatively transferring liquids and is widely used in biology, chemistry and other fields. Micropipette is an essential tool for biochemical experiments or molecular biology experiments. [0003] A micropipette is a precision liquid-taking device (commonly known as a gun) that can be adjusted at will within a certain capacity range. The basic principle is to rely on the up and down movement of the piston in the device, and the moving distance of the gas piston is realized by the adjustment wheel to control the screw structure. , push the button to drive the push rod to move the piston down to remove the gas in the piston chamber. After letting go, the piston returns to its original position under the action of the ret...

AI Technical Summary

Problems solved by technology

[0004] Traditional pipettes are mostly operated manually. Although there are scale marks on the pipette, due to irresistible factors such as line of sight deviation in human operation, the accuracy of the volume is limited, and it is difficult to meet the needs of the current stage.
