Technical Field

[0001] The utility model relates to the field of flow cytometers, in particular to a flow cytometer. Background Art

[0002] Flow cytometry is a highly advanced biotechnology instrument used to quickly and efficiently analyze and count individual cells within a cell population;

[0003] Application number: CN202022957497.X, discloses a micro flow cytometer, when the flow cytometer body is accidentally touched, the slide seat slides on the slide rod, driving the angle of the hinged rod to change the shock absorption of the flow cytometer body, and preventing the flow cytometer body from being damaged, the slide seat slides on the slide rod, the slide seat drives the push rod to move, the push rod drives the push block, the push block drives the auxiliary slide seat to slide on the auxiliary slide rod through the linkage rod, the auxiliary slide seat drives the moving rod to move upward, the moving rod drives the protective plate to move upward, and the flow cytometer body is protected to prevent the next accidental touch in a short time, which can effectively protect the flow cytometer body;

[0004] However, flow cytometers often generate a lot of waste liquid when in use, such as fluorescent waste liquid, and some of the waste liquid may contain harmful substances. Compared with the flow cytometer in the patent, it is difficult to collect these waste liquids. When discharging the waste liquid, the operator may accidentally touch the waste liquid, which may cause harm to the human body. For this reason, we propose a flow cytometer. Summary of the invention

The water level sensor detects the water level inside the collection tube and displays it through a PLC controller. When the defined water level is reached, the PLC controller controls the electric push rod, the electric output rod, the connecting piece, and the inner tube to move downward along the guide rod, so that the waste liquid discharge pipe is separated from the inner tube, and the inner tube is retracted to the inside of the outer tube, reserving more space for taking out the collection tube, so that the collection tube can be taken out directly without accidentally touching the waste liquid and causing harm to the human body. The sealing rubber cover can ensure the tightness of the connection between the inner tube and the outer tube.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:
