[0004] However, in use, there are the following defects:

[0005] Since the device can only rotate cells uniformly at one speed, it is impossible to observe the separation of the same cells at different speeds, thus affecting the practicality of the device. Utility Model Content

[0006] The purpose of the present application is to provide a high-speed centrifuge device for biological cells, which solves the problem raised in the background art that the device can only rotate cells uniformly at one speed, and the separation of the same cells at different speeds cannot be observed, thus affecting the practicability of the device.

[0007] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a high-speed centrifuge device for biological cells, comprising a base, an outer plate, a rotating seat, a fixed switch and a slider, wherein the outer plate is fixedly installed on the outer side of the top of the base, a motor is fixedly installed on the bottom inside the base, a rotating shaft is fixedly installed on the top of the motor, a rotating rod is fixedly installed on the center of the top of the rotating shaft, a rotating seat is fixedly installed on the side wall of the rotating rod, a fixed test tube slot is provided on the top of the rotating seat around the rotating rod, a slot is provided on the top of the rotating rod, a slide slot is fixedly connected to the bottom of the side wall of the rotating seat, a telescopic rod is fixedly installed on the side wall of the rotating seat, the other end of the telescopic rod is fixedly connected to the mobile test tube slot, a slider is fixedly connected to the bottom of the mobile test tube slot, the slider is horizontally slidably connected to the slide slot, and the slide slot is fixedly connected to the rotating seat.

At the same rotation speed, the farther the distance, the greater the angular velocity. The length of the telescopic rod is adjusted according to the needs of the actual test, and the slider slides horizontally in the slide groove and is fixed by the fixed switch, so that the mobile test tube slot can freely change the distance to the center of the rotating rod, thereby obtaining different angular velocities. The effect of the centrifugation is also different due to the change in angular velocity. Different centrifugal effects can be obtained by comparing with the test tubes in the fixed test tube slot. There is no need to conduct multiple tests for observation, which improves the efficiency of the centrifugation and enhances the practicality of the device.
