Technical Field

[0001] The utility model relates to the technical field of cell centrifugal separation, in particular to a cell centrifugal separation device for gene detection. Background Technique

[0002] A centrifugal separation device is a machine that uses centrifugal force to separate the components in a mixture of liquid and solid particles or liquid and liquid. In cell separation, a centrifuge is needed to perform centrifugal separation on cells to facilitate the extraction and detection of substances inside the cells.

This utility model can effectively fix test tubes, improve the centrifugal separation effect, have a high working quality, generate less vibration during operation, prevent the base from colliding violently with the desktop, and have less working noise.

[0004] However, the above separation device has the following defects: The device fixes the test tube by directly inserting the test tube into the test tube slot. This method may cause the test tube to be unstable when the centrifuge rotates at high speed, increasing the risk of accidental detachment, which may damage the test tube or pose a danger to the operator. In addition, the design of the test tube slot limits its flexibility and can only hold test tubes of specific specifications, which restricts the applicability of the device when dealing with test tubes of different sizes. If there are various specifications of test tubes in the laboratory that need to use this equipment, this fixing method is not flexible enough and may require additional adapters or adjustment tools to adapt to test tubes of different sizes.

[0018] Optionally, in a possible implementation manner, a rotating roller is rotatably provided on the rotating shaft, and a receiving groove is fixedly provided at the top of the centrifugal disc.

[0019] It can be seen that in the above technical solution, while the centrifugal disc is rotating, the rotating roller can rotate in the receiving groove at the top of the centrifugal disc to play a guiding role in the rotation of the centrifugal disc, so as to prevent the problem of position deviation of the centrifugal disc after long-term use.

[0020] Optionally, in a possible implementation, support columns are fixedly provided at the four corners of the bottom end of the workbench, and universal wheels are fixedly provided at the bottoms of the four support columns.
