Description

Technical Field

[0001] The utility model relates to the technical field of biological centrifuges, in particular to a biological centrifuge device. Background Art

[0002] The working principle of a biological centrifuge is to use the centrifugal force generated by high-speed rotation to separate components such as cells, proteins, and DNA in a sample to different positions due to different densities. This device has extensive applications in the fields of biomedical research, drug development, genetic engineering, cell culture, etc.

[0003] The existing patent number CN218132580U discloses a multifunctional biological centrifuge, belonging to the technical field of centrifuges. It includes a biological centrifuge body, a centrifuge rotor is arranged inside the biological centrifuge body, several symmetric test tube placement grooves are opened inside the centrifuge rotor, a multi-stage rubber limit block is fixedly connected inside the test tube placement groove through a flexible control strip, an elastic support component is sleeved outside the flexible control strip, and position limiting components are fixedly connected to both sides of the biological centrifuge body. For this multifunctional biological centrifuge, by setting the test tube placement groove, multi-stage rubber limit block and shock absorption and noise reduction device, the situation that the outside of the test tube is worn due to excessive pressure can be avoided, so that the test tube can be fixed, enabling the device to limit test tubes of different sizes, thus realizing the fixation of the test tube without replacing the centrifuge rotor, with simple operation, and the shock absorption and noise reduction device can absorb the noise generated by the biological centrifuge body.

[0004] During the centrifugation process, the rotor needs to fix test tubes of different sizes. The rotor of the existing technology is of an integral fixed design and can only fix test tubes of a single size. For test tubes of different sizes, fixation can only be completed by replacing the rotor, which not only prolongs the centrifugation time but also makes the operation of the centrifugation work cumbersome.
