[0002] Centrifugation technology has been widely used in biological sciences, especially in the fields of biochemistry and molecular biology research. Centrifugation technology is mainly used for the separation and preparation of various biological samples. The biological sample suspension is placed in a centrifuge tube and rotated at high speed. Due to the huge centrifugal force, the suspended tiny particles settle at a certain speed and are separated from the solution. The centrifuge tube is a tubular sample container that can be equipped with a sealing cover or a pressure cover. A centrifuge tube rack is needed to support the centrifuge tube during its placement.
[0003] When placing centrifuge tubes, the existing centrifuge tube racks can usually only place centrifuge tubes of a specific size, resulting in the need for specific centrifuge tube racks for centrifuge tubes of different specifications, resulting in a small application range of the centrifuge tube rack and insufficient utilization. When the centrifuge tubes placed on the centrifuge tube rack need to be taken, when the required centrifuge tubes are far away from the experimenter, the centrifuge tube rack is sometimes required to be moved to take the centrifuge tube on the other side of the centrifuge tube rack, resulting in inconvenience in taking. Therefore, a centrifuge tube rack that is convenient for placing and taking centrifuge tubes is proposed to solve the above-mentioned problems. Utility Model Content
