Description

TECHNICAL FIELD

[0001] The utility model relates to biological experiment equipment technical field, especially a kind of centrifugal tube cluster device for biological experiment. BACKGROUND

[0002] Centrifugal separation technology is widely used in biomedical experimental research, and cell collection, sedimentation separation and other purposes can be achieved with the help of centrifugal force. During the centrifugal experiment, multiple resuspension, washing, centrifugal collection and other operations are often involved to achieve the purpose of purifying the precipitate. In cytogenetic research, the cultured cells need to be washed and fixed multiple times, and the cell precipitate needs to be re-mixed at each step. In biochemical experimental research, the centrifugally separated biological macromolecules (such as nucleic acids and proteins) often need to be washed to remove impurities.

[0003] In actual biological experiments, multiple centrifugal tubes are often needed. Currently, the industry generally uses centrifugal tube racks to store a certain number of centrifugal tubes. The centrifugal tube racks are usually fixed on the desktop and use the perforations on the upper and lower support plates to fix the centrifugal tubes. This structure requires careful alignment of the holes from top to bottom when storing the centrifugal tubes. If the centrifugal tubes are made of glass, they can easily break due to accidental bumps. In addition, when moving the centrifugal tubes, both hands are needed to hold the entire centrifugal tube rack, and the centrifugal tubes can easily collide with the support during transportation.
