Description

Technical Field

[0001] The utility model relates to the technical field of a centrifuge tube storage rack, and more specifically, to a centrifuge tube storage rack. Background Art

[0002] Centrifuge tubes are commonly used experimental equipment in the fields of medicine and biology, and are used for sample separation, purification and storage. In order to facilitate the storage and management of centrifuge tubes, centrifuge tube storage racks came into being. However, the existing centrifuge tube storage racks have some shortcomings in terms of test tube fixation, which affects their convenience and adaptability. Specifically, different experimental operations and sample characteristics have different requirements for the fixing strength of centrifuge tubes. For example, when dealing with some volatile or leaky samples, a larger fixing force is required to ensure the sealing of the centrifuge tube; and for some delicate or fragile samples, excessive fixing force may cause deformation or damage to the centrifuge tube, affecting the accuracy of the experimental results. However, the existing centrifuge tube storage racks usually adopt a one-size-fits-all design, and the fixing force cannot be adjusted, which is difficult to meet the needs of different experimental scenarios. Users can only passively accept the established fixing force and cannot optimize it according to actual conditions, which not only reduces the experimental efficiency, but also may bring the risk of sample loss or experimental failure.
