Description

Technical Field

[0001] The utility model relates to the technical field of test tubes, in particular to a liquid-taking test tube swing rack. Background Art

[0002] A large number of experimental instruments are often used in experiments, and a test tube rack is one of them. A test tube rack is a laboratory equipment used to support and fix test tubes. The existing test tube rack has a simple structure, and the number of test tubes that can be placed is fixed. The number of racks cannot be increased or decreased according to experimental requirements. In addition, the test tube placement holes opened on the placement plate are mostly of fixed size. When a test tube with a hole diameter smaller than the placement hole is placed, there will still be a gap.

[0003] When the existing liquid collection test tube swing rack is actually used, the test tube will shake during transportation, which is easy to damage the test tube, and it is not convenient to improve the preservation and quality of the sample.

[0004] After searching the existing patents: an anti-shaking liquid test tube swing rack (publication number: CN219647556U), the utility model arranges an adjustment block inside the test tube slot. When placing test tubes of different sizes, the size of the test tube slot aperture can be adjusted by pulling the pull rod to fill the gap between the placed test tube and the test tube slot, so that when the first test tube rack body moves, it will not cause a large shaking feeling to the test tube placed in the test tube slot.

[0005] Although the above patent reduces the shaking of the test tube, the sample needs to be refrigerated at low temperature during the storage of the sample test tube to ensure the purity of the sample. Without a refrigeration device, it is not convenient to extend the storage time of the sample.

[0006] Therefore, it is necessary to invent a liquid taking test tube swing stand to solve the above problems. Utility Model Content
