Description

Technical Field

[0001] The utility model belongs to the field of microorganism detection, and particularly relates to a test tube rack for microorganism detection. Background Art

[0002] With the frequent outbreak of food microorganism incidents, the pathogenic bacteria detection technology presents a diversified pattern. Molecular biology technologies based on DNA and RNA analysis have been favored in the field of microorganism detection. Industrial microorganism detection mainly serves the microorganism quality control of industries such as food and pharmaceuticals. The International Organization for Standardization has also begun to pay high attention to the standardization of such technologies. Among the most common detection tools in the process of microorganism detection, the use of test tubes and test tube racks is included.

[0003] Currently, a Chinese utility model with the publication number of CN211612813U relates to the technical field related to microorganism detection, specifically a test tube rack for microorganism detection, including a base and a support column arranged on the upper surface of the base. A fixed clamping block is fixedly welded above the support column. The fixed clamping block is a long rod with a rectangular cross-section. Threaded holes are opened at both ends of its rod body, and a clamping notch is opened on the front surface of its rod body. An active clamping block is arranged on the front side of the fixed clamping block. The active clamping block has the same structure as the fixed clamping block, and bolt holes are opened at both ends of its rod body. The bolt holes correspond to the positions of the threaded holes, and the two are connected and fixed by adjusting bolts; by setting the test tube placement groove on the test tube rack to be composed of a fixed clamping block and an active clamping block, and connecting the two through an adjusting bolt, the user can adjust the distance between the two clamping blocks through the adjusting bolt, so as to realize the stable fixation of test tube racks for test tubes of different specifications.

[0004] During the use of this test tube rack, since the support column and the fixed clamping block have a fixed height, although the test tube rack can clamp and place test tubes of different sizes, it cannot be adapted to test tubes of different lengths. When it is necessary to clamp and place a shorter test tube, the top of the test tube is prone to fall off between the fixed clamping block and the active clamping block. At the same time, when the residual water droplets on the test tube wall accumulate in the liquid collecting groove, it is not convenient to clean the water body inside the liquid collecting groove. After long-term accumulation of water, bacteria are easily bred, which affects the washed test tubes. Content of the Utility Model

[0005] The purpose of the utility model is to provide a test tube rack for microorganism detection, which has the advantages of being convenient for clamping and placing test tubes of different lengths, and at the same time being convenient for treating the water body on the inner wall of the test tube after cleaning, and having the function of facilitating maintenance and cleaning.
