Description

Technical Field

[0001] This utility model belongs to the field of reagent rack technology, and in particular relates to a reagent rack for biological experiments. Background Technology

[0002] In biological experiments, different reagent tubes need to be allowed to stand and be observed. However, when holding the reagent tubes by hand, the temperature of the palm can affect the composition of the reagents inside, leading to errors in the experimental results. Furthermore, hand tremors can prevent the solvent inside the reagent tube from settling completely. In addition, different types of reagent tubes are required for different experiments, and ordinary test tube racks are not compatible with different types of reagent tubes. When testing biological reagents in batches, using test tube clamps to hold the reagent tubes one by one is inefficient, and holding multiple test tube clamps takes up a lot of desktop space, making it inconvenient for other operations.

[0003] To address these issues, we provide a reagent rack for biological experiments. Utility Model Content

[0004] The purpose of this invention is to provide a reagent rack for biological experiments. A set of test tube placement openings is provided on one side of a fixed base plate, and an adjustment slot is provided on the side of the fixed base plate away from the test tube placement openings. Adjustment clamps are slidably fitted into the adjustment slots. Reagent tubes that need to be placed in the test tube placement openings are then held in place by the adjustment clamps, improving the efficiency of reagent tube placement and reducing the space occupied on the desktop. The fixed base plate is rotatably installed within a vertical frame assembly, which is then vertically slidably fitted into a desktop frame. The desktop frame is placed on the desktop, and the height of the vertical frame assembly can be adjusted as needed to adjust the height of the reagent tubes, making it easier to observe the reagent tubes after they have settled.
