Description

Technical Field

[0001] The utility model relates to the technical field of sample adding devices, in particular to a gel electrophoresis sample adding device. Background Art

[0002] In molecular biology experiments, gel electrophoresis is a particularly common device. Its principle is that after power is turned on, DNA with different molecular weights travels different distances per unit time, thereby identifying different genes. During the agarose experiment, a sample loading device is needed to load the sample.

[0003] In the process of adding samples in the existing device, when the sample shakes slightly, it will affect the stability of the addition and the filling time. Although there are automatic sample adding devices at present, when the electric drive parts of the automatic sample adding device, such as the motor, are damaged, it needs to be repaired before continuing to add samples, which has low practicality. Utility Model Content

[0004] In view of this, the utility model provides a gel electrophoresis sample loading device, which solves the problem that when the sample is slightly shaken during the loading process of the existing device, the loading stability and the loading time will be affected, as well as the problem of low practicality.

[0005] The purpose and effect of the gel electrophoresis sample adding device of the utility model are achieved by the following specific technical means:

[0008] Furthermore, the two limiting rods are both cylindrical rod-shaped structures, and the upper ends of the two limiting rods are polished. After polishing, the upper ends of the two limiting rods are both arc-shaped structures, which will be smoother and more convenient when the sample holder and the two limiting rods are plugged in.

[0009] Furthermore, two handles are symmetrically welded on the top surface of the sample holder, and the tops of the two handles are higher than the top surface of the electrophoresis box.

[0011] Furthermore, the second threaded rod is rotatably connected to the electrophoresis box, and a second connecting block is threadedly connected to the second threaded rod. The second connecting block is a rectangular block structure, and the second connecting block is slidably connected to the mounting block. The mounting block is threadedly connected to two locking screws for locking the first connecting block and the second connecting block.

[0012] Furthermore, two supporting blocks with rectangular block structures are symmetrically fixed to the bottom end surface of the electrophoresis box, and both supporting blocks are in contact with the workbench.
