Description

Technical Field

[0001] The utility model relates to the technical field of punching devices, in particular to a bidirectional agar diffusion plate punching device. Background Art

[0002] The bidirectional agar diffusion test is an experimental method used to measure the diffusion rate of a solute in agar. In this experiment, an agar block is cut in half, and a solute is added to one half. Over time, the solute diffuses from the high-concentration area to the low-concentration area, forming a gradient with gradually decreasing solute concentration. By observing this diffusion process, the diffusion rate of the solute in the agar can be determined. Soluble antigens and corresponding antibodies are used as carriers in agar. Under appropriate conditions, the antigens and antibodies combine to form a visible precipitate. This test is widely used in biology, biochemistry, and other scientific fields to study the diffusion characteristics of solutes under different conditions and the laws of molecular motion in agar.

[0003] When conducting bidirectional agar diffusion experiments, a puncher is required to create a diffusion gradient between high- and low-concentration areas. Existing punchers are hollow cylinders that require a needle to remove the agar, a step that can easily damage the integrity of the agar plate. Furthermore, different experimental projects require different numbers of holes, necessitating the preparation of multiple punchers with different hole sizes, making the experimental process time-consuming and labor-intensive.
