[0002] Magnetic racks are widely used in various experiments in laboratories, especially in biological and medical experiments, such as nucleic acid extraction and cell sorting. Because different experiments have different requirements for the specifications of magnetic racks, laboratories need to purchase different specifications of magnetic racks according to their experimental needs, resulting in high procurement costs. Furthermore, the need to replace magnetic racks of different specifications multiple times during experiments makes the experimental process more complex and hinders rapid response to experimental needs.

[0003] Therefore, how to provide an adjustable electromagnetic force frame to improve the compatibility and ease of use of the magnetic force frame, and reduce the procurement cost of the magnetic force frame, has become an urgent technical problem to be solved. Summary of the Invention

[0005] This utility model is implemented as follows: an adjustable electromagnetic force frame, comprising:

[0006] The device includes a magnetic frame body, four replaceable connectors, a base, a power supply, a switch, a sliding rheostat, and an electromagnetic coil. The upper end of the magnetic frame body has an internal thread section, and the lower end is fixedly connected to the base. Each replaceable connector includes a support column, a base, and a test tube storage slot. The top end of the support column is fixedly connected to the bottom end of the base, and the outer wall of the support column has an external thread section that matches the internal thread section. The test tube storage slot is located at the top of the base and can be a 4-hole, 12-hole, 36-hole, or 96-hole test tube storage slot. The power supply, the switch, the sliding rheostat, the electromagnetic coil, and the power source are connected in series, and the electromagnetic coil is wound around the outer wall of the magnetic frame body.

[0007] Furthermore, a galvanometer is also provided, with one end of the galvanometer connected to the power supply and the other end connected to the switch.

[0008] Furthermore, the main body of the magnetic frame is a metal frame.

[0009] Furthermore, the power supply is located on one side of the base, while the switch, the sliding rheostat, and the ammeter are all located on the other side of the base.

[0010] Furthermore, the adjustable range of the sliding rheostat is 50-500Ω.

[0011] The advantages of this utility model are:

[0012] 1. By setting up a power supply, a switch, a sliding rheostat, an electromagnetic coil, and a galvanometer, based on the principle of electromagnetic induction, the main body of the magnetic rack and the replaceable connectors are made magnetic. By setting up a main body of the magnetic rack and four replaceable connectors, an electromagnetic rack that can hold test tubes of different sizes can be obtained by replacing the replaceable connectors on the main body of the magnetic rack. Unlike traditional methods, there is no need to replace the whole thing. Moreover, the laboratory only needs to purchase one electromagnetic rack to meet the needs of different sizes of magnetic racks. Even if it cannot meet the needs, only the corresponding replaceable connectors need to be purchased. Unlike traditional methods, there is no need to purchase the whole thing. Ultimately, this greatly improves the compatibility and ease of use of the magnetic rack and greatly reduces the procurement cost of magnetic racks in the laboratory.
