Description

[0002] Electrophoresis refers to the phenomenon that charged particles in a solution move in an electric field towards the electrode with the opposite charge to their own. Biological macromolecules (such as proteins, polysaccharides, nucleic acids, etc.) are often dispersed in a solution in the form of particles, and their static charges depend on the H+ concentration of the medium or the interaction with other macromolecules. Under certain pH conditions, they will inevitably be attracted by the electrode with the opposite electric charge and move in a direct current electric field. The moving speed of particles of different substances in an electric field is related not only to their charged state and electric field strength, but also to the size, shape of the particles and the viscosity of the medium. According to this characteristic, electrophoresis can be used to qualitatively or quantitatively analyze different substances, or to analyze the components of a certain mixture or extract and prepare individual components.

Among them, a positive electrode 16 is installed in each lower electrophoresis sub-tank 111, a lower negative electrode 9 and an electrophoresis anode 10 are also installed on the lower tank body 11. The electrophoresis anode 10 is electrically connected to the positive electrode 16, and the lower negative electrode 9 and the electrophoresis anode 10 are respectively plugged and electrically connected to the socket 12. Two rows of sample tubes are symmetrically installed in each upper electrophoresis sub-tank 51, and a positive electrode 16 is installed between the two rows of sample tubes. The positive electrode 16 is electrically connected to the electrophoresis anode 10. The sample tube 8 penetrates the upper tank body 5 and inserts into the lower electrophoresis sub-tank 111, and is hermetically connected to the upper tank body 5 through a sealing plug 6.

[0031] Multiple upper electrophoresis sub-tanks 51 of the upper tank body 5 correspond one-to-one with multiple lower electrophoresis sub-tanks 111 of the lower tank body 11. The upper electrophoresis sub-tanks 51 and the lower electrophoresis sub-tanks 111 are filled with buffer solution 17. The number of the upper electrophoresis sub-tanks 51 and the lower electrophoresis sub-tanks 111 can both be 1, 2, 3, 4, 5, 6, 7, 8, 9 or 10, etc. Of course, it is not limited to this, and the appropriate number of electrophoresis sub-tanks can be selected according to needs.

[0038] As Figure 3As shown, at least two independent lower electrophoresis sub-tanks 111 are formed in the lower tank body 11 by separating with a lower partition plate 112. The lower partition plate 112 seals and separates each lower electrophoresis sub-tank 111, and there is no communication between adjacent lower electrophoresis sub-tanks 111, so that the buffer solutions in each lower electrophoresis sub-tank do not flow through each other.

[0047] The number of upper electrophoresis sub-tanks 51 formed by separating the upper tank body 5 with the upper partition plate 52 is 2, 3, 4, 5, 6, 7, 8, 9, 10, etc. Of course, it is not limited to this, and a suitable number of upper electrophoresis sub-tanks can be selected according to needs.

The lock body 26 is provided with a lock opening 261 and is hinged to the lock base 25. The lock tongue 103 is installed on the tank cover 1, and the lock body 26 is swingably engaged with the lock tongue 103 through the lock opening 261.

[0053] As Figure 6 shown, an installation structure of the lock tongue is given. The tank cover 1 is provided with a groove 101. The groove 101 is provided with a support body 102 extending downward for installation, and a lock tongue 103 is installed at the bottom of the support body.

After the buckling is in place, the locking body 26 is swung upward, and the locking opening 261 on the locking body is sleeved on the locking tongue, realizing the socket connection and fixation between the locking body and the locking tongue, so that the groove cover and the upper groove body are locked and connected through the locking fastener.

[0055] As Figure 4 shown, a limiting plate 104 and a groove cover rib plate 105 are also installed on the groove cover 1. The limiting plate 104 is installed near the edge of the groove cover. When the groove cover is buckled on the upper groove body 5, the limiting plate 104 is inserted into the upper groove body to limit the installation position of the groove cover. A plurality of groove cover rib plates 105 are installed at intervals and in parallel between adjacent groove cover electrode plates.
