Referring to fig. 7 and 8, the tank 3 of the present application includes an outer cylinder 4 and an inner cylinder 5 made of an insulating material, with a gap 18 communicating between the side and bottom of the outer cylinder 4 and the side and bottom of the inner cylinder 5. The side wall of the outer cartridge 4 comprises an inlet 9 and an outlet 10 through which a fluid (e.g. hot water at 30 c) can enter the gap 18 and can leave the gap 18 through the outlet 10. Preferably, fluid is able to circulate in said gap 18 through said inlet 9 and outlet 10. Preferably, the inlet 9 is arranged at a lower level than the outlet 10 to facilitate venting when fluid enters the gap 18.

This application adopts the electrophoresis tank of binocular to compare with the single electrophoresis tank that uses among the prior art has following advantage:

1. the spiral heating rod used in the prior art can be omitted, and the gap between the double cylinders can be used for passing heating fluid to replace the spiral heating rod, so that the spiral heating rod does not need to be cleaned when the electrophoresis tank is used;

2. the efficiency of electrophoresis operation can be improved, for example, after the previous electrophoresis operation is finished, the inner cylinder can be taken out, and the next electrophoresis operation is replaced by a new inner cylinder while cleaning, so that the inner cylinder does not need to be cleaned and then subjected to the next electrophoresis operation.

The outer cylinder 4 and the inner cylinder 5 are connected by a screw 21, preferably the connection between the outer cylinder 4 and the inner cylinder 5 is a watertight or airtight connection.

Preferably, as shown in fig. 7 and 8, the upper portion of the inner cylinder 5 has a wall thickness greater than that of the lower portion, so that the thicker upper portion is available for connection to the outer cylinder 4 and to an adapter 19, described below, the thinner lower portion facilitating heat exchange of the electrophoretic fluid in the inner cylinder 5 with the heating fluid in the gap 18.

Preferably, as shown in fig. 1, 5 and 6, the outer cylinder 4 and the inner cylinder 5 are cylindrical. The cylindrical inner and outer cylinders are easier to clean than the square electrophoresis tanks of the prior art because the cylindrical shape has fewer corners.

Fig. 6-8 show a fixture 11, said fixture 11 being made of an electrically conductive material, such as metal, for arranging a cathode plate (not shown) to be coated in said tank 3, said fixture 11 being in electrical communication with said cathode plate. The jig 11 has a structure known to those skilled in the art and has an H shape, and thus is not described in detail herein. When the jig 11 is disposed in the tank 3, the jig 11 protrudes from the upper surface of the tank 3. The top cover 2 comprises a recess 12 for receiving the clamp 11, and the shape of the recess 12 is adapted to the shape of the clamp 11, so as to achieve a correct positioning of the top cover 2, as will be described in more detail below. For example, the recess 12 of the top cover has a rectangular parallelepiped shape as shown in the drawing.

As shown in fig. 4 and 6, the tank body includes an anode plug 7 and a cathode plug 8, the anode plug 7 is electrically connected to the anode plate 6, the cathode plug 8 is electrically connected to the cathode plate, the anode plug 7 and the cathode plug 8 are mated and electrically connected to corresponding insertion holes 22 of the top cover, and the insertion holes 22 are electrically connected to the electric wires 14.

Preferably, the anode plugs 7 and the cathode plugs 8 are arranged alternately around the circumference of the tank body 3 uniformly, for example, two anode plugs 7 and two cathode plugs 8 are provided, respectively. The top cover 2 comprises the same number of receptacles 22 as the anode and cathode plugs, for example the embodiment in the figure comprises four receptacles 22. Preferably, the receptacle 22 comprises a resilient tab, so as to be able to engage tightly with the

plug

7, 8. Preferably, the lower end of the receptacle 22 comprises a guiding means, e.g. a ramp, to facilitate guiding the

plugs

7, 8 into the receptacle 22.

As shown in fig. 2, 7 and 8, the top cover 2 includes a hole 13, and the electric wire 14 is inserted into the top cover 2 through the hole 13 and electrically connected to the corresponding jack 22, thereby connecting the positive and negative poles of the dc power source to the corresponding jack 22, respectively.

As is apparent from the above description, the electric wires 14 of the electrophoresis tank 1 of the present application are provided in the top cover 2, and therefore the tank body 3 is not connected to the positive or negative electrode of the power source. Therefore, when the top cover 2 is removed from the tank 3, the tank 3 is in a physical power-off state, no electric shock hazard exists for the operator, and the tank 3 is not limited by the electric wire 14 and can be moved arbitrarily.

Referring to fig. 7 and 8, when the caliber of the tank body 2 is large, the tank body 3 may include an adapter 19 made of an insulating material, and the anode plug 7 and the cathode plug 8 are disposed on the adapter 19. The anode plate 6 may also be disposed in the tank 2 through the adapter 19. As shown in the drawing, the anode plate 6 has an L shape, one end of which can be hooked on the adapter 19 and electrically connected to the anode plug 7. Preferably, one end of the anode plate 6 hooked on the adapter 19 is further fixed to the adapter 19 by a screw.

As shown in fig. 6, the jig 11 can be mounted on the adapter 19. The adapter 19 comprises a contact 20 in the vicinity of the cathode plug 8, which contact 20 is electrically connected to the cathode plug 8. When the jig 11 is mounted on the adapter 19, the jig 11 made of an electrically conductive material is electrically connected to the contact 20, so that the jig 11 is in electrical communication with the cathode plug 8. As shown in the figure, a plurality of contacts 20 may be provided on the adapter 19 according to the structure of the jig 11.

As described above, the shape of the recess 12 is matched with the shape of the jig 11, thereby achieving the positioning of the top cover 2. Still referring to fig. 6, the jig 11 has a substantially rectangular shape in plan view, with long sides respectively facing the two anode plugs 7 on the adapter 19 and short sides respectively facing the two cathode plugs 8 on the adapter 19. Referring to fig. 7 and 8, the recess 12 of the top cover 2 is substantially rectangular, so that the top cover 2 can be correctly covered on the slot 3 only when the long side of the recess 12 corresponds to the long side of the clamp 11, thereby achieving correct positioning of the top cover 2. Whereas if rotated 90 ° from the correct positioning, the jig 11 cannot be accommodated in the recess 12 when the long side of the recess 12 corresponds to the short side of the jig 11, and thus the top cover 2 cannot be properly covered on the tank 2, and the top cover 2 cannot be properly positioned. The recess 12 of the top cover 2 has a rectangular shape in a bottom view, and the rectangular long sides of the recess 12 are respectively opposite to the two insertion holes 22 connected with the positive electrode of the power supply on the top cover 2, and the short sides are respectively opposite to the two insertion holes 22 connected with the negative electrode of the power supply on the top cover 2, which are the same as the corresponding relation between the rectangular clamp 11 and the anode plug 7 and the cathode plug 8. Thus, when the clamp 11 is received in the recess 12 of the top cover 2, and therefore the top cover 2 is correctly covered on the tank 3, the positive pole of the power supply can be connected to the anode plug 7 and the negative pole of the power supply can be connected to the cathode plug 8, so that the correct positioning of the top cover 2 on the tank 3 is achieved by the shape of the recess 12 matching the shape of the clamp 11.

As shown in fig. 7 and 8, the adaptor 19 is fixedly connected to the upper surface of the inner cylinder 5. As known to those skilled in the art, various mechanisms may be provided between the adapter 19 and the inner barrel 5 to effect a fixed connection therebetween, such as a rotational locking structure, a male-female structure, a threaded structure, etc.

As shown in fig. 1-8, the top cover 2 has a top cover handle 15, the tank has a tank handle 16, and the clamp 11 has a clamp handle 17 for ease of handling and operation.

The top cover 2, the outer cylinder 4, the inner cylinder 5, and the adapter 19 of the present application are all made of an insulating material, such as polytetrafluoroethylene.
