[0002] Electrophoresis experiment is an experimental method for separating substances. This method separates atoms, molecules, cells and other molecules in a mixture through the action of an electric field, so as to obtain a sample with high purity.
[0003] Electrophoresis experiments can be used to separate biological macromolecules such as DNA, RNA, and proteins, and can also be used to separate organic substances such as drugs and cosmetics. In the biological field, electrophoresis experiments are often used to study microscopic structures such as genes, human cells, and bacteria, so as to find new drugs or treatment plans.
[0004] Electrophoresis experiment is one of the important separation technologies in the fields of modern biology and chemistry, and its application scope is wide. With the development of fields such as molecular biology and biotechnology, electrophoresis experiments play an increasingly important role in research, and its technology has been continuously improved and developed.
[0005] In the existing electrophoresis experiments, manual coating is mainly used. This method is not convenient for the standardized operation of the experiment. When adding reactants, it is easy to cause uneven addition of reactants and insufficient reaction. Summary of the Utility Model
[0006] In view of this, to solve the technical problem that in the existing electrophoresis experiment, when manually coating reactants, it is easy to cause uneven addition of reactants, resulting in insufficient reaction, the utility model provides an electrophoresis mask device, which opens adding holes on a mask plate and communicates with the openings on a mask strip. The liquid falls into the mask strip through the adding holes, and under the action of surface tension, the liquid uniformly diffuses along the mask strip, so as to achieve the purpose of uniformly adding reactants.
[0007] To achieve the above object, the utility model provides the following technical solutions:
[0008] An electrophoresis mask device, comprising:
[0009] A mask plate, on which a plurality of adding holes are opened;
[0010] A mask frame, which is arranged on the side with a smaller opening of the adding hole and plays a supporting role;
[0011] A mask strip, which is a guide groove, and a through hole for communicating with the smaller opening end of the adding hole is opened on the back of its opening;
[0012] A height difference is formed between the mask frame and the mask strip, and the height of the mask strip is lower than the height of the mask frame;
[0013] Liquid enters the guiding groove from the adding hole and diffuses evenly within the guiding groove.
[0014] Preferably, it further includes:
[0015] A positioning device, which is arranged at the bottom of the mask plate and is used to accurately place the mask plate above the film.
[0016] Preferably, it further includes:
[0017] A handle, which is arranged on the upper part of the mask plate.
[0018] Preferably, the adding hole is at least one of a conical hole, a circular hole, a square hole and an irregular hole.
[0019] Preferably, the adding hole is a conical hole.
[0020] Preferably, the height difference between the mask frame and the mask strip is 0.05 mm to 5 mm.
[0021] Preferably, the height difference between the mask frame and the mask strip is 0.1 - 2 mm.
[0022] Preferably, the material of the mask device is a transparent material.
[0023] The utility model has the following beneficial effects compared with the prior art:
[0024] The electrophoresis mask device provided by the utility model opens an adding hole on the mask plate and communicates with the opening on the mask strip. Liquid (reactant) falls into the mask strip through the adding hole. Under the action of surface tension, since the mask strip is in the form of a guiding groove, the liquid diffuses evenly along the mask strip, so as to achieve the purpose of uniformly adding reactants.
[0025] Since the utility model uses an adding hole to add reactants, the diameter and depth of the adding hole determine the volume of liquid that can be stored, and the diameter and depth of the adding hole can be set according to the actual amount of reactants to be added. The volume formed by the width of the mask strip and the height difference from the mask frame is adapted to this, thus ingeniously solving the problem of controlling the addition amount of reactants.
[0026] The bottom of the mask plate of the utility model is provided with a positioning device, so that the user can conveniently and accurately place the mask plate above the film. No handle is arranged on the mask plate, which can prevent the user from touching the film when taking the mask plate. At the same time, the position distribution of the adding holes on the mask plate is provided with a first hole position anti-fooling setting, which is more user-friendly and can prevent wrong addition.
[0027] In summary, when using the device of the present utility model to uniformly add reactants on the film lane, the reactant addition method is convenient, the reactant coating is uniform, and the reaction is sufficient. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Such as Figures 1-4As shown, the present utility model provides an electrophoresis mask device, comprising:
[0037] A mask plate 1, on which a plurality of adding holes 11 are provided. The adding holes 11 have one end with a large opening and one end with a small opening.

It shows that the mask frame 2 is preferably rectangular and is arranged on the left and right sides of the mask plate 1.
[0039] It should be noted that the shape of the mask frame 2 is not limited to a rectangle, not limited to the left, right, front, and back sides of the mask plate, and can also be set as a column shape and placed in the middle position of the mask plate 1;
