AI Technical Summary
When using existing EP tubes to pick up samples at an angle, it is difficult to easily control the optimal tilt angle, which makes it difficult to pick up the liquid or cause it to spill, affecting the experimental operation.
A vertical drainage column is installed inside the EP tube, located at a 45° clockwise direction with the center of the tube body as the center and the connection point as the starting point. The bottom is connected to the bottom of the tube, and the head is slightly lower than the tube opening. When the tube cap is closed, it is level with the tube cap and is used to guide the liquid out.
It enables easy control of the optimal angle for liquid outflow when tilted, avoiding liquid spillage, reducing residue, and improving sample absorption efficiency.

TECHNICAL FIELD
[0001] The utility model belongs to the technical field of test tools, especially an EP tube convenient to use in the state of inclination. BACKGROUND
[0002] EP tube stores sample and has the advantages of convenience and low cost, and is widely used in various test work. When the EP tube is long or the liquid in the tube is less, the pipette tip cannot directly suck the liquid, and the EP tube needs to be inclined to complete the sample sucking process. The existing EP tube does not have a drainage column, and when the sample is sucked in the state of inclination, the best inclination angle of the tube body cannot be easily grasped, which makes it difficult to suck the liquid or easy to spill, affecting the experimental operation. SUMMARY
[0003] The utility model discloses a EP tube convenient to use in the state of inclination, which overcomes the shortcomings of the prior art and solves the problem that the inclination angle cannot be easily grasped when the EP tube is inclined to suck the sample, so that the liquid in the tube can be easily sucked by the tip, and the working efficiency of the experimenter is improved.
[0004] The utility model discloses a EP tube convenient to use in the state of inclination, which overcomes the shortcomings of the prior art and solves the problem that the inclination angle cannot be easily grasped when the EP tube is inclined to suck the sample, so that the liquid in the tube can be easily sucked by the tip, and the working efficiency of the experimenter is improved.
[0005] The utility model discloses a EP tube convenient to use in the state of inclination, which overcomes the shortcomings of the prior art and solves the problem that the inclination angle cannot be easily grasped when the EP tube is inclined to suck the sample, so that the liquid in the tube can be easily sucked by the tip, and the working efficiency of the experimenter is improved.
[0006] Preferably, the EP tube is a whole structure, characterized in that the EP tube comprises a tube body (1) having a connecting part (2) at the tube opening position, a tube cover (3) connected to the tube body (1) through the connecting part (2), and a vertical drainage column (4) arranged inside the tube body (1).
[0007] Preferably, the drainage column (4) is located in the clockwise 45° direction with the center of the tube body (1) as the center and the connecting part (2) as the starting point; the bottom of the drainage column (4) is connected with the bottom of the EP tube, and the head is slightly lower than the tube opening; when the tube cover (3) is closed, the head of the drainage column (4) is just as high as the bottom of the tube cover (3); the head of the drainage column (4) is provided with a circular arc guide angle.
[0008] Preferably, the EP tube is characterized in that the material of the EP tube is hard plastic.
[0009] The user holds the EP tube with the left hand, opens the EP tube cover and tilts, and the liquid in the tube can be easily mastered to flow out and be sucked at the best tilting angle under the guidance of the vertical drainage column, so that the operation is convenient and fast; and the liquid in the tube is not spilled at a large angle, and the liquid residue in the cup is also reduced, so that the sample is conveniently sucked and transferred.
