Description

Technical Field

[0001] The invention belongs to the field of test equipment, and in particular relates to a container diversion device. Background Art

[0002] In laboratory testing, some small-caliber containers are often used. For example, the detection of ammonia nitrogen in water quality uses a 10mL colorimetric tube with a diameter of 8mm, and the detection of available phosphorus in soil uses a 50ml volumetric flask with a diameter of 10mm. Due to the surface tension of the liquid at the mouth of the container, it is difficult for the liquid in the container to flow out through a small-caliber pipe. During the operation, the liquid needs to be poured into a cuvette for the next step of testing, and the liquid needs to flow into the cuvette smoothly and steadily. In actual operation, the liquid is not easy to flow out, and the experimenter needs to shake the container. At this time, the liquid will suddenly gush out in large quantities, causing the outer wall of the cuvette to be covered with liquid, which is very inconvenient to operate. Summary of the invention

[0003] In view of this, the present invention aims to propose a container diversion device to solve the technical problem that when the container is tipped, the liquid in the container is difficult to flow out through a small-diameter pipe due to the surface tension of the liquid at the mouth of the container.
