Description

Technical Field

[0001] This utility model relates to the field of dispensing device technology, and in particular to a device for convenient dispensing of liquids. Background Technology

[0002] In the process of preparing liquids in the laboratory, it is often necessary to dispense the prepared liquids according to volume after preparation. This is an important part of daily laboratory operations. Whether conducting chemical experiments, biological detection, or materials research and development, prepared liquid reagents often need to be divided into small portions of different volumes for storage or use according to the specific needs of subsequent experiments. Specific gravity determination requires a specialized hydrometer and a long-bore beaker, which is difficult to perform without the necessary equipment. This places high demands on the accuracy, efficiency, and safety of dispensing, directly affecting the reliability of subsequent experimental results and the standardization of experimental procedures.

[0003] In existing technologies, when preparing liquids in the laboratory and then dispensing them, the specific gravity of the liquid is first measured, and then the weight of a specified volume of liquid is calculated. The specified weight of liquid is then weighed using an electronic scale for dispensing. This method is relatively complex. After measuring the specific gravity, the weight needs to be calculated, which is prone to errors. During the weighing process, phenomena such as "dripping" and "leaking" are likely to occur, leading to pollution of the working environment and leakage of chemicals. Portable quantitative dispensing capabilities are relatively poor, and the dispensing is not leak-proof or convenient to operate. At the same time, existing dispensing is usually a manual operation, and the convenience of automatic mechanical control is insufficient, affecting the accuracy and convenience of dispensing and loading. Therefore, we propose a device for convenient liquid dispensing to solve the above problems. Utility Model Content
