Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bio-based materials, in particular to a solution titration device for the research and development of bio-based materials. Background Technique
[0002] Titration refers to a means of quantitative analysis and also a chemical experiment operation. It determines the content of a certain solute through the quantitative reaction of two solutions. It indicates the titration end point according to the color change of the indicator, and then visually observes the consumed volume of the standard solution to calculate the analysis result. A burette is a measuring device for containing the titrant solution in titration operations. A burette is a slender glass tube with a uniform inner diameter and scale. There is a glass tip at the lower end of the tube, and it has different volumes such as 25 ml and 50 ml. The main part of the burette, the tube body, is made of a glass tube with a uniform inner diameter and precise scale. The lower end is connected to a glass stopcock for controlling the liquid outflow rate or a latex tube containing glass beads, and the bottom end is further connected to a pointed glass tube. A burette with a glass stopcock at the lower end is called an acid burette and is commonly used to measure the volume of non-strong alkaline dilute solutions dropped out.

However, during the experiment, when the operator needs to adjust the height of the burette, the operator needs to loosen the locking bolt, then move the butterfly clip up or down, and then fix the butterfly clip at an appropriate height. When the operator moves the butterfly clip up and down, it is easy to make the burette shake, and then it is easy to make the chemical agent in the burette splash out. Therefore, it is necessary to design and transform the solution titration device for the research and development of bio-based materials to effectively prevent the phenomenon of inconvenient adjustment.
