Description

Novel chemistry titration device

Technical Field

The utility model belongs to the technical field of titration apparatuses, and particularly relates to a novel chemical titration device.

Background

Chemical titration is a quantitative analysis means in analytical chemistry and is also one of the most common chemical experimental procedures. The basic principle is to use the quantitative reaction of two solutions to determine the quality of a certain solute, indicate the titration end point according to the color change of an indicator, then visually observe the consumption volume of the standard solution, and calculate the analysis result.

A typical index value for a 25mL or 50mL burette is 0.1mL, i.e., 0.1mL precision. When the epoxy equivalent or isocyanate content is measured by a chemical titration method, the blank volume and the actual consumption volume are respectively titrated, and the final result is obtained by calculating the difference value of the blank volume and the actual consumption volume. Under such circumstances, after the reading errors are superimposed, the influence on the accuracy of the result is very large, the accuracy of the conventional burette cannot be further improved, and large experimental deviation often occurs.

In summary, the present utility model provides a novel chemical titration apparatus to solve the above problems.
