Description

TECHNICAL FIELD

[0002] In the field of chemical analysis and laboratory detection, the accurate determination of the boron content of nickel alloy is a crucial task, which is directly related to the evaluation of material performance and the quality control of subsequent application. During the detection of the boron content of nickel alloy, accurate titration operation is crucial.

[0003] Traditional titration devices often focus only on the basic placement and titration function of the burette and the conical flask, while ignoring the significant impact of solution stirring and the stability of the conical flask during operation on the accuracy of the test results. In the past, manual stirring or simple mechanical stirring methods were used for solution stirring. Manual stirring cannot guarantee uniformity and consistency, and may cause inconsistent mixing of the solution due to differences in human operation, thereby affecting the completeness and accuracy of the titration reaction. Although mechanical stirring has some improvements, the complex transmission structure not only increases the cost and maintenance difficulty of the device, but also may cause faults due to mechanical part wear, loose connection, etc., reducing the reliability of the experiment. At the same time, in the fixation of the conical flask, the traditional method is usually simply placed on the experimental table, lacking effective fixation means. During titration, especially during stirring, the conical flask is prone to shaking and displacement due to external slight vibration or stirring force, which may cause inaccurate titration liquid drop position, and even cause solution splashing, seriously affecting experimental safety and result accuracy.
