Titrator applied to teaching and operating method thereof

Abstract

The invention relates to a titrator used in teaching and an operation method thereof. The titrator used in teaching includes a casing connected with a peristaltic pump for infusion power. The casing is provided with a cavity, and a receiving chamber is provided in the cavity. It is a control system that instructs and controls the operation of the instrument. The upper end of the case is provided with a display screen showing the operation process and test results, and the side end of the case is provided with a height-adjustable and detachable bracket. The output end of the peristaltic pump is connected to a The disassembled pump tube, the upper end of the pump tube is connected to the bracket, the titration curve is set in the control system, the display screen and the peristaltic pump are electrically connected to the control system respectively. In the present invention, the titration curve is set in the control system and displayed on the display screen in real time during the titration process, so that the titration process can be displayed more vividly in the titration teaching, the bracket can be disassembled, and the height can also be adjusted within a certain range. Lightweight, simple structure design, strong and durable, low cost.

Description

technical field [0001] The invention relates to a teaching tool, more specifically a titrator used in teaching and an operation method of the titrator used in teaching. Background technique [0002] In addition to potentiometric titration, including acid-base titration, redox titration, precipitation titration, complexometric titration and non-aqueous titration, the titrator can also perform constant pH measurement. Optional titration analysis methods such as photometric titration, polarization titration, volumetric Karl Fischer titration and surfactant titration can be performed. When the automatic titrator is used online with the automatic multi-sample converter, it can not only efficiently realize the automatic measurement of a large number of samples, but also improve the repeatability and reliability of the analysis, and the operation is simple, saving time and effort. Applicable to quality control, inspection, analysis, research, development and other aspects. [000...

AI Technical Summary

Problems solved by technology

[0003] The traditional teaching titration device is a device with a burette and an iron stand. Its disadvantages are: it needs to be cleaned manually; the glass material is easily damaged; in the actual teaching process, most of the students are in contact with it for the first time, and it is easy to cause teaching accidents or damage teaching equipment.

[0005] Whether it is a traditional titration device or a fully automatic large-scale titration device, it cannot achieve the purpose of guiding students to learn theoretical knowledge, and it is even more inconvenient to combine with the teacher's theory and practice in actual teaching experiments.
