Abstract

This invention discloses a handheld minim titrator including a sample pin protection jacket, a titrator wrap, a core locking plug of the titrator, a sample cavity of the sample pin and the titrator, a titrator pull rod and a core characterizing that said titrator pull rod is set in the sample cavity of the sample pin and the sample titrator to make up of a core, which is set in the wrap to be locked by the plug of the core and the protection jacket of the sample pin coveres one end of the pin to form a handheld minim titrator, which can replace acid-alkali buret in the lab and is suitable for oxidation-reduction titration method.

Description

technical field [0001] The invention belongs to chemical analysis equipment, relates to a portable, quick and convenient titration equipment, in particular to a hand-held micro titrator used for quantitative detection of samples on site or in the field. Background technique [0002] As the most basic and effective chemical analysis method, titration analysis is widely used in the production process and product quality detection and analysis of food, building materials, petrochemical and other industries. According to the different chemical reactions used in the analysis, titration analysis is divided into acid-base titration, redox titration, complexometric titration, precipitation titration and non-aqueous titration. There are many types of instruments using the above-mentioned titration analysis method, but now the instruments using the above-mentioned titration analysis method must use burettes, titration stands, titration support racks and other accessories, the operatio...
