Description

Technical Field

[0001] The utility model belongs to the technical field of laboratory instruments and equipment, and particularly relates to an annular bracket for placing detachable titration pliers for acid-color and alkali-color burettes. Background Technique

[0002] In chemical experiments, titration is a commonly used quantitative analysis method for determining the concentration of a certain substance in a solution. Titration operations usually require the use of burettes to add titration reagents drop by drop until the color change at the titration endpoint indicates the completion of the reaction. Therefore, the placement and fixation of burettes are crucial for the accuracy and efficiency of titration operations.

[0003] In traditional titration operations, burettes are usually held by hand or placed on a test tube rack. However, when performing multiple titration operations simultaneously, holding the burette by hand may cause instability, and the fixing method on the test tube rack may not meet the requirement of placing multiple burettes at the same time;

[0004] The existing burette bracket designs are mostly linear, which can only place one or two burettes and cannot meet the requirement of performing multiple titration operations simultaneously. In addition, the way some brackets fix the burettes may not be firm enough, easily causing the burettes to tilt or fall down, affecting the accuracy of titration operations.

[0005] Therefore, an annular bracket for placing detachable titration pliers for acid-color and alkali-color burettes is proposed. Content of the Utility Model
