Magnetic cleaning brush of volumetric flask

Abstract

The invention discloses a magnetic cleaning brush of a volumetric flask. The magnetic cleaning brush adopts a structure provided with an inner brush and an outer brush, the two brushes are connected with each other inside and outside a flask body by magnetic force, and the outer brush is used for controlling the inner brush to move outside the flask body, so that the volumetric flask is cleaned conveniently, and the inside and the outside of the volumetric flask can be cleaned simultaneously; in addition, the two brushes are made of soft materials and adopt a special structure, so that a brush body is bent easily, and the volumetric flask can be cleaned seamlessly without dead angle. Materials of all parts on the two brushes cannot be rusted, so that the service life of the magnetic cleaning brush is obviously longer than that of the traditional brush.

Description

technical field [0001] The invention relates to the technical field of experimental instruments, in particular to a volumetric flask magnetic cleaning brush. Background technique [0002] The volumetric flask is a precise instrument for preparing a solution with an accurate concentration of a certain substance, and it is an indispensable glassware in the laboratory. It is a slender necked, pear-shaped, flat-bottomed glass instrument with a ground glass stopper. Because the bottle mouth is slender and the bottle body is thick, it is not easy to clean the bottle body. Especially the large pear-shaped bottle body is prone to inconvenient cleaning or residual magazines after cleaning, which not only affects the operation progress of the experimenters and the accuracy of subsequent experiments, but also increases the number of cleaning times, wasting water resources and operating time .

Problems solved by technology

Because the bottle mouth is slender and the bottle body is fat, it is not easy to clean the bottle body

Especially the large pear-shaped bottle body is prone to inconvenient cleaning or residual magazines after cleaning, which not only affects the operation progress of the experimenters and the accuracy of subsequent experiments, but also increases the number of cleaning times, wasting water resources and operating time

[0003] At present, most of the existing cleaning brushes for volumetric flasks use ordinary test tube brushes or their improved brushes. The structure is relatively simple, the cleaning is not thorough, and the brush bracket is prone to rust, which affects the service life.
