An inflatable volumetric bottle brush

Abstract

The invention belongs to the field of biochemistry instruments, and particularly relates to an inflatable volumetric flask brush. The inflatable volumetric flask brush facilitates cleaning, is through in cleaning and free of dead angles, reduces brushing frequency, saves water resources and improves experiment precision. The inflatable volumetric flask brush can be used for a long time, when an air bag brush head is damaged, it is only needed that the damaged air bag brush head is replaced with a new one, operation is convenient and fast, work efficiency is improved, and resources are saved. The brush head and a brush handle are freely combined and can be freely assembled as required, the brushing requirements of the category of glassware, with the bottle neck long and the bottle body large, such as volumetric flasks, conical flasks, wide-mouth bottles and funnels in different specifications can be met, and the air bag brush head is convenient to detach and cleaned independently. The brush handle of the inflatable volumetric flask brush can be held by a cleaning worker more easily compared with a common iron handle brush, operation is easy, and cleaning is facilitated better.

Description

technical field [0001] The invention belongs to the field of biochemical instruments, in particular to an inflatable volumetric bottle brush. Background technique [0002] In the laboratory, glass containers, such as volumetric flasks and conical flasks, are often used to prepare and store solutions. For scrubbing of glass containers such as volumetric flasks and conical flasks, ordinary test tube brushes are often used. , Often the container cannot be cleaned thoroughly. Especially when cleaning the volumetric flask, because the bottleneck at the upper end of the volumetric flask is very thin and the brush is too large, it gets stuck, causing inconvenient cleaning or residual residues after cleaning, which not only affects the operation progress of the experimenters and the accuracy of subsequent experiments, And increased cleaning frequency, wasted water resource and operation time. Contents of the invention [0003] The object of the present invention is to provide an...

[0002] In the laboratory, glass containers, such as volumetric flasks and conical flasks, are often used to prepare and store solutions. For scrubbing of glass containers such as volumetric flasks and conical flasks, ordinary test tube brushes are often used. , often the container cannot be cleaned thoroughly

Especially when cleaning the volumetric flask, because the bottleneck at the upper end of the volumetric flask is very thin and the brush is too large, it gets stuck, causing inconvenient cleaning or residual residues after cleaning, which not only affects the operation progress of the experimenters and the accuracy of subsequent experiments, Moreover, the number of cleanings is increased, wasting water resources and operating time
