Abstract

The invention discloses a high precision chemical reagent blending apparatus for experiments. The upper end of a reagent tube (A) is provided with a reagent tube handle (A). The reagent tube (A) is provided with scales (A). The lower end of the reagent tube (A) is provided with a tube head. The tube head is fixedly connected to the reagent tube (A). The lower end of the tube head is provided witha delivery pipe. The middle of the delivery pipe is provided with an adjusting knob. The lower end of the delivery pipe is provided with a needle. A reagent tube (B) is arranged in the reagent tube (A). The upper end of the reagent tube (B) in the reagent tube (A) is provided with a reagent tube handle (B). The lower end of the reagent tube (B) is provided with a rubber ring (A) matched with the reagent tube (A). A reagent tube (C) is arranged in the reagent tube (B), and the lower end of the reagent tube (C) is provided with a rubber ring (B) matched with the reagent tube (B). By arranging multiple reagent tubes, the volume of an experiment instrument is enlarged, moreover, the reagent ratio becomes more precise during the chemical experiment process, the splashing of chemical reagents isprevented, and the safety of chemical experiments is guaranteed.

Description

technical field [0001] The invention relates to the technical field of chemical experiment instruments for middle school students, and more specifically relates to a high-precision experimental chemical reagent mixing device. Background technique [0002] As we all know, the chemistry laboratory is an important place to provide chemical experiment conditions and scientific inquiry. In the process of chemistry teaching in high school, various chemical experiments are carried out to help students better understand and master the subject of chemistry. course. Some commonly used instruments in the chemical laboratory of high school include measuring cylinder, beaker, reagent bottle, test tube or rubber tip dropper, etc. When conducting high school chemical experiments, it is necessary to quantitatively prepare various chemical reagents. At present, when chemical reagents are allocated, mostly the reagents are first poured into the graduated cylinder, after the volume of the che...
