Chemical test chamber for students

Abstract

The invention provides a chemical test chamber for students. The chemical test chamber comprises a chamber cover, a chamber bottom, a drawer type test frame and a small drawer, wherein a plurality of positioning buckles are mounted on the front inner surface of the chamber cover; the inner part of the chamber bottom adopts a three-step structure, a hollow cavity is formed in a place under the front of the three-step structure, the small drawer is accommodated in the hollow cavity, a hollow cavity is also formed in a place under the back of the three-step structure, and the drawer type test frame is accommodated; a grid section is arranged at the left part of the drawer type test frame, another grid section is arranged at the right part of the drawer type test frame, a tripod is fixed on the grid sections, an alcohol lamp is placed under the grid sections, and the whole drawer type test frame can be pulled out and can also be pushed in; a grid section 4 is arranged on a first step of the box bottom, a grid section 5 is arranged on a second step, a test tube frame which can be taken out is placed on a third step, and a grid section 6 and a plurality of thin columns are arranged on the test tube frame.

Description

technical field [0001] The invention relates to a chemical test box for students in particular. Background technique [0002] General chemical tests are carried out on indoor test benches, and most of the instruments and medicines required for the tests are placed on the test benches or on the instrument medicine racks, which cannot be carried around at will. At present, our country’s education funds are limited. Some schools, especially rural middle schools, agricultural middle schools, various vocational schools, and broadcasting schools, cannot set up chemical laboratories for a while. Studied by rote, divorced from reality, and extremely poor in practical ability in experiments, these are problems that urgently need to be solved in the chemistry teaching of the above-mentioned types of schools. Contents of the invention [0003] The object of the present invention is to address the deficiencies of the prior art and provide a chemical test box for students, which can w...

Problems solved by technology

[0002] General chemical tests are carried out on indoor test benches, and most of the instruments and medicines required for the tests are placed on the test benches or instrument drug racks, which cannot be carried around at will.

At present, our country’s education funds are limited. Some schools, especially rural middle schools, agricultural middle schools, various vocational schools, and broadcasting schools, cannot set up chemical laboratories for a while. Studied by rote, divorced from reality, and extremely poor hands-on ability in experiments, these are the urgent problems that exist in the chemistry teaching of the above-mentioned types of schools
