Experimental device capable of quickly comparing chemical experiments

Abstract

The invention provides an experimental device capable of quickly comparing chemical experiments. The experimental device comprises a test tube stand, an anti-corrosion under frame, a white board, a base and an isolation board, wherein the test tube stand is fixedly arranged in the middle position of the left side of the isolation board; the anti-corrosion under frame is embedded and arranged at the top part of the left side of the base; the anti-corrosion under frame is connected with the bottom part of the left side of the isolation board by using a wood tenon structure, and a connecting partis covered and protected by carpentry paint; the white board is fixedly arranged at the top part of the right side of the base; the white board clings to the right side end of the isolation board; the end surface of the back part of the white board and the end surface of the back part of the base are located in the same horizontal plane. Through the arrangement of the anti-corrosion under frame and an information sign, an experimental sample can be marked by an experimenter by utilizing the information sign, and convenience is provided for the experimenter to identity and record, and meanwhile, the anti-corrosion under frame is capable of preventing a content in a test tube from corroding the surface of a table when the experimenter is in misoperation; the experimental device is suitablefor production and use in the technical field of teaching aids, and has a good development prospect.

Description

technical field [0001] The invention relates to the technical field of teaching tools, in particular to an experimental device. Background technique [0002] When conducting traditional chemical experiments, a large part of chemical experiments need to compare different experimental samples. The comparison content usually includes color, speed, gas output and material type, etc. In order to compare, it usually needs Prepare multiple sets of experiments. At the same time, most chemical experiments are dangerous. In traditional chemical experiments, students operate the experimental equipment manually, and its safety cannot be guaranteed. Students often accidentally break the test tube beaker or even scratch themselves. . [0003] The existing chemical experiment devices usually have weak safety protection, and the content comparison is not convenient and fast enough, which brings great inconvenience to the experimenters. Contents of the invention [0004] The purpose of t...
