Abstract

The invention relates to the technical field of experimental equipment, and discloses a test tube placement rack for chemical experiments, which includes a base in which a storage battery is fixedly installed by bolts, and at least two independently working button switches electrically connected to the storage battery are fixedly installed on the base , the upper part of the base is fixed with a lower matching seat through bolts, and the upper part of the lower matching seat is installed with an upper matching seat through a bearing. The test tube placement rack designed by the present invention can effectively place, clean and dry the test tubes according to the use needs of the test tubes, thereby effectively facilitating the maintenance of the test tubes, reducing the physical consumption of the experimental operators, and can It is convenient for experiment operators to mark and select test tubes, saves experiment preparation time, improves experiment efficiency, and has high practical value.

Description

technical field [0001] The invention relates to the technical field of experimental equipment, in particular to a test tube placement rack for chemical experiments. Background technique [0002] A large number of test tubes are used in the chemical experiment process. Since the bottom of the test tubes is generally arc-shaped, it is difficult to place them upright. At this time, a test tube rack is required for placement. The traditional test tube rack can only temporarily place the test tubes, and it is inconvenient to find the test tubes when there are many test tubes, and it is also impossible to adjust the inclination angle of the test tubes, which brings great inconvenience to the chemical experiment. Contents of the invention [0003] The purpose of the present invention is to provide a chemical experiment test tube placement rack, which can make the use of chemical experiment test tubes more convenient, and in particular can adjust the inclination angle of the test ...
