When conducting geological experiments, test tubes are usually placed on test tube racks.

[0003] The test tubes placed on the existing test tube racks for geological experiment tests cannot be tilted, which makes it inconvenient to observe the reaction conditions in the test tubes during geological experiments. Moreover, after the test tubes are cleaned, they are often required to be placed in the test tube rack with their mouths facing downwards for draining and drying. Since the test tube mouths are buckled downwards at the bottom of the test tube rack, air inside the test tubes is not circulated, which also causes inconvenience for drying the test tubes. Therefore, the utility model provides a test tube rack for geological experiment tests, which is used to allow the test tubes to rotate on the test tube rack. Utility Model Content
