Description

Technical Field

[0001] The utility model belongs to the technical field of test tube racks, and particularly relates to a test tube rack. Background Art

[0002] A test tube rack is a device for supporting and placing test tubes. It is usually composed of a base and a rack body. The base is used to fix and support the rack body, and multiple test tube fixing holes are provided on the rack body. During use, the test tubes are placed in the test tube fixing holes, so that the rack body supports and limits the test tubes.
