Description

Technical Field

[0001] The utility model relates to the technical field of test tube racks, in particular to an adjustable test tube rack. Background Art

[0002] An adjustable test tube rack is mainly used in laboratories to store and fix test tubes of various sizes for convenient experimental operations. This kind of rack usually has an adjustable structure that can be adjusted according to the size and shape of the test tubes to ensure that the test tubes can be stably fixed on the rack. The design and use of an adjustable test tube rack are to improve the efficiency and accuracy of laboratory work and ensure that the test tubes can remain stable and safe during the experiment.

[0003] In the prior art, the specifications of the test tube rack are fixed. Therefore, test tubes with larger apertures cannot be placed in the test tube rack, and some test tubes with smaller apertures cannot remain stable after being placed in it, which is very inconvenient during the experiment and operation. For this reason, it is necessary to purchase test tube racks of various aperture sizes, wasting materials. Moreover, the space occupied by the test tube rack is fixed. When the test tube rack is not in use, the occupied space of the test tube rack cannot be reduced, which is not convenient for the overall storage and movement of the test tube rack and saves the experimental table space.
