Test-tube rack

Abstract

The invention belongs to the technical field of biochemical experiment auxiliary appliances and provides a test-tube rack in order to solve the problems that an existing test-tube rack is small in compatible range and complicated in structure, cannot position test tubes accurately and cannot clamp the test tubes stably and the like. The test-tube rack comprises a main body, wherein inserting holesallowing insertion of the test tubes are formed in the main body; the test-tube rack further comprises elastic pieces and adapters, the elastic pieces are arranged in the inserting holes and can supply elastic pressure to the test tubes, the adapters are inserted in the inserting holes and provided with through holes allowing insertion of the test tubes, each adapter is further provided with a notch yielding to the corresponding elastic piece, and the elastic piece can penetrate through the notch to supply elastic pressure to the corresponding test tube. With combination of the adapters and the elastic pieces, the test-tube rack can load and position the test tubes stably and accurately; besides, the test-tube rack requires a few parts and is simple in structure, the adapters can be processed into various sizes, various test tubes can be compatible by selecting the adapters with proper sizes, the operation is easy, flexibility is quite high, and the manufacturing cost of the test-tuberack is low.

Description

technical field [0001] The invention relates to a biochemical experiment auxiliary equipment, in particular to a test tube rack. Background technique [0002] Commonly used test tube racks are provided with jacks for test tube insertion, and the size of the jacks is fixed. Different jacks can only be inserted into test tubes of corresponding sizes, and their compatibility is very low. Although a test tube rack can be provided with multiple jacks of different sizes, its compatible range is still very limited. In order to facilitate the insertion and removal of the test tube, the size of the hole is generally slightly larger than the diameter of the test tube, and the inner wall of the hole cannot completely hold the test tube tightly, which means that the test tube rack cannot be subjected to violent vibrations, otherwise the test tube may fall out of the hole. Further, since the insertion holes cannot be fully matched with the test tubes, the test tubes cannot be fixed on t...
