Description

Technical Field

[0001] The utility model relates to the technical field of test tube racks, in particular to a test tube rack which is convenient for classified placement. Background Art

[0002] In the laboratory, there are many kinds of practical instruments. Test tubes are the most commonly used experimental instruments. They are used as reaction containers for small amounts of reagents and to store some experimental liquids to be tested. Test tube racks are a kind of racks for placing test tubes. They are usually made of plastic, metal or glass. Test tube racks have various sizes and shapes and can be selected according to needs. Test tube racks can usually be divided into ordinary test tube racks, round test tube racks and square test tube racks.

[0003] The principle of existing test tube racks is generally to select a suitable test tube rack by determining the size and number of test tubes, ensure that the test tube rack has enough slots to accommodate the test tubes, before using the test tube rack, make sure that the test tubes have been cleaned and dried, and can be marked, insert the test tubes vertically into the slots of the test tube rack, ensure that the test tubes are stably placed in the slots to avoid loosening or slipping, and store different types of test tubes separately in different test tube racks so that the required test tubes can be found during the experiment.

[0004] When a test tube rack that is easy to classify and place is used, the test tubes generally need to be placed on the test tube rack to prevent the test tubes from falling and being damaged. However, there are many test tubes that need to be placed on the test tube rack, and a group of test tubes in use cannot be separated and placed according to needs, which makes it inconvenient to take and place the test tubes. Moreover, when some experiments require more data, a large number of test tubes need to be used. However, the existing test tube racks are usually set as an integral type and cannot adjust the number of test tubes to be stored. Therefore, the number of test tube racks needs to be increased to meet the experimental needs. When the number of test tube racks is increased, the space occupied by the test tube racks will increase. Too many test tube racks will make the laboratory space crowded, which not only affects the normal work of the experimenters, but also may make it impossible to place the experimental equipment smoothly and may cause safety hazards, thereby reducing the use effect of the test tube rack and failing to meet people's needs.
