Description

Technical Field

[0001] The utility model belongs to the technical field of test tube brackets, and specifically relates to a test tube fixing device. Background Art

[0002] A test tube fixture refers to a device used to fix test tubes. With the development of society and the improvement of safety awareness, test tube fixtures can improve the safety of experiments. Fixing test tubes can reduce the risk of test tube breakage, splashing or accidental injury during experiments, and ensure the safety of experimenters, especially when dealing with toxic, corrosive or volatile reagents. The demand for test tube fixtures is particularly important in the field of scientific research. In experiments in the fields of chemistry, biology, medicine, etc., a variety of liquids need to be mixed, reacted or cultured, and these operations usually require the use of test tubes. The test tube fixture can fix the test tube in a specific position to ensure that the test tube will not tilt or move during the experiment, ensure the accuracy and repeatability of the experimental data, and promote the progress of scientific research.

[0003] Existing test tube racks are usually designed to be large and are mainly used for long-term use in laboratories, which does cause inconvenience in carrying and transportation to a certain extent. Most test tube racks are made of materials such as metal or plastic and have relatively complex structures, so they are large in size, resulting in a heavy overall weight, which is not convenient to carry and transport. Due to their large size, test tube racks are not suitable for use in mobile scenarios, such as field experiments, exhibitions or teaching classrooms, which limits the scope of use and convenience of test tube racks. Large test tube racks can easily cause accidental injuries or damage other items during carrying and transportation, especially in narrow spaces or crowded environments, where there may be a risk of collision or tilting.

[0004] In summary, the existing test tube rack has the problem of being large in size and inconvenient to carry. Utility Model Content
