Description

Technical Field

[0001] The utility model relates to the technical field of test tube clamping, in particular to a test tube clamper. Background Art

[0002] A test tube is a common piece of laboratory equipment, typically made of glass or plastic, in the form of a long tube with a closed bottom and an open top. They are primarily used to contain, mix, heat, or cool liquids and chemical reagents for various experiments. In biological research, they can be used to culture microorganisms, cells, or tissue samples. They can be used to observe chemical reactions, allowing experimenters to record and analyze the results. In medicine, test tubes are often used to collect and transport blood or other biological samples. A test tube holder is a laboratory tool designed to secure and hold test tubes for heating, stirring, and other experimental operations.

[0003] Traditional clamps are generally designed with a fixed clamping force and cannot be adjusted according to the diameter and material of the test tube, which may cause damage to the test tube or loose clamping. They cannot adapt to different types of test tubes and have a relatively limited range of use. Users need a variety of clamps to meet different experimental needs. Many traditional clamps require disassembly or replacement of components when adjusting the clamping force. The operation process is complicated and time-consuming, which is not convenient.
