Description
Technical Field
The utility model relates to the field of test tools, in particular to an adjustable test tube brush for a test.
Background
The test tube brush is an essential tool in the test process in the fields of biology, chemistry and the like. Whether the vessel is cleaned or not directly causes a difference in test data, and therefore, whether the test tube brush reaches every corner of the vessel and performs sufficient washing is particularly important. Most of the traditional test tube brushes are fixed in shape and cannot be adjusted according to the actual size and shape of a vessel, for example, when the vessel with a large mouth bottle such as a flask, a conical flask and a volumetric flask is cleaned, the vessel is difficult to stretch into due to the small diameter of the vessel when a larger test tube brush is selected; when a smaller test tube brush is selected, the test tube brush needs to be bent to achieve the purpose of washing each corner of a vessel, but the test tube brush is easy to damage, and the test tube brush cannot be used to wash dead corners, so that errors are caused to influence test data finally.
