Description

[0002] The friability wheel is an important component used in analytical instruments and is mainly used to detect the friability of materials. The design and working principle of this wheel is based on the reaction and behavior of materials when subjected to external forces. When a material is subjected to an external force, if it breaks easily, it can be considered to have a high friability. On the contrary, if the material can resist the external force to a certain extent, its friability is low.

[0003] In the prior art, after the test is completed, the friability wheel needs to be pinched out of the debris one by one with tweezers, which is very inconvenient to use and reduces the detection accuracy. In addition, the friability wheel of the analytical instrument usually needs to be tilted for detection when in use, and this step often requires the entire instrument to be tilted to form a certain angle with the horizontal plane. Currently, the tilt angle is mostly adjusted by placing a foot on one side of the bottom, which is inconvenient to adjust. Utility Model Content
