Description

Technical Field

[0001] The utility model relates to the technical field related to ultrasonic cleaning auxiliary tools, in particular to an ultrasonic cleaning auxiliary device for laboratories. Background Art

[0002] Ultrasonic cleaner is a device used to remove pollutants. It converts high-power ultrasonic energy into mechanical vibrations through a transducer to clean objects. It is widely used in laboratories. When ultrasonically cleaning small beakers, volumetric flasks, measuring cups and other small containers, the container is directly placed in the cleaning tank and the ultrasonic cleaner is started. Since the bottom of the tank is not completely horizontal, the container will move around and cannot remain stable. The user needs to hold it by hand, which reduces the cleaning efficiency and increases the burden on people. Utility Model Content
