Abstract

This utility model discloses a laboratory ultrasound auxiliary device, relating to the field of ultrasound experimental technology, including a base plate, side plates, and a cover plate. The base plate and cover plate are laid flat, with the cover plate located above the base plate. The upright side plates are fixed to the top of the base plate, and the cover plate and side plates are detachably connected. A centrifuge tube rack holding various centrifuge tubes is placed on the base plate, confined between the base plate and the cover plate. This utility model provides a cover plate that is detachably installed above the base plate and is connected to the side plates. The base plate and cover plate achieve coarse positioning of the centrifuge tube rack and centrifuge tubes in the direction of buoyancy, preventing the centrifuge tubes from tilting upwards due to buoyancy during sample pre-ultrasound treatment, or preventing the centrifuge tube caps from detaching from the centrifuge tubes due to increased internal pressure. In pre-ultrasound treatment where some centrifuge tubes are not sealed, the cover plate can also block the opening of the centrifuge tubes, preventing foreign objects from falling into the centrifuge tubes and contaminating the sample, thus ensuring the normal operation of the pre-ultrasound treatment.
