[0002] Ultrasonic technology is a common pretreatment operation in sample analysis and detection, and the sample is usually contained in an open container, including a centrifugal tube. In the prior art, a plurality of centrifugal tubes containing samples are generally placed on a centrifugal tube rack, and then immersed in water together with the centrifugal tube rack for ultrasonic pretreatment. However, when the centrifugal tube itself is light in weight, and the sample in the centrifugal tube is also light in weight, the centrifugal tube is prone to float and tip over under the action of buoyancy. At the same time, the temperature rises during the ultrasonic pretreatment process, which causes the air pressure in the centrifugal tube to rise accordingly, which can cause the cap of the centrifugal tube to separate from the centrifugal tube at the opening, water to enter the centrifugal tube and contaminate the sample, and affect the normal operation of the ultrasonic pretreatment. In addition, in some ultrasonic pretreatment processes, the centrifugal tube is not sealed, which can cause foreign matter to fall into the centrifugal tube and contaminate the sample, also affecting the normal operation of the ultrasonic pretreatment.
