Many laboratory solutions in the laboratory require temperature control in ultrasound during the ultrasound process by an ice bath (or water bath) step. The process needs to fix the centrifuge tube (or other containers) filled with the sample to be sonicated by using a corresponding fixing device, and keeps the liquid in the containers to be always soaked in the ice bath in the sonicating process, so that the temperature in the sonicating process is kept constant, the influence of the heat generated by the ultrasound is reduced, and the uniformity and consistency of the ultrasound effect in the sonicated solution are ensured.

However, in most laboratories today, the present inventors have found that the following problems exist: the whole structure of the existing centrifugal fixing frame is fixed, and when the centrifugal tubes (or other containers) with different sizes are fixed, different supports are required to be used for clamping, so that the mobility of the supports is small. In addition, the liquid level of the sample subjected to ultrasonic treatment cannot be kept at a fixed height in the ice bath (or water bath) ultrasonic process, and the height is difficult to be accurately adjusted in a visual manner by the traditional fixing device, so that the ice bath effect is greatly influenced, the uniformity of ultrasonic crushing is reduced, and serious consequences such as degradation of temperature-sensitive experimental materials in the sample are extremely easily caused.

Accordingly, in view of the above, the fixing structure of the centrifuge tube (or other container) in the existing ice bath (or water bath) and the defects and limitations thereof are researched and technically improved, and the novel universal fixing support for visually adjusting the height is provided, which is used for fixing the centrifuge tube (or other container) in the process of ultrasonic crushing in the ice bath (or water bath) so as to achieve the advantages of being more flexible and easy to use, being compatible with centrifuge tubes (or other containers such as beakers) with different specifications, being easy to perform visual height adjustment, and having the advantages of flexibility, convenience and strong practicability. The device can improve the uniformity of ultrasonic crushing, avoid degradation of samples caused by uneven temperature, and greatly improve the efficiency of ultrasonic experiments.
