Description

technical field [0001] The invention relates to a laboratory ultrasonic biological treatment process, method, system and circuit thereof. Background technique [0002] The laboratory equipment, process and method of ultrasonic biological treatment are still in the mode of single-frequency treatment, group control and inductive effect. The current laboratory method of ultrasonic biological treatment is: by setting or selecting a certain working frequency of the ultrasonic generating equipment in advance, and then using the ultrasonic frequency of this frequency to act on the treatment object. However, the processing rate of ultrasonic waves on objects is highly correlated with ultrasonic frequency, and the processing efficiency varies greatly with different ultrasonic frequencies; moreover, the type of biological cells to be processed is highly related to ultrasonic frequency, and different biological cells are sensitive to different frequency ultrasonic waves. very differen...

Problems solved by technology

In essence, such a method cannot guarantee that the working ultrasonic frequency is the optimal frequency for the object, nor can it perform precise and fine frequency adjustments for different objects, and the accumulated experience is not the best process; in addition, the The method not only consumes a lot of manpower, financial resources and material resources in the initial stage, but also often requires observation, adjustment and maintenance during the use period.
