A temperature control method for a laboratory ultrasonic biological treatment system

Abstract

A temperature control method for a laboratory ultrasonic biological treatment system, the system's treatment liquid temperature control system is composed of a temperature comparison link, a temperature control link, an amplification link, a refrigerator switching execution link, and a temperature feedback link. The set given processing liquid temperature and the processing liquid temperature feedback variable are compared in the comparison link stored in the controller chip to generate a deviation temperature; after calculation and processing in the temperature control link stored in the controller chip, the deviation temperature is converted into refrigeration control logic Signal; in the amplification link, the refrigeration control logic signal is amplified and converted into the refrigerator switching execution driving voltage; the refrigerator switching execution driving voltage is executed and converted by the refrigerator switching execution link, and becomes the temperature of the treatment liquid in the treatment tank; After calculation and processing by the temperature feedback link, the temperature of the treatment liquid in the treatment tank is converted into a feedback variable of the treatment liquid temperature and introduced into the temperature comparison link.

Description

technical field [0001] The invention relates to a laboratory ultrasonic biological treatment device, process and method. 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 different. This has caus...

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.
