20Khz non-invasive Ultrasonic Sonication Transducer for vibrating test tube

Parameter

Description

The ultrasonic mixing device based on the transducer principle is a common liquid processing device, which uses the mechanical oscillation and cavitation of high-frequency ultrasonic waves in the liquid to perform ultrasonic mixing and ultrasonic stirring on solutions, emulsions, suspensions, etc. , ultrasonic dispersion, ultrasonic crushing and other effects.

Common ultrasonic cell disruptors, ultrasonic sewage treatment, ultrasonic mixing and crushing devices are all devices based on this principle. However, the power of the above-mentioned general ultrasonic mixing devices is relatively high, and the ultrasonic emitting head needs to be in contact with liquid. In some fields of in vitro diagnostics, it is usually necessary to perform pretreatments such as mixing and crushing of biological samples, and most of the samples are only small doses of milliliters or even microliters. Also, if the processing device comes into contact with the sample, it can contaminate the sample. Therefore, traditional ultrasonic mixing devices are not suitable for these in vitro diagnostic fields

At present, non-contact treatment methods mainly include: centrifugal separation method, ultrasonic water bath method, low-frequency mechanical vibration method (such as rocking method), magnetic stirring method, etc., among which ultrasonic water bath method is a more commonly used method. The ultrasonic water bath method is to put the test tube in the water tank, and the shock wave generated by the ultrasonic vibration in the water is transmitted to the outer wall of the test tube, and then into the liquid in the test tube; because the shock wave cannot be directly transmitted to the test tube, it is inevitable that the shock wave will be transmitted to the test tube. Certain attenuation, that is, the ultrasonic transmission effect is not good, which affects the sample processing efficiency; in addition, a water tank is required, which makes the operation inconvenient.
