Laboratory Ultrasonic Mixer

Principle of Laboratory Ultrasonic Mixer

The experimental ultrasonic mixer uses ultrasonic waves to crush insoluble solids (or liquids). The physical mechanism is generally considered to be the ultrasonic cavitation effect. Ultrasonic cavitation effect means that under the action of strong ultrasonic waves, a large number of bubbles will be generated in the liquid. The small bubbles will gradually grow and increase with the ultrasonic vibration, and then suddenly burst and split. The split bubbles will continue to grow and burst. . When these small bubbles collapse rapidly, high temperature and high pressure are generated in the bubble, and because the liquid around the bubble rushes into the bubble at high speed, a strong local shock wave is generated in the liquid near the bubble, which also forms local high temperature and high pressure, thus producing Ultrasonic crushing and emulsification.

Characteristics of Laboratory Ultrasonic Mixer

• Efficient and uniform: The strong vibration energy of ultrasound can quickly and uniformly mix various materials, greatly reducing the mixing time.
• Easy to operate: The device has a compact structure and is easy to operate. Simply place the container into the device and set the appropriate parameters.
• Widely applicable: It can be used for mixing various types of liquid and solid materials, and can even be safely used for certain biological samples and chemical reagents.
• Non-polluting: Due to its non-contact mixing, it effectively avoids material contamination and cross-contamination.
• Good repeatability: Due to the high uniformity of ultrasonic mixing, the results of each experiment have good repeatability.

Comparison between Laboratory Ultrasonic Mixer and mechanical mixing dispersion methods

The ultrasonic stirring equipment consists of two parts: an ultrasonic stirring system and an ultrasonic driving system (ultrasonic generator). The ultrasonic stirrer mainly includes a transducer, an ultrasonic amplitude lever, and an ultrasonic tool head for generating ultrasonic vibration and emitting this vibration energy into the liquid

1. Mechanical stirring dispersion
Mainly relying on mechanical energy such as external shear or impact force, nanoparticles are fully dispersed in the medium. By applying mechanical force to the dispersion system, changes in the physical and chemical properties of the substances in the system, as well as a series of accompanying chemical reactions, are achieved to achieve dispersion. However, mainly relying on mechanical energy such as external shear or impact force, nanoparticles are fully dispersed in the medium
2. Ultrasonic dispersion
By utilizing local high temperatures, strong shock waves, and micro jets generated by ultrasonic cavitation, the interaction between nanoparticles can be significantly weakened, effectively preventing their aggregation and allowing them to be fully dispersed. Ultrasound plays an important role in the synthesis of compounds, degradation of polymers, and dispersion of particulate matter
