Sonication in laboratory ultrasonic cleaners is a widely accepted process for the dispersion or separation of nanoparticles in liquids – that is breaking up nanomaterial agglomerates.   It is an effective alternative to other dispersion methods such as rotor-stator homogenizers, piston homogenizers and wet milling.  A number of factors should be considered when selecting ultrasonic equipment to break up agglomerates whether you use a solvent-based or aqueous suspension.

As an introduction you must keep in mind that the optimum performance settings of the ultrasonic equipment may vary depending on the agglomerates being dispersed.   In other words if you are working with a variety of nanoparticles you should investigate equipment with adjustable operating parameters.

Here we provide some guidelines on ultrasonic equipment selection for nanoparticle dispersion.

Ultrasonic power: 

In this case power refers to the ultrasonic power input into the bath.  In this post we use the 3-quart capacity dual frequency … Read the rest
