Ultrasonic topic: "Common applications of Ultrasonic Dispersers"
Ultrasonic dispersers are a reliable tool to disperse and deagglomerate micron- and nano-sized particles into uniform suspensions. Besides the common dispersing application, ultrasonic dispersers (also known as probe-type ultrasonicators) are used for manifold other processes in lab and industry.
The application fields of ultrasonic dispersers include liquid-solid mixtures, emulsification, extraction, disintegration and cell lysis, sonochemical reactions and many more.
Common applications of ultrasonic dispersers are the production of stable nano-emulsions and -suspensions; sample preparation e.g. soil samples to identify the presence of polycyclic aromatic hydrocarbons (PAHs); degassing and deaeration of samples; as well as the functionalization, activation and cleaning of particle surfaces (e.g. catalysts).

High Shear Mixing with Ultrasonics
High shear mixers apply high shear forces into liquids and slurries in order to provide the uniform dispersing, blending, and emulsification of two or more liquid-solid or liquid-liquid phases. Ultrasonication generates high shear forces via acoustic cavitation, which occurs when…

Ultrasonic Disintegration: Wetting, Dissolving, Dispersing
Ultrasonic integrators are widely used to wet, disperse or dissolve particles and powders into liquids. High-performance ultrasonicators create intense shear forces, which break and shatter aggregates, agglomerates and primary particles to microscopic or nano size. The uniform particle processing in…

Uniformly Dispersed CNTs by Ultrasonication
To exploit the exceptional functionalities of carbon nanotubes (CNTs), they must be homogeneously dispersed. Ultrasonic dispersers are the most common tool to distribute CNTs into aqueous and solvent-based suspensions. The ultrasonic dispersing technology creates sufficiently high shear energy to achieve…
