Ultrasonic topic: "Ultrasonic Nanomaterial Processing"
High-performance sonication is a well-established technique for particle size reduction in nano-sized dispersions and emulsions. Besides the fine-size distribution of particles, ultrasonic processors are used to synthesise nano-structured materials such as nanodiamonds or to precipitate nanoparticles (e.g. magnetite (Fe3O4)).
Hielscher’s ultrasonic processors are available from lab to industrial size and can be used for batch and continuous inline sonication. Learn how sonication can improve your nano-material processing!
