Hangzhou dowell ultrasonic specializes in liquid processing by high-power ultrasound. We offer high-intensity laboratory,bench and industrial-scale ultrasonic processors used as ultrasonic homogenizers, sonicators, ultrasonic mixers, sonochemical reactors and ultrasonic wet milling processors in a wide variety of industries. Our equipment can be used for the production of nanoparticles, such as nanoemulsions, nanocrystals, liposomes and wax emulsions, as well as for wastewater purification, degassing, extraction of plant oil, production of biofuels, crude oil desulphurization, cell disruption, polymer and epoxy processing, adhesive thinning, and many other processes. We serve pharmaceutical, cosmetic, water, food, ink, paint, coating, wood treatment, metalworking, nanocomposite, pesticide, fuel, wood product and many other industries.

High ultrasonic amplitudes able to generate intense acoustic cavitation are required for most processes. Unlike conventional ultrasonic devices, Barbell horn-based ultrasonic systems make it possible to produce extremely high ultrasonic amplitudes at any scale, from laboratory to industrial, guaranteeing reproducible results after scale-up. Our experienced consultants will be glad to help optimize your process and implement it in your production environment.
