Hielscher Ultrasonics is known worldwide as top supplier of innovative ultrasonic devices, from lab homogenisers to industrial processing reactors. Typical applications include mixing and homogenising, grinding, dispersing and emulsifying, extraction, lysis and disintegration and sonochemistry.
Covering this wide range of applications, Hielscher’s ultrasonic devices are successfully used in almost every liquid processing industry: the dispersing and wet milling of particles in the ink, paint and coating sector; the processing of nanomaterials, i.e. to precipitate or functionalise nano-size particles; ultrasonic mixing for biodiesel production; sonochemistry and sonocatalysis to improve chemical reactions; lysis, fermentation and digestion for biological applications; homogenising, extracting and pasteurisation for food processing; or ultrasonic cleaning for endless materials, such as wire, cable, rods, tapes or tubes.
Ultrasonic devices made by Hielscher are used for lab samples, pilot-scale processing, process optimisation and full-scale production. This includes ultrasonic devices for the ultrasonication of any liquid volume, from several microlitres through hundreds of cubic metres per hour.

A research group has developed an ultrasound-assisted procedure using the UIP1000hd ultrasonicator from Hielscher to produce mesoporous metals.
A scavenger is a chemical substance that is added to a mixture in order to remove or deactivate impurities and marring by-products. ln many reactions, an excess of starting materials is used to drive a solution phase reaction to completion. The final mixture is composed of the desired product and one or more unwanted side products. This article from Hielscher explains the uses of scavengers, the power of ultrasonic mixing and the benefits of ultrasonic scavenging and discusses batch ...
Hielscher ultrasonic reactors are used in many industries to assist and improve the catalytic extraction processing (CEP) or so-called phase-transfer extraction (PTE). Catalytic extraction involves a heterogenous immiscible phase system, such as liquid-liquid or liquid-solid. Ultrasonic high-shear and cavitational forces improve the dissolving rates of solutes significantly, leading to a faster and more complete extraction.
The sonication of coal slurries contributes to various processes during the energy production from coal. Ultrasound promotes the catalytic hydrogenation during the liquefaction of coal. Furthermore, sonication can improve the surface area and extractability of coal. Undesired chemical side reactions during the de-ashing and desulphurisation can be avoided — accomplishing the process in much less time.
This video presents the DRS3500 ultrasonic wire and cable cleaning system from Hielscher Ultrasonics. The DRS3500 provides high-power ultrasound for the inline cleaning of continuous materials. Thanks to its high intense cavitational forces, it can remove dirt and residues such as soaps, lubricants and dust.
