What does sonication and sonichemistry look like in action? In this liquid, it looks like a color change. 🧪✨
The Hielscher UP400St sends high-power ultrasound through the sample, creating microscopic bubbles that collapse almost as quickly as they form. This process, called cavitation, produces powerful local mixing and reactive conditions throughout the liquid. 🫧
Researchers use cavitation to help reactions proceed, move substances between phases, disperse particles, and break apart agglomerates. Its applications range from synthesis and oxidation to extraction, emulsification, and catalyst activation.
The changing color allow to see the effect of ultrasonic processing as it happens.

Electrochemistry - Intensified by Sonication!

In this clip, the Hielscher sonicator UP400St runs its ultrasonic probe as an electrode in a sono-electrochemical setup. One device supplies the electrical function and the acoustic field at the same time.

That combination changes what happens at the surface. Ultrasonic cavitation collapses near the electrode and sends microjets into the interface, while acoustic streaming renews the electrolyte layer fast.
Mass transfer improves, diffusion layers shrink, and the surface stays clean - deposits and reaction products get stripped before they can passivate the electrode.
The result is higher current density, better yields, and more reproducible reactions than a silent electrode typically gives.
Hielscher builds sonicators for use as electrodes in sono-electrochemical process setups, with probe materials and geometries suited to electrochemical environments.
Run it as an academic research rig or as a production process.

Sterile Sonication in Closed Vial with the VialTweeter-spec
This specialized Hielscher VialTweeter delivers 90 watts of ultrasound uniformly from all sides - powerful sonication with 12 µm amplitude. That means sonication intensity comparable to a direct sonotrode and approximately 300× higher than an ultrasonic bath.
Watch it rapidly disperse black graphite flakes, then transform vegetable oil and water into a translucent emulsion. ⚡
Closed-vial sonication allows for sterile sample preparation minimizing cross-contamination and aerosol formation - and there’s no sonotrode to clean between cycles.

Powerful sonication - without opening the vial. 🔊🧪
This specialized Hielscher VialTweeter setup delivers high-intensity ultrasonic energy into closed sample vials, enabling uniform sonication from all sides without direct probe contact.
That means samples can be processed safely, reproducibly, and efficiently while remaining sealed. No probe immersion. No cross-contamination. No cleaning of sonotrodes between individual runs. ✨
The VialTweeter is ideal for laboratories that need consistent ultrasonic treatment across multiple small-volume samples - from sample preparation and nanodispersion to emulsification, sonochemistry, materials research, and analytical workflows.
Closed-vial sonication helps streamline routine lab processes while protecting sensitive samples and improving reproducibility. ⚗️🔬

Watch chemistry change before your eyes. 🧪🔊✨
This video shows an ultrasonic cavitation-induced color change in liquid - a visible effect of the intense physical and chemical forces generated by high-power ultrasound.
When the Hielscher UP400St sonicator introduces ultrasonic energy into the liquid, millions of microscopic cavitation bubbles form, grow, and collapse within fractions of a second. This collapse creates extreme local conditions, including high shear forces, intense micro-mixing, and highly reactive zones that can trigger or accelerate chemical transformations. ⚡🫧
In sonochemistry, these cavitation effects are used to intensify reactions, improve mass transfer, disperse particles, break down agglomerates, and support processes such as synthesis, oxidation, extraction, emulsification, and catalyst activation.
The visible color change makes ultrasonic chemistry tangible: sound energy becomes chemical action. 🌈

Processing with no touch. No heat. No chemicals. Just sound. 🔊✨
Hielscher’s stepped plate resonator uses high-intensity airborne ultrasound to create a focused acoustic field for contactless material processing.
That means sensitive products can be dried, cleaned, streamed, or defoamed without mechanical abrasion or thermal stress. From food and coatings to electronics, optics, pharmaceuticals, aerospace components, and advanced materials - sound waves open new possibilities for non-invasive processing. ⚙️🧪
The stepped resonator geometry concentrates ultrasonic energy where it is needed most, supporting scalable and efficient operation for demanding industrial and research applications.
Research on ultrasonic-assisted atmospheric freeze drying shows why this matters: airborne ultrasound can increase turbulence at the solid-gas interface, reduce boundary layer thickness, and enhance diffusion - helping to accelerate drying while supporting low-temperature processing. ❄️💨
