Ultrasonicator Extractor
An Ultrasonicator Extractor uses probe-driven cavitation to speed solvent penetration, improve mass transfer, and keep extraction conditions consistent from run to run. Cavitation increases molecular movement and helps solvents reach extractable components faster than passive soaking or simple stirring alone.
QualiUltra™ offers two extractor families to match scale. QualiUltra™ Ext Series focuses on constant-temperature, benchtop extraction with detailed parameter control and traceable run curves. QualiUltra™ iExt Series is built for reactor-scale extraction with integrated stirring and cooling support for pilot batches.
Ultrasonicator Extractor Applications
- Botanical and natural product extraction
- Cavitation helps break plant tissue and improves solvent penetration, supporting extraction of active compounds from herbs, roots, and botanical solids. Temperature management can help protect heat-sensitive fractions during longer runs.
- Food and flavor processing R&D
- Ultrasonication supports extraction of flavors, pigments, and functional components from food-grade materials. Stirring helps keep solids suspended for better repeatability, while cooling support helps stabilize conditions when volatile compounds are present.
- Pharmaceutical and API intermediate research
- Ultrasonic-assisted extraction can speed solvent screening and method development. Controlled mixing supports consistent contact between solvent and solids, improving comparability across trials and supporting scale-up when the method is stable.
- Environmental and analytical sample preparation
- Ultrasonication supports extraction from soils, sediments, and particulate samples when organics or contaminants must be transferred into a solvent phase. Controllable power and consistent mixing improve prep repeatability, and cooling can help limit unwanted losses in longer cycles.
- Chemical processing and dispersion tasks
- Extractor systems can support slurry conditioning and dispersion steps tied to extraction or reaction workflows. Sonication reduces agglomerates while stirring maintains uniform distribution for more stable downstream separation behavior.

Theory and Method
How ultrasonic-assisted extraction works
Ultrasonic-assisted extraction relies on cavitation created by high-frequency vibration at the probe tip. Bubble formation and collapse generate localized shear and micro-jets that help disrupt solids and improve solvent contact. Stirring helps maintain uniform suspension in larger reactors, and cooling circulation can hold a tighter temperature window when compounds are heat-sensitive.
Typical workflow
A practical method loads solvent and material into the vessel or reactor, then stabilizes temperature where required. Set ultrasonic power and total time, plus pulse and interval timing when available, and monitor process temperature during the run. After extraction, separate solids via filtration or centrifugation and move the extract to downstream concentration or analysis steps.
