![]() “In the food and pharma industry, ultrasonic extraction is a hot topic, whilst the paint and coating industry is mostly interested in the nano-size milling and dispersing.” She adds, “Especially demanding tasks, such as those in nanotechnology or biology, often cannot be fulfilled with a traditional mixing device and require a powerful homogenizer that can be precisely controlled.” “The trending applications vary from industry to industry,” says Kathrin Hielscher, marketing manager at Hielscher Ultrasonics in Teltow, Germany. The features that matter the most in an ultrasonic liquid processor depend on the user’s needs. As Lustig explains, “We are able to focus highintensity ultrasonic energy to a wide area and effectively shear 20 sample tubes at one time.” He adds, “This is a high throughput solution for labs that need to process many samples per day.” Optimizing the options Plus, it can simultaneously prepare multiple samples.

Gupta, associate dean for research and an engineering professor, says, “I use the processor for reactions that contain both solids and liquids.” He adds, “The intense mixing that comes out of physical movement and cavitation greatly increases the reaction rate.” Smashing the small ![]() This seemingly violent process can be controlled to process samples of various sorts.Īt Virginia Commonwealth University in Richmond, Ram B. ![]() This process creates cavities-bubbles-in the sample, and then cavitation-the bubbles imploding-shears the sample. Instead of chopping up samples with mechanical blades, more or less like a food processor, an ultrasonic liquid processor uses a piezoelectric transducer to convert electrical energy to mechanical vibrations that a probe amplifies into pressure waves in the sample.
