Sonicator

( www.abnova.com ) - Sonicator agitates particles in a sample by applying sound (usually ultrasound) energy. In the laboratory, it is usually applied using an ultrasonic bath or an ultrasonic probe. More videos at Abnova ( www.abnova.com ).

@twink06 Sonication has the capacity to break intermolecular interactions - it can aid in disrupting cell membranes allowing release of cytoplasmic constituents... vortexing is just mixing, and in cases where you want to avoid frothing of a sample, sonication has obvious benefits over vortexing as it doesn't introduce air into the sample; in fact, it also aids in removing gasses from aqueous samples.
