Abstract
The present invention relates generally to a method and apparatus for applying wave energy of an ultrasonic frequency to agitate particles in a sample. The agitated sample is then delivered via a syringe or a resonating syringe plunger attachment of an applicator. More particularly, the present invention relates to establishing and maintaining a liquid suspension delivery system that prevents dispersed particles from precipitating out of suspension while the sample is delivered through to various applicators, such as resonating syringe plungers.
