    Abstract: A device for use with an ultrasonic transducer to lyse components of a fluid sample comprises a cartridge having a lysing chamber, an inlet port in fluid communication with the lysing chamber, and an outlet port for exit of the sample from the lysing chamber. The inlet and outlet ports are positioned to permit flow of the sample through the lysing chamber, and the chamber contains at least one solid phase for capturing the sample components to be lysed as the sample flows through the chamber.
