Abstract

A device for lysing components (e.g., cells, spores, or microorganisms) of a fluid sample comprises a cartridge having a lysing chamber for receiving the sample and having at least one solid phase in the lysing chamber for capturing the sample components to be lysed. An ultrasonic transducer is coupled to a wall of the lysing chamber to transfer ultrasonic energy to the captured sample components.
