PROBLEM TO BE SOLVED: To provide an improved apparatus and method for disrupting cells or viruses to release nucleic acids therefrom. SOLUTION: The apparatus 10 for disrupting cells or viruses includes a container 18 having a chamber for holding the cells or viruses. The chamber is defined by at least one wall having an external surface to which is coupled a transducer device 38. The transducer device 38 vibrates at an operating frequency and amplitude sufficient to generate pressure waves or pressure pulses in the chamber. The transducer device 38 is coupled to the wall with a preload force sufficient to create a stress within the wall. COPYRIGHT: (C)2010,JPO&INPIT |
