  • Method and apparatus for comminution of biological specimens
    Patent number: 7467754
    Abstract: An apparatus for comminuting biological specimens includes a receiving component provided with a drive source, a sample retainer configured for retaining at least one biological specimen and for engagement in the receiving component, and a single use comminution mechanism in operational relationship with the sample retainer. The drive source is configured for driving the comminution mechanism. A collector is associated with the receiving component for receiving comminuted product generated by the comminution mechanism. A method for comminuting biological specimens is provided so that, upon comminution, the specimen is readily subject to rapid extraction and detection of drugs and their metabolites, compounds, chemicals, pesticides, steroids, growth enhancers, contaminants or other pharmacologic agents which may reside in the specimen.
