Abstract
A flow disrupter in a tube chamber of a tube assembly for homogenizing sample materials includes a flow-disrupting body that extends generally transversely into the tube chamber and divides the tube chamber into two sub-chambers. The flow-disrupting body includes at least one narrowed flow passageway through which the sample flows back and forth in both axially reciprocating directions as the tube assembly is vigorously shaken at high speeds faster and more reliably than what can be accomplished by hand shaking. And the flow-disrupting body includes at least two flow-interrupting surfaces facing generally in opposite axial directions and against which the sample impacts in each respective axially reciprocating direction as the tube assembly is vigorously shaken. In this way, the vigorous high-speed shaking of the tube assembly including the flow disrupter results in significant particle-size reduction of the sample by mechanical shear, fluid shear, cavitation, and/or pressure differentials.
