  • Patent number: 11774329
    Abstract: An active/resilient grinding media inside a tube containing a sample is oscillated rapidly by a homogenizer so that the active media is driven in a first direction until it impacts a first end of the tube, which causes it to deform and store an energy charge as it decelerates and stops, and it then accelerates rapidly in the second opposite direction under the discharging force of the stored energy toward the opposite second end of the tube. This cycle of the active media decelerating/charging and then discharging/accelerating is repeated throughout the entire oscillatory processing of the sample. The result is much higher velocities of the active media and therefore much greater impact forces when the sample and active media collide, producing increased efficiency in disruption and size-reduction of the sample particles.
