  • Patent number: 11473049
    Abstract: Oscillating angularly rotating a container containing a material may cause the material to be separate. Denser or heavier material may unexpectedly tend to collected relatively close to the axis of rotation, while less dense or light material may tend to collect relatively away from the axis of rotation. Oscillation along an arcuate path provides high lysing efficiency. Alternatively, a micromotor may drive an impeller removably received in a container. Lysing may be implemented in batch mode, flow-through stop or semi-batch mode, or flow-through continuous mode. Lysing particulate material may exceed material to be lysed or lysed material and/or air may be essentially eliminated from a chamber to increase lysing efficiency.
    Type: Grant

  • Patent number: 9260475
    Abstract: Lysing may include agitating a specimen in a chamber along with a medium that includes a particulate lysing material that has an affinity for a biological material. Lysing material may include beads or other material which may be coated that facilitates binding. The medium may include a fluid with a high salt or low pH level. The biological material may be eluted by lowering a concentration of salt or increasing a pH level. Lysing materials with two or more different affinities may be employed. Heating may be used. Lysing may be performed in a flow through apparatus.
