optimization of cell disruption with bead mill

Bead MillingMethod OfCell Disruption.Jun 19, 2019. There are many methods ofcell disruptionamong which the mechanical methods ofbead milland high pressure homogenizer are used not only in laboratory but also in industry. Other methods are still in the laboratory, and industrial applications are still being explored.

    Thecell suspensionis pumped continuously through the narrow gap between rotor and stator that is partially filled withdisruption beads.The volume of thedisruptionchamber is only 25% of thedisruptionvolume required by a conventionalbead millwith the same throughput. Another advantage of the CoBall-Mill is the strong cooling capacity, which is very useful for the processing of bioactive products.
