09 14 32 Cell disruption using bead mill Bead mill equipment consists of a tubular vessel made of metal or thick glass within which the cell suspension is placed along with small metal or glass beads The tubular vessel is then rotated about its axis and as a result of this the beads start rolling away from the direction of the vessel rotation At higher rotation speeds some the beads move up along The DYNO MILL KD disc mills are available with grinding chamber volumes from 015 to 600 litres and are suitable for practically all types of grinding media The production mills can be operated with grinding bead diameters from 05 to 25 mm

OPTIMIZATION OF CELL DISRUPTION IN RAPHIDOCELIS Cell Disruption Grinding vs High Pressure Homogenization

The degree of cell disruption using bead mill increased with exposure time beads solution ratio and agitation speed while larger beads caused less disruption Findings revealed that bead milling with specific parameters optimized is one of the most effective methods of disintegrating the robust algal cellsThis method disrupts cells through the use of friction when the sample is placed between two hard surfaces the sliding action of one or both surfaces then causes a mechanical disruption Although it may be employed for frozen wet or dry samples grinding is most effective with solid sampl For example this method is highly recommended for plant tissue frozen in liquid nitrogen
