17. Cell disruption 17 Mechanical cell disruption methods •French press (pressure cell) and highpressure homogenizers. In these devices, the cell suspension is drawn through a check valve into a pump cylinder. At this point, it is forced under pressure (up to 1500 bar) through a very narrow annulus or discharge valve, over which the pressure drops to atmospheric.
