WebAbility to control pressure in order to rupture a variety of cell types including more challenging cells such as yeast or fungi. As the name implies, high shear mixers use the mechanical force of shear to rupture cells while … Since the 1940s high pressure has been used as a method of cell disruption, most notably by the French Pressure Cell Press, or French Press for short. This method was developed by Charles Stacy French and utilises high pressure to force cells through a narrow orifice, causing the cells to lyse due to the shear … See more Cell disruption is a method or process for releasing biological molecules from inside a cell. See more The production of biologically interesting molecules using cloning and culturing methods allows the study and manufacture of relevant molecules. Except for excreted molecules, cells producing molecules of interest must be disrupted.

WebThe “French Pressure Cell” disrupts (“breaks”) the cells of microorganisms by elevating the cell suspension to a high pressure and then allowing it to escape back to ambient pressure through a small orifice. An alternative to the French Pressure Cell is the Microfluidizer, which operates on a similar principle but is suitable for much ...
