Web• Cells in different growth stages have different physical properties. Cells in a culture can thus be physically separated based on their density or size, for instance. This can be achieved using centrifugation (for density) or filtration (for size). • In the Helmstetter-Cummings technique, a bacterial culture is filtered through a membrane.
