What is Centrifugal Elutriation

Centrifugal elutriation was invented by Charles Lindberg in the 1930s. This technique continuously separates cells according to their sedimentation velocity using a specialized centrifuge rotor. A specialized rotor loads cells into a spinning elutriator chamber introducing an opposing directional buffer (opposite direction of centrifugal force) to fractionate the cells.
