An Introduction to the Centrifuge

JoVE 5019

The centrifuge is an instrument used in nearly every research lab across the globe. Centrifugation is the process by which a centrifuge is used to separate components of a complex mixture. By spinning laboratory samples at very high speeds, the components of a given mixture are subjected to centrifugal force, which causes more dense particles to migrate away from the axis of rotation and…
