• For a horizontal (swing-bucket) centrifuge, the recommended spin time is 10 minutes. • For a fixed-angle centrifuge, the recommended spin time is 15 minutes. A minimum g-force is required to get the gel moving, thus the recommendation is 1000 g.1, 5 • During the centrifugation process, centrifugal forces are applied to the gel in the tube.
