force is the weight of a particle in a centrifuge relative to its normal weight, the
centrifugal force per unit mass in gravities (g). To determine the RCF (or g) for these
procedures, consult the serology manual or a monograph. The inside of the centrifuges
should occasionally be cleaned to prevent dust particles from being blown into
specimens. The lid on the centrifuge should be closed and locked before and during
operation. Only open the lid when the centrifuge has stopped rotating.
