RPM vs RCF. This is how centrifuge manufacturers generally describe how fast the centrifuge is going. The rotor, regardless of its size, is revolving at that rate. The force applied to the contents varies by the size of the centrifuge rotor. RCF (relative centrifugal force) is measured in force x gravity or g-force. This is the force exerted on the contents of the rotor, resulting from the revolutions of the rotor. It is RCF, not RPM that separates aqueous solutions in the centrifuge. RPM can be calculated for any centrifuge by this equation:
RIF is defined as an abbreviation for reduction in force and means for a job function to be eliminated. An example of a RIF is when a factory changes machinery and the operators of the old machines are no longer necessary. the act of dismissing an employee, esp. from a government job, as by eliminating the position.
