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:
In the United Kingdom, these are better known by their initials RCD, and a combined RCD+MCB is known as a RCBO (residual-current circuit breaker with overcurrent protection).In Australia, they are sometimes known as safety switches or a RCD.esidual-current and overcurrent protection may be combined in one device for installation into the service panel; this device is known as a GFCI (ground fault circuit interrupter) breaker in the USA and Canada, and as an RCBO (residual-current circuit breaker with overload protection) in Europe.
