The relationship between RPM and RCF is as follows: g = (1.118 × 10-5) R S2. Where g is the relative centrifugal force, R is the radius of the rotor in centimeters, and S is the speed of the centrifuge in revolutions per minute. Values of RCF in units of times gravity (× g) for common microcentrifuge rotor radii appear in the following ...

RPM and G-Force: Which Is More Important and Why?
G-Force or RCF (relative centrifugal force) is the force being exerted on the rotor contents. RCF is a result of the rotor revolving so is dependent on RPM. The key attributes for the Z306 Universal Centrifuge show the max RPM and RCF for this unit. In a centrifugal process, RCF is what is affecting your samples, so it's important that this ...

Differences Between RCF & RPM in Centrifugation
Basically, it is telling us how fast the rotor is spinning. Centrifuges will have a speed range that they are capable of achieving and will vary depending on the centrifuge. A low-speed centrifuge might spin at as low as 300 RPM, while a high-speed centrifuge could spin up to 15000 RPM. Ultracentrifuges are also available and are the most ...
