Explain the difference between "xg and "rpm in cetrifugation. Why are centrifugation rates reportedin "xg"...

Question

Why are centrifugation rates reported in "xg" and not "rpm" published protocols?

Answer 1

rpm - revolutions per minute - how many times a centrifuge will rotate per minute - self explanatory, not too accurate when it comes to published journals



rcf - relative centrifugal force - its more of a proportional constant but in laymans terms -> force calculated based on the given rotor speed and given rotor radius of a centrifuge. It is reported as x g (multiples of g - gravitational constant)

there is a formula to calculate one from the other but it also depends on the rotor of your centrifuge

Answer 2

Xg To Rpm

Answer 3

I'm not positive, but I imagine the 'xg' is how many Gs (forces of gravity) the item will be pulling. RPM simply the motor speed, not the force that the item being spun will be under.
