Overview :
The centrifugal force in a centrifuge is dependent on the
rotating speed and the diameter of the rotation. If a given centrifugal force
is needed and the rotation characteristics are known, it is possible to
calculate the speed required to attain the needed force.
relative centrifugal force in gravities =
= 0.00001118 * (rotating radius) * ((rotating speed)^2)
where:
• The rotating radius is in centimeters. This is the
horizontal distance from the center of the rotor axis to the tip of the
centrifuge tube.
• The rotating speed is in revolutions per minute (rpm).
The rotating speed to achieve a given centrifugal force =
= (square root (89445 * (relative centrifugal force desired)
/ (rotating radius)))
