Battery operated centrifuge for cell separation in fluid suspension.


Step 9: Figuring out centrifugal force

Picture of Figuring out centrifugal force
Use of this "nomogram" allows you to determine the relative centrifugal force (RCF) in g's, by aligning the radius of rotation in mm (in this case, paper clip length for the rotor arm measured from the center of the motor spindle to the base of the bucket).

The Revolutions Per Minute (RPM) can be verified with a hand-held tachometer. We used an infra- red tachometer from Harbor Freight.
