Calculating your centrifuge’s RPM value is a very simple task. All you need is the rotation radius (or rr) and the relative centrifugal force (or RCF) values, given in the owner’s manual of the unit. Follow the procedure explained below:
- Multiply the rotation radius, usually given in millimetres, by 1.12.
- Divide the relative centrifugal force, usually in g, by the value calculated in Step 1.
- Take the square root of the value calculated in Step 2.
- Multiplication of the results from Step 3 and 1,000 will give you the RPM.
In other words:
In case the owner’s manual is missing, or the rotation radius or RCF values are not given, please contact the centrifuge’s manufacturer for details.
Example: For a rotation radius of 8 mm, and RCF of 22,400 g, the RPM is:
