It's one of the most recurrent questions, I have faced during my work. As it was kindly given before, there is an equation to follow to pass from RPM to G. The most important is the radius of the rotor. it changes tremendously between big and small centrifuges, so after you do the conversion it applies only on the said centrifuge brand type.
Thank you very much. This question is always repeated due to its great importance. Because most of the samples pass through this stage in most analysis methods. Thank you very much your reply was excellent and misplaced.
