Webcentrifuge suppliers, or a nomogram for conversion. The k-factor is a parameter for the sedimentation distance in a test tube. This factor is also called clearing factor and represents the relative pelleting efficiency of a centrifugation system at maximum rotational speed. In general, the k-factor value is used to estimate the time, t (in hours), WebWhen a centrifuge spins, it creates a centrifugal force strong enough to rapidly separate particles in a sample. Anything with a density greater than water sinks (and sinks faster) when in a centrifuge. And anything with a density less than water rises and rises faster when in a centrifuge.
