I hope the above information will make your calculation easy. The formula is always good to have in case your internet is down or the above links cease to exist. Print and use Nomogram (a graphical calculator). Here are several links to converters online:ģ. Science Gateway might list some centrifuges that are not found above.Ģ. Here are the links to a resources online from where you can pick up the model and rotor:īeckman, Sorvall or Thermo Fisher Scientific The most precise way to make conversion is to use converters for a particular centrifuge and a rotor head.
Use a website where you can select centrifuge model and rotor head.ġ.There are several ways to make conversion: Meanwhile, your cells might die or the biochemical reaction goes on for three times longer than it should. There is a simple formula to calculate this, but it takes some time to do the calculation. Modern centrifuges have an automatic converter but older ones do not. Therefore, you have to convert g force (RCF) into revolutions per minute (rpms) and vice versa. Unfortunately, many protocols are written in hurry and instructions are given in RPMs. It depends on the revolutions per minute (RPM) and radius of the rotor, and is relative to the force of Earth’s gravity.Ī good, precise protocol for centrifugation instructs you to use the g force rather than RPMs because the rotor size might differ, and g force will be different while the revolutions per minute stay the same. G Force or Relative Centrifugal Force (RCF) is the amount of acceleration to be applied to the sample. Rotational radius of centrifuge for converting RPM to g force (RCF).
