Overview
In biology and chemistry, the force felt by a sample in a centrifuge is expressed as RCF (G-force). This value depends on both the rotational speed (RPM) and the distance from the center (radius).
💡
Pro Tips
Radius should be measured from the center of the rotor to the bottom of the centrifuge tube (r_max).
Always ensure the centrifuge is balanced before starting—uneven loads cause dangerous vibrations.
Protocols often specify 'G-force' rather than 'RPM' because it is universal across different machines.

Fun Facts
"Ultra-centrifuges can reach speeds over 100,000 RPM and forces over 800,000 G."
"Centrifuges are essential for separating plasma from blood cells."
"The 'center of rotation' is fixed, so the force is technically the centripetal force holding the sample in its path."
