RCF vs RPM: Your Spin Speed Is Probably Wrong

Two rotors at the same RPM spin cells at very different g — convert RCF↔RPM with your rotor radius and protect your pellet.

RCF → RPM Calculator (pelleting mammalian cells in a microfuge)

Convert a target relative centrifugal force (×g) into the rotor speed (RPM) you must dial in for pelleting mammalian cells in a microfuge, from your rotor radius.

RPM → RCF Calculator (pelleting mammalian cells in a microfuge)

Convert centrifuge speed (RPM) to relative centrifugal force (×g) for pelleting mammalian cells in a microfuge, using your rotor radius. Always report ×g, not RPM, for reproducibility.

RCF → RPM Calculator (a plasmid miniprep spin)

Convert a target relative centrifugal force (×g) into the rotor speed (RPM) you must dial in for a plasmid miniprep spin, from your rotor radius.

RPM → RCF Calculator (DNA ethanol precipitation)

Convert centrifuge speed (RPM) to relative centrifugal force (×g) for DNA ethanol precipitation, using your rotor radius. Always report ×g, not RPM, for reproducibility.

RPM → RCF Calculator (pelleting bacteria)

Convert centrifuge speed (RPM) to relative centrifugal force (×g) for pelleting bacteria, using your rotor radius. Always report ×g, not RPM, for reproducibility.
