Centrifuges

RPM is the rotor speed, while RCF describes the actual relative centrifugal force applied to the sample. The same RPM can produce different RCF values depending on rotor radius.

Refrigerated models are useful when samples are temperature-sensitive, when runs are long, or when protocols need controlled cold conditions during separation.

Fixed-angle rotors are common for routine pelleting and faster spins, while swing-bucket rotors are often chosen for applications that benefit from horizontal sample orientation during separation.

Confirm the tube format, maximum volume, adapter requirements, and the rotor positions needed for the actual workload so the centrifuge matches day-to-day sample handling.

Use a level bench, balance tubes carefully by mass, match tubes and adapters correctly, and keep the rotor, lid, and bucket hardware clean and properly seated.
