Centrifuge Rotors and Rotor Lids

Centrifuges can be divided into types based on their rotor design: fixed angle, swinging bucket and continuous flow. Choice of centrifuge rotor and lid will depend on application. Fixed-angle centrifuges hold the sample containers at a constant angle relative to the central axis and are used primarily for differential centrifugation. Swinging head (or swinging bucket) centrifuges, have a hinge where the sample containers are attached to the central rotor and are used primarily for gradient work. Continuous flow centrifuges don't have individual sample vessels and are used for large volume batch separations. Look for rotors that are easily attached, exchangeable and allow access for cleaning. Be sure to check if your intended rotor is compatible with your centrifuge’s manufacturer.
