SORVALL( Superspeed centrifuge rotors are available in over 30 different versions. High-performance fixed-angle Superspeed rotor varieties include SUPER-LITE( aluminum models that weigh up to 50% less than conventional metal rotors, offering higher top speeds together with faster acceleration and deceleration times. SORVALL SUPER-LITE composite rotors weigh even less, and offer capacities to 6 L for fast, efficient, large-volume cell pelleting. Construction from exclusively composite materials ensures greater corrosion resistance and longer rotor life. Unique RX( Rapid Access fixed-angle Superspeed rotors employ a novel rotor lid assembly that enables faster access to samples with fewer handling steps. The lid assembly can be attached or removed in seconds while the rotor body is in the centrifuge chamber. Swinging bucket rotors offer capacities to 3 L for gentle sedimentation of different cell types. All commonly used tubes, bottles, centrifugal filtration and purification devices are accommodated, and microplate carriers enable processing of microwell plates, PCR plates and PCR tube strips.
