The Fisher Scientific Marathon 21000 series units are high-speed, multi purpose centrifuges, used in medical, industrial, and scientific applications. The Marathon 21000 Series is available in two models:ventilated (21000) and refrigerated (21000R). Both models accommodate swinging bucket or fixed angle rotors. They can process a variety of tubes, bottles, and microsample tubes. Swinging bucket styles feature a 4 x 250 mL or microplate carrier rotor. The microplate rotor can process both standard and deepwell microplates. Fixed angle styles include a 6 x 85 mL, an 8 x 28 mL or a microtube rotor.

The Marathon Series features a maintenance-free, brushless motor, and an easy-to-use front panel, which provides three versatile timing modes: automatic timed run, short spin (momentary), and hold (continuous mode). Acceleration and brake rates may be controlled, to optimize runs: rapid for fast separations or slow for delicate samples. Repeat runs, with the same speed and time settings, may be achieved at the touch of a key.
