HR21M Floor-Standing Refrigerated High-Speed Centrifuge, 21,000 rpm (CAT#: STEM-AL-4262-ZJF)

HR21M Floor-Standing Refrigerated High-Speed Centrifuge is designed for high-speed separation and concentration of biological and laboratory samples. The instrument reaches a maximum speed of 21,000 rpm. The documented maximum relative centrifugal force is 53,741 × g. The rotor system supports angle, continuous-flow, swing-out, and microplate rotors. Electronic control manages speed, time, and stored operating methods. The AC variable-frequency motor provides stable rotation during acceleration, running, and deceleration. Safety functions monitor operating conditions such as overspeed, imbalance, temperature, and door status where applicable. The chamber and enclosure are arranged for routine loading, cleaning, and laboratory operation. The centrifuge supports repeatable sample separation within the documented rotor, load, and environmental limits.
