Several rotors are available, including a popular 4 position swinging bucket rotor with a wide offering of accessories for the centrifugation of tubes, bottles, plates and blood bags. The high capacity rectangular buckets accept microplates directly or a variety of tube inserts foraccomodating as many as 40 x 50ml conical or 96 x 15ml conical tubes per run. Advanced microprocessor controls allow for instant rotor identification, which automatically converts the rotational speed to the relevant g-force (rcf), preventing the user from setting a speed above the capabilities of the installed rotor. In addition to retrieving up to 99 saved programs, the easy to use front panel can adjust accel/decel rates, time, and convert operation between rpm and rcf. The powerful refrigeration system, with a range of -20 to 40C, also features a precool function that ensures the temperature of the chamber is optimized for any application. A standard floor stadning model is available (height: 38.6 in.) which includes a convenient lower drawer for te storage of frequently used rotors and accessories. In addition, a space saving underbench model (height: 27.5 in.) is available when under the counter storage is preferred. Both models are equipped with wheels for easy maneuverability around the laboratory. For all your high capacity, high volume needs, the Z496-K floor standing series is the perfect centrifuge.
