Beckman Coulter J2-21M High Speed Centrifuge Speed range: 0 to 21,000 rpm Max capacity: 6 x 500mL Rotors sold separately; call for info on available models 90 day warranty The Beckman J2-21 series centrifuges are built for constant day-to-day use with rugged and reliable construction. An automatic vacuum system reduces windage and provides fast rotor acceleration, accurate temperature control, faster rotor cooling, and long motor life. The Beckman J2-21M features a high torque brushless induction drive for less maintenance and longer life span. The Beckman J2-21 M features microprocessor control with programmable memory that stores 10 programs and eliminates errors in repetitive runs, along with a choice of three acceleration profiles. A rotor identification system provides overspeed protection and automatic temperature compensation for rotor windage. A digital display shows users current rpm and other status information in real time during runs. All of our equipment is used and reconditioned. Our technicians test the performance of all centrifuges and make sure the rotating assembly is properly balanced; the bearings, seals and gaskets on the spindle assembly are in good shape; and the controls work properly. If the centrifuge is refrigerated we also test to make sure that the machine reaches and hold temperature properly. All tolerances are measured and the exterior and interior of all units are fully cleaned. If the unit is being purchased with a rotor we test the rotor/centrifuge combination together.
