Beckman Optima L-90K Ultracentrifuge, 90000 RPM, Beckman Coulter (CAT#: STEM-LCPO-0105-LGZ)

The Beckman Optima™ L-90K Ultracentrifuge provides the fastest separations in the shortest time with a performance capacity of 694,000 x g and speeds up to 90,000 rpm. This versatile floor model is compatible with a wide range of advanced rotors, including partitioned and continuous flow for large volume separations.

The L-90k features an unbalance tolerant driver, and its high-efficiency vacuum-encapsulated induction driver provides unmatched reliability, allowing for smooth and quiet performance. Additionally, this ultracentrifuge model is sized for efficient operation inside a laminar flow hood.

The Beckman L-90K is equipped with an easy-to-use, environmentally friendly and microprocessor-based controlled cooling system that eliminates the use of chlorofluorocarbons and other hazardous liquid refrigerants. This Beckman centrifuge also has an overspeed system to ensure the rotor does not exceed maximum speed.

Additional features of the Beckman Optima™ L-90k centrifuge include a digital display and control via touch-sensitive keys, selection of slow start and standard acceleration, built-in w2t integrator, air-cooled driver, and CFC-free thermoelectric cooling and heating modules.
