The Beckman Optima™ LE-80K Ultracentrifuge offers the fastest separations possible in the minimum amount of time with its performance capability of up to 80,000 rpm. This versatile model is compatible with a wide range of superior rotors and tubes. Capable of rapid run times, the Optima™ LE-80 K is perfect for a broad range of applications.
Featuring a high tolerance of rotor imbalance, this Beckman centrifuge uses a frequency-controlled, air-cooled, direct-drive induction motor that requires no brushes or gears. Operators are assured of smooth and quiet performance with this externally forced-air cooled and internally oil cooled unit.
Equipped with easy-to-use, environment-friendly and microprocessor–based control cooling systems, the Beckman LE-80 K eliminated the use of CFCs and other dangerous liquid refrigerants. This Optima centrifuge is operated through a keypad control panel, and digital display which shows parameters including rotor speed, run time, rotor temperature, w2t value, and selected program number. The display has a dual purpose, indicating both actual values/conditions and set values.
Other features of the Beckman Optima™ LE-80 K centrifuge include automatic standby mode, overspeed and purge system, LED run indicators, and diagnostic messages. Its design includes a high strength structural steel chamber door with a solenoid interlock which prevents it from opening during operation. The LE-80K has an aluminum rotor chamber, coated with a chemical-resistant epoxy finish.
