- Frequency-controlled, air-cooled direct-drive induction motor
- CFC-free cooling system
- Overspeed safety system
- Dual purpose digital display
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.

GMI is a great source for used and refurbished lab equipment. GMI takes a lot of pride in their work and it feels more like the security of buying new equipment rather than used. Their service people are nice and easy to work with and Jason B. is a friendly, responsive sales person.
We bought an old Beckman floor model centrifuge earlier this year and it’s been running wonderfully. When the motor drive belt broke, they had a new belt to us in a couple of days. Easy peasy
