Beckman Coulter Optima L-90K Ultracentrifuge

Beckman Coulter Optima L-90K Ultracentrifuge


This Beckman Coulter Optima L-90k Ultracentrifuge has been fully tested, inspected and verified to be in great working condition.  

90 Day Warranty!

Includes: Beckman Coulter Optima L-90K Ultracentrifuge, Power Cord, 4 Feet & 2x Keys

Note: A rotor is not included because every lab has different needs. The rotor shown (50 ti) was used to show the centrifuge working during pictures. Prior to de-installing the unit from our clients' lab, we used their rotor to verify and test it to 90,000 rpm. They wanted to keep the rotor and the shown 50 TI is the highest rpm rotor, for this class of centrifuge, that that we currently have in stock. If you would like the rotor, please contact us.

The Beckman Optima™ L-90K Ultracentrifuge offers the fastest separations possible in the minimum amount of time with its performance capability of 694,000 x g at up to 90,000 rpm. This versatile floor model is compatible with a wide range of superior rotors including zonal and continuous flow for large-volume separations. The Optima™ L-90 K is perfect for applications such as subcellular particles and virus isolations, and high-purity plasmid DNA.

Featuring an imbalance-tolerant drive, the L-90 K provides unmatched reliability with its highly efficient vacuum-encased induction drive which allows smooth and quiet performance. Plus, this ultracentrifuge model is sized for efficient operation within laminar flow hoods.

Equipped with easy-to-use, environment-friendly and microprocessor–based control cooling systems, the Beckman L-90 K eliminated the use of CFCs and other dangerous liquid refrigerants. This Beckman centrifuge also has an overspeed system to ensure that rotors do not exceed maximum speed.

Other features of the Beckman Optima™ L-90 K centrifuge include digital displays and control via touch-sensitive keys, choice of slow-start and standard acceleration, built-in w2t integrator, air-cooling drives, and CFC-free thermoelectric cooling and heating modules.
