Beckman Coulter Optima L-90K Ultracentrifuge
The Beckman Optima L-90K Ultracentrifuge offers the fastest separations possible in the minimum amount of time with its performance capability of 694,00 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-90K is perfect for applications such as subcellular particles and virus isolations, and high-purity plasmid DNA.
Available rotors:
- 50.2 Ti (12 x 39 ml)
- 70.1 Ti (12 x 13.5 ml)
- SW28 Ti (6 x 38.5 ml)
- SW40 Ti (6 x 14 ml)

Features
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.
