Features of Optima L-90K
  • Putting a smart new spin on your research.      The innovative rotors we've built for the Optima L are designed, manufactured and tested as a system from the inside out to make sure you get the highest quality of separation in the shortest possible time-safely and reliably. The increased efficiency of our SW 32 Ti series rotors can reduce run times. And thanks to a slight angle that positions contaminants away from the bands of interest, our NVT rotors deliver the highest purity in the shortest possible time.     
  • Innovative drive technology.      Optima L utilizes the most advanced materials and technology to achieve the high performance needed - up to 100,000 rpm - for extending the boundaries of research. Plus, the air-cooled design of our drives delivers the most energy-efficient ultracentrifugation system ever made. And the imbalance-tolerant Optima L drive safely accommodates tubes that are under- or over-filled by as much as 10%.     
  • The best place for your samples.      Since they're specially designed for innovative application solutions, our tubes deliver improved efficiencies, including Quick-Seal® for biocontainment, g-Max™ for the greatest volume efficiency, konical™ seal for the most concentrated pellet and OptiSeal™ for the easiest sealing. And the design of our one-touch OptiSeal tubes delivers fast, reliable sealing–just insert the plug and press into place, and the centrifugation process itself provides guaranteed protection for your samples.
