Product Description Easy-to-use touch screen UI 90000 rpm Imbalance tolerant drive GMI is the #1 seller for Re-Certified Ultras in the US Did you know GMI sells BRAND NEW Ultracentrifuges GMI services all Beckman Ultracentrifuges This Beckman Optima XE-90K Preparative Ultracentrifuge is GMI Certified It is a current model preparative model centrifuge used for pelleting fine particulate fractions such as nucleic acids, DNA, cellular organelles, microsomes, and viruses. Whats under the hood is the same Optima reliability of the entire ultra line. This Beckman ultracentrifuge can also be used for gradient separations and protein purification, and features a dynamic temperature regulation system which efficiently maintains optimal processing temperature. Designed with a shallow rotor recess, the Optima XE-90K offers most users a convenient operating height. The vacuum encased induction drive is essentially frictionless and will provide YEARS of trouble free operation-the pretty much dont wear out! The big change in the XE line and specifically the Optima XE-90K system is that it is equipped with a touch screen interface which enables the user to manage and control temperature, RPM, accel/decel, and time settings. RPM settings are allowed to reach up to 70,000. The XE Series operates using the Dynamic Rotor Inertia Check (DRIC) function. This feature can recognize imbalances in the rotor, thereby preventing system failure and equipment damage before the unit performs actual separations. Other features of the Beckman Optima XE-90K centrifuge include a built-in rotor and tube catalog, intelligent logging software, dual display of set and actual run parameters, and simple user setup which involves automatic preheating, pre-cooling, vacuum, and dry cycle.
