  • Systems that prevent operation of continuous flow ultra-centrifugation systems without simultaneous contact of a single safety sensor and a control icon
    Patent number: 10773263
    Abstract: A system is provided that includes a controller in a control cabinet, a touch screen having a plurality of control icons, a controlled device, and a single safety sensor. The controlled device is a continuous flow centrifugation system. The controller prevents operation of the controlled device without simultaneous contact by a user of both the single safety sensor and a respective one of the plurality of control icons.

  • Continuous flow ultra-centrifugation systems
    Patent number: 9405836
    Abstract: A continuous flow centrifuge system is provided. The system includes a rotor, a stator, a stator housing, upper and lower bearing plates, upper and lower bearings, first and second snap rings, and lip seal. The upper bearing rotatably secures a shaft of the rotor in the upper bearing plate. The first snap ring secures the upper bearing to the rotor shaft. The lip seal is over the upper bearing and forms a rotatable seal with the upper bearing plate. The second snap ring secures the lip seal to an inner diameter of the upper bearing plate. The upper and lower bearing plates are secured to the stator housing so that the rotor is operatively aligned with the stator.
