  • Patent number: 10519409
    Abstract: A fluid transfer assembly for single use bioreactors includes a fluid transfer housing that can be mounted to the impeller shaft using a bearing that places the fluid transfer assembly directly below the lowest impeller but allows the impeller shaft to spin inside independently of the fluid transfer assembly. A fluid conduit connects the fluid transfer housing to a port in the single use bag wall which allows fluids to be introduced into the sparger and which also helps prevent the fluid transfer assembly from rotating with the impeller shaft.

  • Patent number: 10335750
    Abstract: The system and method of the invention pertains to use of a back iron on one or both ends of the impeller to increase the magnetic field density, and thus strengthen the magnetic coupling. In addition, pie-shaped (i.e. wedge) magnets, or variations thereof, increase the utilization volume and hence provide higher torque to allow the use of less expensive material (e.g. ferrites). In another embodiment, the rotor side is constructed with a Halbach array which increases the torque without the need to add a back iron piece. In another embodiment, an axial flux stator is implemented to replace the drive-end magnets and the drive motor.
