ABSTRACT:
A disposable diagnostic plasma filter dispenser includes a low cost disposable container and a rotor drive for rotationally energizing a rotor within the container. The disposable container is particularly suitable for drawing and dispensing blood samples for clinical analysis and includes a tube shaped outer wall having a frangible dispenser outlet cover, a close fitting inner tube supporting a filter membrane and a unitary rotor disposed for axel free rotation and axial translation within the inner tube in response to energization from the rotor driver. The rotor produces vortex enhanced filtration while maintaining a flow of filter fluid through the filtration gap and creating a transmembrane pressure.
