Abstract: A disposable kit for use in directing fluid through a biological cell separator device (10). The kit generally includes a separator tube (22), a buffer fluid container (34), cell sample container (32), separated cell container (60), and flushing fluid container (62), as well as various conduits (36, 38, 42, 50, 50a, 50b) for connecting the containers (32, 34, 60, 62) and separator tube (22) in fluid communication together. A cell separator system is provided including a separator tube (22), magnet (20), pump (120) and a motorized drive unit (96). The motorized drive unit (96) is operatively connected to the magnet (20) to allow the magnet (20) to be moved a sufficient distance away from the separator tube (22) so as to allow cells adhered to the inside surface thereof to be flushed out of the tube (22).

Abstract: The present invention provides methods and apparatuses for determining at least one of a plurality of particle physical characteristics. The particle physical characteristics include particle size, shape, magnetic susceptibility, magnetic label density, charge separation, dielectric constant, and derivatives thereof. The method includes generating a region of space having a substantially constant force field, determining the velocity of at least one particle within the region by identifying and locating the particle and its coordinates in at least two temporally defined digital images, and determining the particle physical characteristics from the determined velocity and a predetermined force field magnitude and direction.
