  • Patent number: 6001387
    Abstract: An encapsulating apparatus comprising a spinning cup adjustably rotatable about its central axis for forming droplets and projecting them radially outward, and one or more collection basins surrounding the bead forming spinning cup independently rotatable and positioned to collect the beads projected from the cup. The method for forming tissue microcapsules using the spin disk encapsulation apparatus wherein a supply mixture is introduced into a mixing chamber of the cup from a single, multiple or concentric needles. As the cup spins, the coated particles are propelled upward by the centrifugal force from the mixing chamber along the inner surface of the cup, projected radially outward, as beads, into the gelling solution in one of the selected basins.
