  • Bowl centrifuge nozzle
    Patent number: 6511005
    Abstract: An outlet nozzle for use within a centrifuge rotor. The outlet nozzle includes an axial inlet channel and an outlet channel disposed angularly with respect to the inlet channel. An insert is received within the holder and includes an orifice portion and a directing portion. The directing portion shields at least a portion of the outlet channel for preventing impact therewith and for diverting fluid flow from the inlet channel of the holder and into the orifice portion of the insert. The insert further includes an inlet edge at a proximal end which is defined by the intersection of the outlet channel and the inlet channel.

  • Nozzle for centrifuge rotors and method of removing same
    Patent number: 6216959
    Abstract: A nozzle removal assembly including an outlet nozzle for centrifuge rotors and cooperating hand tool. The nozzle has an improved structure for facilitating the installation within and removal from a rotor wall. The centrifuge nozzle includes a body portion having inlet and outlet ends wherein the outlet end includes a placement channel. The placement channel defines a radially inwardly facing engagement surface supported externally to the rotor wall for engagement with a hand tool. The hand tool is adapted for engaging the radially inwardly facing engagement surface of the placement channel wherein both rotational and axial forces may be applied to assist in the removal of the nozzle from the rotor wall.
