1. A mounting adapter for a centrifuge rotor, the mounting adapter being receivable on the end of the drive spindle itself having a threaded bore therein and a frustoconical locking taper surface thereon, the mounting adapter comprising;

  • a spud member having an internal chamber therein, the chamber being defined in part by a first, locking, surface and a second, lifting, surface, the spud member having an threaded access bore and a mounting bore extending therethrough, the mounting bore being bounded by a tapered surface corresponding in shape to the frustoconical locking taper surface on the spindle, both the access bore and the mounting bore being in communication with the internal chamber; and

    a connecting member having a head and a threaded shank thereon, the head being confined within the internal chamber with the shank extending into the mounting bore, the connecting member being rotatable in first and second opposed angular directions by a tool extendable through the access bore into engagement with the head of the connecting member,rotation of the connecting member in the first angular direction threadedly engaging the shank with a threaded bore disposed in a drive spindle and bringing the head into abutting contact with the locking surface thereby to impose a locking force acting in a first direction on the spud member to hold the mounting surface thereon and the frustoconical surface on the spindle in locking engagement,rotation of the threaded member in the second angular direction unthreading the shank from the threaded bore in the spindle and causing the head to abut against the lifting surface thereby to impose a lifting force acting in a second, opposed, direction on the spud member to assist in separating the mounting surface on the spud member from the frustoconical surface on the spindle.
