1. An open ended cylindrical connector to affect the transfer of material between two containers comprising:

  • a) container docking ports at both ends of the cylindrical connector; and

    b) a unidirectional substantially open ended hole-cutter located between and aligned co-axially with said container docking ports with the cutting-edge facing a first container docking port, said docking parts being respectively adapted to receive a neck of a donating container, at the first docking port, and a neck of a receptor container, at a second docking port, thus incorporating both containers into a single closed system;

    wherein the unidirectional substantially open hole-cutter includes a plurality of half-arches, the outer surfaces of which are formed as a cutting edge, radiating out from the central axis of the cylinder with rotational symmetry to form a skeletal dome; and

    a pointed membrane piercing spike mounted centrally on top of the conjunction of the half-arches.
