1. A system for preparing a bone graft for implantation, comprising:

  • a container defining a reservoir and having an inlet and an outlet;

    a fluid permeable basket disposed within the container and capable of retaining a porous, biocompatible, implantable substrate, the basket comprising a tray-like device having opposed fluid permeable porous members that comprise a porous bottom surface and a porous top surface; and

    a driver mechanism coupled to the container and the reservoir, the driver mechanism being effective to subject any fluid within the reservoir to a constant force so as to induce a selected, controlled flow rate of the fluid through the container.
