Assemblies and methods process cord blood in a sterile fashion to avoid exposure to bacterial contamination. A transfer tube couples a cord blood processing container to an other container, which, in use, holds a cryopreservative solution. The transfer tube has an interior diameter that is restricted substantially along its entire length, to meter the introduction of cryopreservation solution into cord blood at a desired rate, thereby avoiding damage or trauma to the cord blood cells.
