A transportation system for transporting a biological material container between a sterile field and a nonsterile field and substantially maintaining sterility of the biological material container includes a housing assembly that removably houses the biological material container. The system also includes a port defined by the housing assembly, and the port provides communication into the biological material container from outside the housing assembly. The housing assembly includes a first member that covers a first portion of the biological material container such that a second portion of the biological material container extends from the first member. The housing assembly also includes a second member that covers the second portion of the biological material container. The second member is removably coupled to the first member to expose the second portion of the biological material container. A keying member that keys the transportation system in a centrifuge is also disclosed.
