A system for the remote live auditing of biological samples while contained in a vessel filled with coolant fluid, the system comprising: one or more canisters, each of which comprises a connector and is configured to hold at least one container, each of which contains one or more biological samples and has associated therewith an RFID tag identifying the container in question; a docking assembly mountable on said vessel and comprising a plurality of connectors, each of which is configured to engage with the connector of one of said canisters, thereby providing an electrical connection between the docking assembly and the canister in question; wherein each canister is operable to wirelessly interrogate the RFID tags of the containers held therein, to receive information identifying the containers as a result of said interrogation, and to communicate this identifying information to the docking assembly via said electrical connection between the canister in question and the docking assembly; wherein each canister comprises: a receptacle portion, within which said containers are held, the receptacle portion including an antenna configured to receive identifying information from the RFID tags of the containers held within the receptacle portion sent in the form of electromagnetic radiation; wherein each canister further comprises an elongate member attached at one longitudinal end to said receptacle portion and attached at the other longitudinal end to said connector; characterized in that an electrical connection between the antenna of the receptacle portion and the connector of the canister is provided by an elongate conductor arranged internally and along the length of the elongate member; wherein said elongate conductor is provided internally of a layer of electrically and/or thermally insulating material. one or more canisters, each of which comprises a connector and is configured to hold at least one container, each of which contains one or more biological samples and has associated therewith an RFID tag identifying the container in question; a docking assembly mountable on said vessel and comprising a plurality of connectors, each of which is configured to engage with the connector of one of said canisters, thereby providing an electrical connection between the docking assembly and the canister in question; wherein each canister is operable to wirelessly interrogate the RFID tags of the containers held therein, to receive information identifying the containers as a result of said interrogation, and to communicate this identifying information to the docking assembly via said electrical connection between the canister in question and the docking assembly; wherein each canister comprises: a receptacle portion, within which said containers are held, the receptacle portion including an antenna configured to receive identifying information from the RFID tags of the containers held within the receptacle portion sent in the form of electromagnetic radiation; wherein each canister further comprises an elongate member attached at one longitudinal end to said receptacle portion and attached at the other longitudinal end to said connector; characterized in that an electrical connection between the antenna of the receptacle portion and the connector of the canister is provided by an elongate conductor arranged internally and along the length of the elongate member; wherein said elongate conductor is provided internally of a layer of electrically and/or thermally insulating material.
