Abstract: The present invention relates to an RFID cap for a cryogenic vial, the RFID cap comprising a cap body; and an RFID tag attached to the cap body, the RFID tag comprising an RFID chip and an antenna connected to the chip. The present invention also relates to an RFID box lid for a cryogenic vial storage box having an array of storage slots capable of receiving cryogenic vials; the RFID box lid comprising: a box lid body; and an array of RFID tags positioned on the box lid such that when the box lid is located on the storage box, each RFID tag in the array is aligned with a storage slot in the box.

Abstract: An RFID tag for location inside a tubular base portion of a freestanding cryogenic vial, the RFID tag comprising: an RFID chip; an antenna connected to the chip; a support medium configured to support the chip and connected antenna; and a plug at least partially surrounding the chip, the antenna and the support medium, the plug being shaped to engage the tubular base portion of the vial. The RFID tag may be used to retrofit vials already stored at cryogenic temperatures.

Abstract: An RFID interrogation probe (1) comprises a ring shaped housing (2), having a maximum thickness (I) (measured along its cylindrical axis) which is less than the innermost diameter (di) of the housing, and a looped antenna (3) housed within the ring shaped housing.

Abstract: A sleeve for a cryogenic straw, the sleeve comprising an RFID tag.
