CryoStork® Dry Shippers

CryoStork® Series is Cryolab’s range of dry shippers for the cryogenic transport of embryos, oocytes, and sperm in the LN2 vapour phase. Supplied to IVF clinics, fertility centres, NHS trusts, sperm banks, and reproductive research institutions worldwide. All CryoStork® models operate without free liquid nitrogen during transit. The inner absorption matrix retains the cold mass needed to maintain cryogenic temperatures, so the shipper itself travels as not restricted under IATA Special Provision A152, provided the packaging cannot build pressure or release nitrogen in any orientation and the air waybill is annotated accordingly. Packing Instruction 650 is a separate requirement covering the biological samples inside where those are classified as UN 3373 Category B, not the nitrogen holding them cold.
