UK fertility clinics typically source cryogenic equipment and liquid nitrogen through separate supply chains. Liquid nitrogen is supplied by industrial gas companies operating national distribution networks, delivered in cylinders or by tanker depending on volume. Cryogenic equipment – storage vessels, dry shippers, controlled rate freezers, and consumables – is sourced from specialist laboratory equipment suppliers. The two supply chains intersect at the laboratory: the equipment supplier provides the vessels and systems that hold the liquid nitrogen the gas company delivers. For HFEA-licensed clinics, both supply relationships carry compliance implications – equipment must be appropriate for licensed use and maintained to documented standards, while liquid nitrogen supply must be reliable enough to ensure no storage gap occurs. Having a specialist UK supplier with established stock and technical support reduces supply risk significantly. Cryolab supplies cryogenic equipment to fertility clinics across the UK and internationally from its base in Chichester, West Sussex.
