Cryo shipping is more than logistics — it is a promise to keep biological samples safe at temperatures that preserve life itself. For fertility clinics and patients worldwide, ARKGlobal delivers that promise with scientific precision and genuine compassion.
What Is a Cryogenic Dry Shipper?
A dry shipper is a vacuum-insulated container that uses liquid nitrogen vapour (not liquid nitrogen) to maintain extreme cold. The nitrogen is absorbed into porous material inside the vessel, making it safe for commercial air travel while keeping samples below -150°C for 5–7 days without refilling.
Why Temperature Control Matters
Vitrified embryos and eggs exist in a glass-like state that is stable only below -150°C. If the temperature rises above approximately -130°C, ice crystals can form and damage cell membranes — sometimes without visible signs until thaw. This is why continuous real-time monitoring, not just end-point checks, is essential for cryo shipping.
