CryoStork V2, V3 or V10: Which Dry Shipper Does Your IVF Lab Actually Need?

Most IVF lab dry shipper selection decisions are made on capacity. They should be made on hold time.

A dry shipper's capacity tells you how many canes or canisters it can carry. Its hold time tells you how long it can maintain the temperature required to keep your samples viable. For a same-day domestic transfer, these two specifications lead to the same decision. For anything longer, capacity becomes secondary.

Cryolab's CryoStork range covers three models. The V2 is compact and lightweight, designed for single-patient and courier-based transfers. The V3 handles routine inter-clinic transfers carrying one to three patients per journey and is the most widely used model in UK fertility clinics. The V10 is the high-volume option, suited to sperm banks, fertility networks, and transfers requiring extended hold times.

All three operate in LN2 vapour phase — no free liquid nitrogen during transit, IATA-compliant for air freight, no PI 650 dangerous goods declaration required.

Before any transfer on any model, perform the inversion test. Hold the fully charged vessel inverted for 10 seconds. If no liquid nitrogen exits, the charge is complete. If it does, return the vessel to the nitrogen bath for further charging. This test takes 10 seconds. Skipping it is the single most common cause of avoidable temperature excursion during embryo transport.
