Cryolab Identifies Consumables Specification Gap as Underestimated Risk in IVF Laboratory Practice

LONDON - Aug. 6, 2026 - PRLog -- While storage vessels, controlled rate freezers, and dry shippers are typically subject to rigorous specification and verification processes in UK IVF laboratories, the consumables that form the sample storage chain - cryocanes, cryosleeves, visotubes, and goblets - are frequently treated as interchangeable and procured on price or availability rather than performance specification.

The guidance, produced by Cryolab founder Paul Hague, who has supplied IVF laboratories with cryogenic equipment and consumables for over 40 years, outlines the specific failure modes this approach creates.

Every cryopreserved sample in an IVF laboratory passes through a chain of consumables before reaching the storage vessel. A goblet holds the visotube or straw. The goblet loads onto a cryocane. The cryocane, protected by a cryosleeve, is suspended inside the vessel. Each component must perform reliably at -195.8 degrees C and must be dimensionally compatible with the other components in the chain.

When those conditions are not met, the failures tend to be quiet: a cryosleeve that becomes brittle at cryogenic temperature and cracks during retrieval, destroying the identification label; a goblet that does not seat correctly on the cryocane, allowing sample displacement; a cryocane incompatible with the vessel's canister system, sitting at an angle and exposing samples to slightly elevated temperatures near the vessel neck.

Paul Hague commented: "The laboratories that get consumables right treat them as part of the storage system, not as a separate purchasing decision. A cryocane that does not fit the canister correctly, or a cryosleeve that fails at cryogenic temperature, does not just create a practical problem - it creates a traceability problem."

The guidance addresses specific material distinctions - including the thermal conductivity advantages of aluminium cryocanes over stainless steel at the point of liquid nitrogen plunge, and the performance advantages of biological sample sleeves over standard PVC formulations at cryogenic temperatures - alongside the compatibility requirements for goblets and visotubes across different cane systems.
