What is compact cryogenic storage and how can IVF laboratories maximise their storage density?

Compact cryogenic storage refers to the use of storage consumables and vessel configurations that maximise the number of samples held within a given dewar capacity, reducing the need for additional storage vessels as a programme’s inventory grows. For IVF laboratories managing increasing embryo, oocyte, and sperm storage volumes, compact cryogenic storage strategies directly affect both operational costs and the physical infrastructure requirements of the cryogenic storage room.

The primary tools of compact cryogenic storage are half-size cryogenic canes and compact cryosleeve covers. Standard full-length canes occupy the full height of a canister with a single cane unit per position. Half-size canes allow two cane units to occupy the same canister position, doubling the number of separately retrievable cane units per canister.

Vessel selection is the upstream decision that determines the maximum possible storage density. Dewars with wide-bore canisters and high-density racking systems accommodate more canisters per unit of vessel capacity than narrow-bore or low-density configurations. When specifying a new storage vessel for a growing programme, reviewing canister configuration and cane capacity alongside the headline litre capacity of the vessel is essential for accurate capacity planning.

Cryocanes are metal racks designed to hold visotubes inside liquid nitrogen tanks, offering an efficient way to manage large numbers of samples, and IVF cryocane storage solutions provide structured placement, reducing the risk of sample misidentification, while high-capacity cryocanes for storage allow laboratories to store a greater number of samples securely.

Vapour phase storage vessels, which maintain samples above the liquid nitrogen surface rather than submerged in it, can achieve high storage densities while providing the additional benefit of eliminating cross-contamination risk through the liquid medium.
