Cryogenic Storage Specialists Explain Critical Dewar Selection Factors for UK Laboratories

WEST SUSSEX, U.K. - April 2, 2026 - PRLog -- Selecting appropriate liquid nitrogen storage vessels requires understanding specifications that directly impact sample viability, according to cryogenic equipment supplier Cryolab Ltd.

"We regularly encounter facilities that purchased dewars based solely on volume capacity," explains a Cryolab technical specialist. "Static evaporation rate and vacuum warranty duration matter far more than advertised litre capacity."

The company recommends UK laboratories assess three critical factors before purchasing:

Vacuum Performance: Quality vessels maintain static evaporation under 0.3 litres daily. Substandard insulation can triple nitrogen consumption whilst risking temperature excursions during low-level periods.

Organisational Capacity: Proper canister-and-cane systems enable rapid sample retrieval without extended lid-open time. A 47-litre dewar with six canisters provides better organisation than a 50-litre vessel with three.

Consumables Compatibility: Storage systems should accommodate standard CBS straws and vitrification carriers without modification.

Cryolab supplies CryoNest and CryoCan dewar ranges from 20-95 litres, alongside complementary equipment including sperm analysis systems and vitrification consumables. The ISO 9001:2015 certified company has served UK fertility and veterinary sectors since 2000.
