WEST SUSSEX, U.K. - s4story -- Chichester-based cryogenic equipment specialist Cryolab Ltd has published a cost analysis showing that a laboratory's annual liquid nitrogen spend is determined primarily by its choice of storage vessel rather than its gas contract. Using static evaporation figures from its own product data sheets, the analysis shows a 47 litre storage dewar evaporating roughly 131 litres of liquid nitrogen a year while closed, against about 318 litres for a 175 litre racked vessel, with the larger vessel nevertheless proving around four times more nitrogen-efficient per stored sample owing to its far greater straw capacity.

The analysis includes a worked example for a laboratory storing 12,000 straws and a formula laboratories can apply to any vessel shortlist using their own contract price per litre.
