Sooner than most laboratories assume, and the deciding factor is usually control rather than cost.
The Case for Hire
A purchased shipper used a few times a year spends most of its life empty, and an empty shipper still needs storage space, inspection and charging before use. Hire also moves cost out of capital and into the shipment, which is easier to approve and easier to recharge. A one off shipment needing more capacity than your unit holds is a hire, not a reason to buy a second vessel.
Where Owning Wins
Frequency is the obvious argument, and the crossover sits lower than expected once staff handling time is counted. Control is stronger: with your own vessel you know whether it has been dropped and how it performed last time. Readiness is third, because charging is not instant and owning means preparing on your own timetable.
The full comparison is in dry shipper hire or purchase, and the range runs from V2 to V10 across the CryoStork dry shippers.
