With Advanced QWickTM Charge Technology

The Doble Series cryogenic liquid dewars are the first units to
be designed for both vapor shipment and liquid storage. The
Doble QWick Series utilizes an absorbent wicking material that
charges with liquid nitrogen in two hours. *New/warm tanks still
need to be filled with LN2 and allowed to sit 24 hours to achieve
maximum hold time. When a tank is already cold, the Advanced
QWick Charge technology will apply, providing the capacity for
same-day vapor shipping. A unique absorbent layer in the base
of the storage tanks enables them to be charged with nitrogen
and employed as dry shippers with hold times of up to 21 days.
Once at the final destination, the tanks can be filled with liquid
and used for long term storage, therefore avoiding the need for
return shipments.
