Unpacking
Section 3
Note The most prevalent cause of failure of liquid nitrogen storage vessels
is mechanical. The vessel neck tube supports the full weight of the inner
shell and all liquid nitrogen it contains. A side or corner blow to the vessel
causes the inner shell to swing in a pendulum motion causing the neck
tube to be damaged. Any storage vessel which has been exposed to an
accident, has been dropped or lowered to hit on one corner will tend to
fail more rapidly than one which has not.

Before using your new vessel, carefully inspect it. Check for signs of
damage which may have occurred in shipment. It is advisable to fill (see
Filling Instructions) all new units with liquid nitrogen and watch liquid
nitrogen loss rate for a few days. If there are any problems, call Technical
Services as soon as possible.
The Warranty Registration card enclosed with the vessel must be
completed and returned to Thermo Scientific within 30 days to make
warranty effective. This information must include the serial number which
is located on the handle of the vessel or on the label located on the
opposite side of the Arctic Express logo.
