• To avoid injury due to frostbite or ruptured vials use extreme care whenever handling liquid nitrogen, liq-
uid nitrogen storage or transfer vessels, or any objects which have come in contact with liquid nitrogen.
• Leave no areas of skin exposed.
• Always wear proper safety attire over clothing: face shield, cryogenic gloves, cryogenic apron.

Warning
Caution
• Never overfill liquid nitrogen ves-
sels. Liquid nitrogen level should
never be above the tops of the
racks inside the vessel. The excess
weight may crack the neck and
result in vacuum failure.
• When inserting or removing
racks be careful not to come in
contact with the neck tube area
of the vessel. Remove or insert
racks slowly in a vertical manner.
Scratches on the neck tube area
can cause premature vacuum fail-
ure.
•
Do not tamper with or remove
vacuum port
(covered by a black
plastic cap on side of vessel); this
will void warranty.
• Do not spill liquid nitrogen on vacu-
um port - this can cause vacuum
failure.
• Always keep liquid nitrogen vessel
in an upright position.
• Do not use this LOCATOR vessel
for transport.
