Caution
Never overfill liquid nitrogen
vessels. Liquid nitrogen level
should never be above the
tops of the racks inside the
vessel. The excess weight
will 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
failure.
Do not tamper with or
remove vacuum port (cov-
ered by a black plastic cap
on side of vessel); this will
void warranty.
Do not spill liquid nitrogen on
vacuum port - this can cause
vacuum failure.
Always keep liquid nitrogen
vessel in an upright position.

sel for transport.
