Preface
Contains Parts and Assemblies
Susceptible to Damage by
Electrostatic Discharge (ESD)
CAUTION
Important Read this instruction manual. Failure to read, understand and follow instructions in this manual may
result in damage to the unit, injury to operating personnel, and poor equipment performance. s
Caution All internal adjustments and maintenance must be performed by qualified service personnel. s
Caution It is recommended to have this vessel tested by the manufacturer or qualified cryovessel service
technician every 7-10 years, regardless of any problems (or lack thereof) you may have had in the past.
This will help insure your samples against sudden loss of liquid nitrogen due to vacuum failure. s
Warning Nitrogen gas can cause suffocation without warning. Store and use liquid nitrogen only in a
well-ventilated place. As the liquid evaporates, the resulting gas displaces the normal air in the area.
(The cloudy vapor that appears when liquid nitrogen is exposed to the air is condensed moisture, not
the gas itself. The issuing gas is invisible.) In closed areas, excessive amounts of nitrogen gas reduces the
concentration of oxygen and can result in asphyxiation. Because nitrogen gas is colorless, odorless, and
tasteless, it cannot be detected by the human senses. Breathing an atmosphere that contains less than
19.5% oxygen can cause dizziness and quickly result in unconsciousness and death. Therefore, the use
of oxygen monitoring equipment is strongly recommended. s
Warning Contact of liquid nitrogen with the skin or eyes may cause serious (freezing) injury. s
Warning Do not roll. Always keep liquid nitrogen vessel in an upright position. Exercise caution to
prevent spilling and splashing. s
Material in this manual is for information purposes only. The contents and the product it describes are subject

Cryogenic Storage Vessel 1-1Thermo Scientific
Please Read
Section 1 Safety Information
This manual contains important operating and safety information. The
user must carefully read and understand the contents of this manual prior
to the use of this equipment.
Your Thermo Scientific cryogenic vessel has been designed with function,
reliability, and safety in mind. It is the user’s responsibility to install it in
conformance with local electrical codes. For safe operation, please pay
attention to the warnings and cautions throughout the manual.
All cryopreservation vessels, regardless of who manufactures them, use a
vacuum to provide the super insulative properties needed to keep nitrogen
in a liquid form. They are very similar, in fact, to the Thermos® vessels you
may have used to store coffee, soup or milk.
Remember how fragile they were? Since no vacuum is perfect or will last
forever, we suggest that you monitor the consumption of liquid nitrogen
used by your vessel on a regular basis, i.e. every 1-2 days. By monitoring,
you may be able to anticipate subtle changes in consumption and possibly
react to problems before they arise. You may opt to use a level monitor for
this purpose (see page 6-1 for level monitor operation.).
Also, if your samples are super critical, one-of-a-kind, or irreplaceable,
consider allocating your samples to 2 separate vessels. Remember the old
adage about placing all your eggs into one basket….
Finally, because no vacuum will last forever, have your vessel tested by the
manufacturer or a qualified cryovessel service technician every 7-10 years,
regardless of any problems (or lack thereof) you may have had in the past.
This will help insure your samples against sudden loss of nitrogen due to
vacuum failure.
Do not use this product for anything other than its intended usage.
Use of the equipment in a manner not specified by the manufacturer may
impair the protection provided by the equipment.
General Usage

1-2 Cryogenic Storage Vessel Thermo Scientific
Section 1
Safety Information
• This unit is intended to be used by trained personnel in a well-
ventilated environment.
• Liquid nitrogen is extremely cold; it boils at -196°C.
• Follow all necessary precautions and warnings relevant to applicable
hazards such as frostbite, contact burn, asphyxiation, etc. in cryogenic
area.
• To avoid injury due to frostbite or ruptured vials, use extreme care
whenever handling liquid nitrogen, liquid nitrogen storage or transfer
vessels, or any objects which have come in contact with liquid
nitrogen.
• Leave no areas of skin exposed.
• Wear appropriate PPE where necessary; face shield, cryogenic gloves,
cryogenic apron.
• Do not tightly seal liquid nitrogen containers or prevent nitrogen gas
from escaping.
• Always handle ampules with tongs. They may explode when removed
from the vessel.
• Use extreme care to prevent spilling and splashing liquid nitrogen
during transfer and removal of storage contents and holders.
• Immediately remove any clothing or safety attire on which liquid
nitrogen has been spilled or splashed.
• Get immediate medical attention for any frostbite injuries due to
liquid nitrogen.
Warnings

• Only use the power supply provided by the unit.
• Never overfill liquid nitrogen vessels. 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 failure.
• 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 vacuum port - this can cause vacuum
failure.
• Always keep liquid nitrogen vessel in an upright position.
• Do not use this Locator vessel for transport.
