Preface
Contains Parts and Assemblies
Susceptible to Damage by
Electrostatic Discharge (ESD)
Important Read this instruction manual. Failure to read, understand and follow the instructions in
this manual may result in damage to the unit, injury to operating personnel, and poor equipment
performance.
Caution All internal adjustments and maintenance must be performed by qualified service
personnel.
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.
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.
Warning Contact of liquid nitrogen with the skin or eyes may cause serious (freezing) injury.
Warning Do not roll. Always keep liquid nitrogen vessel in an upright position. Exercise caution
to prevent spilling and splashing.
