GENERAL DESCRIPTION

The SC, XC, & LAB series container is a vacuum insulated container of aluminum with fiberglass neck construction providing you with the highest efficiency possible in liquid nitrogen storage. Use the container for inert fluids only. Liquid oxygen is not compatible with fiberglass material and should not be stored.

A sharp blow to the outer vessel can damage the neck tube or start a vacuum leak. Use caution and common sense in handling the container. Upon receipt of the container, examine it for any evidence of damage during shipping. Watch after the first fill for any signs of vacuum loss, such as frost or sweating on the outside jacket.
(Some frost near the tip just after filling is normal.)

NOTE
Fill the container with a funnel or transfer line when possible. Avoid spilling liquid nitrogen over the vacuum cap near the neck as this can shrink the seal and allow air to leak into the vacuum space.

A. CAUTION (using aluminum SC, XC, LAB series)
To avoid injury by frostbite, 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.
• Always wear proper safety attire over clothing: face shield, cryogenic gloves,
cryogenic apron
• Never overfill liquid nitrogen vessels.
• Always keep liquid nitrogen vessel in an upright position.
• Do not tightly seal liquid nitrogen container or prevent nitrogen gas from escaping.
• Use extreme care to prevent spilling and splashing liquid nitrogen during transfer.
• Immediately remove any clothing or safety attire on which liquid nitrogen has been
spilled.
• Get immediate medical attention for any frostbite injuries due to liquid nitrogen.

B. FILLING INSTRUCTIONS
To avoid damage to your aluminum cryogenic vessel which may result in premature vacuum loss it is important that the following procedure be used during the addition of liquid nitrogen to a warm vessel and on subsequent additions.
1. Slowly pour liquid nitrogen to new or warm vessels.
2. Allow liquid nitrogen to sit in covered vessel for 2 hours to completely cool inner
3. Fill your vessel to the desired level after the 2 settling (cooldown) time.
4. If you are filling your dewar from a pressurized source, make sure that the source
tank is at a low pressure (22 PSI or below).
5. If transfer hose is used for extracting liquid nitrogen from a pressurized liquid source
always use a phase separator on the end of the hose.
6. Remember to always wear proper safety attire over clothing; face shields cryogenic
gloves and apron.
7. Never overfill your dewar with liquid nitrogen. Overfilling the tank may cause
immediate or premature vacuum failure to occur.

C. MEASURING LIQUID NITROGEN QUANTITY
1. Use wooden or plastic dipstick. Never use a hollow tube to measure liquid nitrogen.
2. Level will be indicated by frostline, which develops when dipstick is removed.

D. LIQUID WITHDRAWAL
1. liquid withdrawal for the LAB units is always done by pouring or utilizing a
withdrawal device. Withdrawal device pressurizes to approximately 5 psi and the
pressure forces liquid up the withdrawal tube out the valve.
2. Always wear proper safety attire; shield, gloves and apron.

WARNING: the venting of nitrogen vapors will create a dilution of the air’s oxygen concentration necessary to support life. Exposure to this diluted atmosphere can cause asphyxiation or even death. DO NOT store or use liquid container in areas that have poor ventilation. Place liquid container outdoors or in a well-ventilated area. Failure to comply with this warning may cause serious personal injury including death.
