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

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

Safety Information

14. Use this product only in the way described in the product literature

and in this manual. Before using it, verify that this product is suitable

for its intended use. If the equipment is used in a manner not

specified by the manufacturer, the protection provided by the

equipment may be impaired.

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. To avoid personal

injury or death, DO NOT store or use liquid container in areas that have

poor ventilation. Use in a well ventilated area. Place liquid containers

outdoors or in a well ventilated area. Failure to comply with this warning

may cause serious personal injury or even death. s

Warning Extreme temperature and pressure are associated with the

Thermo 8127. To avoid serious personal injury, observe caution when

removing parts or fittings. Wear eye protection and insulated, loose

fittings gloves when removing parts or fittings. Failure to comply with

this warning may result in serious personal injury. s

Caution DO NOT use regulators, valves, gauges, hoses, etc., that have

been used in compressed air service. Failure to observe this warning could

cause serious damage to your container and possible personal injury. s

Cryogenic Transfer Vessels 2-1Thermo Scientific

Section 2 General Description

Mechanical failure is the major cause of problems associated with liquid

nitrogen storage vessels. The vessel necktube supports the full weight of the

inner vessel and the liquid nitrogen it contains. A side or corner blow to

the vessel causes the inner vessel to swing in a pendulum motion,

damaging the neck. Any storage vessel which has been exposed to an

accident, dropped, or lowered to hit on one corner, is more susceptible to

failure. Model 8127 has a support (top and bottom), but mishandling may

still cause problems. Carefully inspect your new Thermo vessel prior to

use. Check for signs of damage which may have occurred during shipment.

It is advisable to fill all new units with liquid nitrogen and watch the liquid

nitrogen loss rate for a few days. If there are any problems, call Technical

Services as soon as possible.

The on-line warranty registration address is listed on the front of this

manual. The unit should be registered within 30 days to make warranty

effective. This information must include the serial number located on the

handle of the unit.

Cryogenic Transfer Vessels 3-1Thermo Scientific

Section 3 Operation

Warning Liquid nitrogen is extremely cold; it boils at -196°C. Extreme

caution should be exercised when handling cryogenic liquids. Always wear

proper safety attire when transferring liquid ni-trogen into or out of

Thermo cylinders. Contact with a cryogenic liquid or cold gas may cause

frostbite to unprotected areas of the body. Protect eyes and skin when

transferring liquid. Stand clear of vent during filling. Loose fitting,

insulated gloves and long sleeves are recommended for arm protection.

Cuffless pants should be worn outside boots or overshoes to shed spilling

liquid. Goggles or face shields shouldbe worn if the possibility of splashing

liquid exists. Failure to observe this warning may lead to severe burns or

eye injuries. s

Caution Never overfill your Thermo dewar with liquid nitrogen. Filling

the tank up to or above the bottom of the necktube may cause immediate

or premature vacuum failure. s

To avoid damage to your Thermo cryogenic vessel (Thermo® 5, 10, 20 and

30), 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. Add only a small amount of liquid nitrogen (5-10 liters) to new or

warm vessels.

2. Allow this small amount of liquid nitrogen to sit in the covered vessel

for a minimum of 2 hours. This will limit stress caused by the sudden

temperature change associated with adding liquid nitrogen to a warm

vessel.

3. Fill your vessel to the desired level.

4. If you are filling your Thermo dewar from a pressurized source, make

sure that the source tank is at a low pressure (22 PSI or below).

5. If the transfer hose is used for extracting liquid nitrogen from a

pressurized liquid source, always use a phase separator at the end of the

hose (see Parts List for transfer hoses and phase separators).

6. Remember to always wear proper safety attire over clothing, including:

face shield, cryogenic gloves and apron.

Filling Instructions

3-2 Cryogenic Transfer Vessels Thermo Scientific

Section 3

Operation

Withdrawal Device The liquid discharge device provides liquid nitrogen for filling cold traps

and smaller dewars without having to scoop out or pour liquid nitrogen

from the vessel. The liquid discharge device utilizes the normal evaporation

of the cryogenic liquid to pressurize a container by plugging the neck of

the vessel and forming a hermetic seal. The pressurized vessel can then

decant product through the liquid discharge device. Figure 1 shows a

drawing of the liquid discharge device. The primary components of the

liquid discharge device are listed below:

Rubber Stopper: Provides a seal against the walls of the necktube.

Tightening the wingnut expands the rubber stopper.

Pressure Gauge: Indicates the pressure inside the container.

Relief Valve: Relieves pressure inside the container automatically when

excessive pressure is reached.The relief valve is a safety device and cannot

be adjusted.

Vent Valve: Provides means to vent product. The vent valve can be closed

to pressurize the vessel or opened to depressurize the vessel.

Discharge Valve: Allows product to flow out of the vessel through the

discharge device spout.

Safety Cable: Prevents discharge device from accidently exiting completely

from vessel.

Perform the following steps to install the liquid discharge device on a

vessel:

1. Attach the discharge device spout to the liquid discharge device (refer

to Figure 1 for location). A transfer line can be used in place of the

discharge device spout.

2. Verify that the rubber stopper is dry and free from grease and other

contaminants. Check for nicks and gouges that may impair normal

operation.

3. Verify that the cable is in good working condition.

4. Verify that the vent anddischargevalves turnfreely.

5. Loosen wingnut.

6. Lower discharge device into vessel. As the discharge device is lowered,

the nitrogen in the vessel will boil until the diptube has cooled down.

The boiling action is normal. Continue lowering until the rubber

stopper fits snugly.

Operation

7. Tighten the wingnut until it contacts the washer. Tighten wingnut

another 1½ to 2 turns (EXT RBR versions 4-5 turns).

Caution Tighten the wingnut finger-tight only, do not use any tools.

Tightening the wingnut expands the rubber stopper against the necktube

of the vessel. Excessive tightening may damage the necktube. s

8. Clip the safety cable to the vessel handle.

9. Close the vent valve and the discharge valve. Pressurewill slowly begin

to build. Several hours will be required to achieve sufficient pressure to

operate the liquid discharge device. Pressure buildup can be accelerated

by gently tipping the vessel at 45°angle.

Caution Excessive pressure can rupture the vessel. s

Installation (continued)

Figure 3-1. Components

Perform the following steps to withdraw liquid from the vessel using the

liquid discharge device:

1. Turn the discharge valve fully open and then turn back the valve a half

turn. Do not leave the valve in the fully open position.

2. Close the discharge valve to end liquid withdrawal.

Warning Cryogenic liquids are extremely cold and can cause sever burns

similar to frostbite. See CGA Bulletin No.P-12 Safe Handling of

Cryogenic Liquids. (This bulletin may be ordered from Compressed Gas

Ass’n., 4221 Walney Road, 5th floor, Chantilly, VA 20151.) s

Warning Nitrogen vapors in air may dilute the concentration of oxygen

necessary to support or sustain life. Exposure to such oxygen deficient

atmosphere can lead to unconsciousness and serious injury, including

death. s

Warning Modifying safety valves on discharge devices causes potentially

hazardous conditions. s

Perform the following steps to remove the liquid discharge device from the

vessel:

1. Open the vent valve to remove all pressure.

2. Verify that the pressure gauge reads 0.

Warning Vessel must be completely vented before removing the discharge

device. Any attempt to remove the discharge device before the vessel is

completely vented may result in serious personal injury. s

3. Release wingnut.

4. Rock discharge device from side to side to free stopper.

5. Pull discharge device from vessel.

6. When stopper has passed rim of vessel, unclip safety cable.

7. Store liquid discharge device in a clean and dry area.

8. Cover vessel.

Operation

Removal of Liquid

Discharge Device

Operation

The procedure below pertains to Thermo 5, 10, 20, and 30 vessels.

1. Use a wooden dipstick. Never use a hollow tube or plastic dipstick to

measure liquid nitrogen.

2. The liquid level will be indicated by a frostline which develops when

the dipstick is removed.

1. Liquid withdrawal for Thermo 5, 10, 20 and 30 is always performed

by pouring or utilizing a withdrawal device (for withdrawal devices, see

Parts List). The withdrawal device pressurizes to approximately 4 PSI;

the pressure forces liquid up the withdrawal tube and out the valve.

2. Always wear proper safety attire.

Warning Liquid nitrogen is extremely cold; it boils at -196°C. Extreme

caution should be exercised when handling cryogenic liquids. Always wear

proper safety attire when transferring liquid nitrogen into or out of

Thermo cylinders. Contact with a cryogenic liquid or cold gas may cause

frostbite to unprotected areas of the body. Protect eyes and skin when

transferring liquid. Stand clear of vent during filling. Loose fitting,

insulated gloves and long sleeves are recommended for arm protection.

Cuffless pants should be worn outside boots or overshoes to shed spilling

liquid. Goggles or face shields should be worn if the possibility of

splashing liquid exists. Failure to observe this warning may lead to severe

burns or eye injuries. s

To avoid damage to your dewar, it is important that only the two

following methods be used to fill your vessel. Failure to follow each step

may result in damage which is not covered under the warranty. Read all

instructions carefully. Should questions arise, contact Technical Services.

Liquid Withdrawal

Filling Instructions

(Thermo 8127)

The Thermo 8127 cylinders can be filled by removing the brass plug on

the top center of the tank and inserting a funnel through the hole. Liquid

nitrogen can then be poured directly into the cylinder through this hole.

Be sure to stand clear of the vent during filling and always wear proper

safety attire while handling liquid nitrogen.

1. Open vent valve completely, releasing any pressure built up inside the

cylinder.

2. Remove brass plug located on the top center of the cylinder.

3. Insert funnel into hole.

4. Pour liquid nitrogen into cylinder until level gauge reads 7/8 full or

until liquid nitrogen begins spitting from the vent valve.

5. Reinsert and tighten the brass plug.

6. Close vent valve completely.

The Thermo 8127 liquid nitrogen cylinders can be filled from a

pressurized source of liquid nitrogen by attaching a transfer hose to the

liquid withdrawal valve on the Thermo cylinders. The liquid nitrogen

source pressure must not exceed 45 PSI. Read all instructions carefully

before filling.

1. Attach transfer hose from liquid nitrogen source to the liquid

withdrawal valve on the Thermo cylinder.

2. Open withdrawal valve on Thermo cylinder completely.

3. Open withdrawal valve on liquid nitrogen source. Liquid nitrogen

source pressure must not exceed 45 PSI, since damage to Thermo

cylinder gauges will occur. Optimum feed pressure is 35 PSI.

4. Open vent valve on Thermo cylinder until the pressure gauge on

Thermo cylinder reads 22 PSI.

5. Continue to fill until Thermo cylinder weight is 180 pounds for the

8127. If the scale method is not possible, fill until liquid nitrogen

begins spurting from vent valve.

6. Shut liquid nitrogen source valve completely.

7. Shut liquid nitrogen withdral valve on Thermo cylinder completely.

8. Carefully remove transfer hose from the Thermo cylinder. Some liquid

nitrogen will remain in the hose under pressure after filling

9. Close vent valve completely.

Operation

Funnel Filling Method

Low Pressure LN2 Supply

Filling Method (8127)

Caution Overfilling cylinders may result in damage to the level and

pressure gauges. If overfilling should occur, remove excess liquid nitrogen

by opening the liquid nitrogen withdrawal valve immediately. s

Thermo 8127 are to be used only for low pressure liquid withdrawal.

The primary relief valve is factory set at 22 PSI. The secondary safety relief

is set at approximately 35 PSI. Transferring liquid at higher pressures

increases the flash-off rate of the liquid and adds to the risk of sparking.

To transfer liquid, attach the transfer hose or withdrawal spout to the

liquid connections (see accessory sheet). Slowly open the liquid valve to

flow the liquid. The liquid will vaporize at first until the transfer line or

withdrawal valve cools down. If using a transfer hose to extract liquid from

the Thermo 8127 into an open dewar, a phase separator is recommended

on the end of the transfer line.

Transfer pressure should be kept to a minimum. The normal evaporation

of the liquid will usually maintain enough pressure for transferring.

Caution If the liquid or vent valves are not closed, the container can

become contaminated after being emptied. s
