LIQUID

WITHDRAWAL DEVICE

For Liquid Nitrogen

LD25, LD35, and

50LD Dewars

TW-43

The Liquid Withdrawal Device (LWD) provides convenient

pressure transfer to liquid nitrogen from LD25,LD35, and

50LD Dewars. The device clamps directly to the special

neck flange that is found under the plastic trim collar

around the neck of these containers.

Flow rates up to 8 liters per minutes are possible at

operating pressures up to 10 psig (0.7 bar/69 kPa). Liquid

can be dispensed directly from the LWD via the spout

provided, or through a standard cryogenic hose connected

to the liquid outlet.

Filling a Dewar is accomplished by pressure transfer

through the withdrawal device. (See Filling Instruc-

tions.) This filling method allows replenishment of the

liquid supply in the Dewar without removing the LWD,

while keeping the liquid saturated at a pressure sufficient

to sustain liquid withdrawal.

Before using this equipment, read these instructions

carefully. Also, read and understand the instructions sup-

plied with your Dewar and the Handle with Care booklet

packed with all Liquid Nitrogen Dewars. The Handle with

Care booklet (Form TW-10) gives detailed information on

the safe handling of liquid nitrogen. Additional copies of

these publications can be obtained from your supplier. Do

not modify LWD or Dewar or use in a manner other than that

described in accompanying instructions and documentation.

Contact with liquid nitrogen or cold gas may cause

serious freezing (frostbite) injury. Do not touch liquid or

cold metal surfaces with your bare skin. Always wear a face

shield and gloves when transferring liquid nitrogen.

Nitrogen gas can cause suffocation without warning.

In a confined area, nitrogen gas from this equipment may

displace air required for breathing. Store and use this

equipment only in well-ventilated areas.

Use only containers designed for low-temperature

liquids. Cryogenic containers should be filled SLOWLY to

minimize stresses which can damage the container.

Vent all pressure from a Dewar before attempting to

remove the Liquid Withdrawal Device. If the band clamp

securing the LWD to a dewar is loosened while there is

pressure in the Dewar, cold gas or liquid could be expelled

causing personal injury.

Liquid Withdrawal Device is for use with liquid nitrogen

only. LWD is for use on specific model Taylor-Wharton

Dewars listed above.

Pressure in Dewar with LWD installed should never

exceed 10 psi. Fill dewar from supply source at 22 psi or

less. Do not pressurize using compressed air.
