Liquid Withdrawal Device (LWD)

For convenient, pressurized dispensing of liquid nitrogen

The Liquid Withdrawal Device (LWD) provides convenient pressure transfers of liquid nitrogen from 25LD, 35LD 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 7.25 psig (0.5 bar/50 kPa).

Liquid can be dispensed directly from the LWD via the spout provided, or through a standard cryogenic hose connected to the liquid outlet.
