Accessory - Liquid withdrawal device for 25, 35 and 50 LD/LDB Dewars

The Liquid Withdrawal Device (LWD) provides convenient pressure transfers of liquid nitrogen from 25, 35 and 50 LD/LDB 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 6.5 psig (0.45 bar/45 kPa). Liquid can be dispensed directly from the LWD via the spout provided, or through a standard cryogenic hose connected to the liquid outlet.
