M001 50 LD LN2 Dewar

Maker: Taylor Wharton made in USA
Liquid Nitrogen Dewar - Model 50LD

50 litre capacity.

This unit is fitted with a Liquid Withdrawal Device.

From the manufacturers - Taylor Wharton -
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 Instructions.)
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
