Connect the liquid nitrogen withdrawal device to storage dewars 03773-01, -02, or -03 to dispense liquid nitrogen. Withdrawal device clamps directly onto the special neck flange of the dewars—no other tools required. Use the withdrawal device to transfer liquid nitrogen at rates up to 8 L/min at 7.25 psi. Dispense liquid nitrogen directly from the device using the provided spout or through a standard cryogenic hose connected to the outlet. Uniquely designed device allows filling of the storage dewar without removing the device or venting system pressure.
