Liquid Nitrogen Withdrawal Device

The Worthington Industries Liquid Withdrawal Device is designed to provide the safe and convenient pressure transfer of liquid nitrogen (LN2) from the LD25, LD35 and LD50 dewars.

The Liquid Withdrawal Device clamps directly on to a specially-designed neck flange for easy installation. Liquid is directly dispensed at rates up to 8 liters per minute through the Liquid Withdrawal Device spout provided, or through a standard cryogenic hose connected to the liquid outlet.

Liquid Withdrawal Device Features:

  • Fast, safe and convenient to fill
  • Ready for immediate use after filling
  • Two pressure relief devices
  • Reduces risk of damage to dewars
  • Safe handling of LN2

Dewars are filled by pressure transfer through the withdrawal device, which maintains a saturated pressure and allows for the replenishment of the liquid supply in the dewar without removing the device.
