High nitrogen purity: PSA nitrogen generator plants allow production of high-purity nitrogen from air, which membrane systems are unable to provide up to 99.9995% nitrogen. But in most cases they do not produce more than 98.8% nitrogen with the remainder being argon that is not separated from the nitrogen by the usual PSA process.
Standard Operating Procedure for Filling a Liquid Nitrogen Dewar (specific for the equipment in Chemistry) Note: When filling a liquid nitrogen (LN2) Dewar, the doors must be open at all times to prevent asphyxiation from the gas displacing the oxygen in the room.

Recirculating Liquid Nitrogen System for Operation of Cryogenic Pumps IEPC-2011-217 Presented at the 32 nd International Electric Propulsion Conference, Wiesbaden Germany September 11-15, 2011 Alexander W. Kieckhafer * and Mitchell L. R. Walker † Georgia Institute of
Liquid nitrogen is a diatomic liquid, which means that the diatomic character of the covalent N bonding in N 2 gas is retained after liquefaction. The temperature of liquid nitrogen can readily be reduced to its freezing point 63 K (−210 °C; −346 °F) by placing it in a vacuum chamber pumped by a vacuum pump.
Our StirLIN products (see below) consist of a wide range of liquid nitrogen liquefiers producing LN 2 in volumes from 3 up to a 50 liter per hour (70 to 3.600 liters per day). The liquid nitrogen generation plants are a popular, plug and produce solution.

litre of liquid nitrogen will produce 0.7m 3 of gas). Nitrogen gas is invisible the cloudy vapour which appears when liquid nitrogen is exposed to air is condensed moisture, not the gas itself. Asphyxiation One of the main dangers associated with liquid nitrogen is the risk of asphyxiation when used or stored in poorly ventilated areas.
Liquid nitrogen (Ln2) loss reduction at testing operation Abstract: The cold testing is performed at test area. Normally, portable liquid cylinders (PLC) are used to supply liquid nitrogen (Ln2) to test handlers. One full PLC of Ln2 will normally last up to 6 to 8 hours of production.
Cyl-Tec cryogenic liquid cylinders are designed to transport, store and dispense liquid oxygen, nitrogen, argon, carbon dioxide, and nitrous oxide. The HP series cylinders are factory set to automatically maintain a normal operating pressure between 300 and 315psig (2.07-2.17Mpa), with the
