Cryogenics provides the means for obtaining Liquid Nitrogen and Liquid Helium for low temperature research, cold traps, etc.
Liquid Nitrogen:
A 230 liter supply of liquid Nitrogen is maintained at this facility. Researchers can transfer LN2 to their own dewars (typically 1-30 L) as needed and are billed on a per liter basis.
Liquid Helium:
LHe orders are delivered to UNL only once a week (Tuesdays), and orders must be submitted to the specialist by the previous Thursday to ensure that the request is placed in time. A delivery location (building and room#) should be specified. LHe can be ordered in 60 or 100 liter containers.
Emergency deliveries of LHe (available with ~ 2 days notice) are available, but are subject to a special freight charge. (This charge is about $150 - $200!!)
