Facilities - Cryogenics


Cryogenics Dr. Parashu Kharel

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.)
