Chemistry Nitrogen Core Facility

Overview of Services


The Chemistry Nitrogen Core Facility operates out of Stepan Chemistry Hall room 149E. We offer both liquid nitrogen and piped nitrogen gas to users of our Core Facility. Turnaround times for filling large, wheeled dewars (180 – 240 L) is on average 50 min. A large, community dewar is available all year for dispensing liquid nitrogen into smaller (4 – 10 L), in-lab supplied dewars. Liquid nitrogen PPE is required for use of this community dewar. We thank you for choosing us for your research or instructional needs.
