UNC-Chapel Hill Vendor for Dry Ice and Gases
Airgas/National Welders is UNC-Chapel Hill’s eProcurement vendor for the purchase of liquid nitrogen, dry ice*, and cylinder gases. All gas cylinders have an accompanying cylinder rental fee called demurrage. It is therefore important to have empty cylinders picked up as soon as they are empty to reduce total rental costs.
For details on ordering, see the Gas and Dry Ice page.
