Important Notice:  Due to the increased demand from the entire University a limited supply of Dewars (containers) from Praxair, Central Stores can no longer guarantee next day delivery for Liquid Nitrogen.

Individual orders will be processed on a first come first serve basis.  Praxair suggests 2-3 day turn around.

Please adjust your ordering schedule and usages accordingly.

Recurring orders will be processed on their specific days as per Praxair standards. 

Central Stores has implemented a consolidated program for the ordering, delivering and pick up of compressed gas cylinders, Dewars and associated materials throughout campus.  The goal of the program is to promote safety and safe handling of cylinders, and to provide a consistent and dedicated order/delivery process for compressed gases.  Benefits of this program include improved inventory control, cost savings via a centralized drop location, reduced surplus of cylinders on campus, and safe delivery to and from end user locations.

All gases will be supplied by Praxair the University’s preferred supplier. Air Liquide has a specific contract for Helium and some specialty gases.  For other vendors (Linde) and specialty mixtures not supplied by either of these companies, please contact us first for a quote.

To order new cylinders, or to schedule a pick-up of used cylinders click on the Gas Cylinder Order Form tab on the left.

Make sure to fill in all required fields for proper billing information and delivery scheduling.

Central Stores will contact you to schedule a delivery time and is NOT responsible for installing or removing any regulators for the requested cylinders.  As well, special arrangements need to be made for clean room deliveries.
