Gas Services

ASU Gas Services sells and distributes compressed gases, liquid nitrogen and dry ice to ASU’s research, scientific and academic communities. We also rent dewars and cylinders to the ASU community for the transportation and storage of compressed gases and liquid nitrogen. Our gas cylinders are available for delivery to all ASU campuses, and our dry ice and liquid nitrogen are available for self-service pickup on the Tempe campus. Years of experience, low prices, and high-tech solutions allow us to provide unparalleled customer service. Visit Gas Services information for additional details.

How do I order gases?

How do I order inventory gases or parts?

All orders should be placed directly in FMS.

To order inventoried gas, create a requisition for Goods and Services, click on search catalog, and then type in the name of the gas you would like to order.

A limited selection of regulators are available in inventory. To order a regulator, create a requisition for Goods and Services in FMS, click on search catalog, and then search the catalog for regulators.

How do I order or obtain a quote for special order gases or parts?

To order a specialty gas, you will need to create a requestion for specialty gas, non-catalog item in FMS.

To obtain a price quote for non-catalog gas or part, complete the non-catalog requisition within FMS.

How do I order a Liquid Nitrogen dewar refill?

Within FMS, create a requisition for Goods and Services, click on search catalog, and then type in LN2 Dewar Fill. Refills will be completed within two business days from receipt of the fully approved order.

When will my cylinder be delivered?

For inventoried cylinders, approved orders for Tempe, West and Downtown Phoenix campuses are delivered within three business days. Polytechnic campus deliveries are on Friday each week. 

Cylinders requiring faster delivery may be assessed a rush charge. Same day delivery is not available at this time.

When a cylinder is delivered to a cylinder cage, an email will be sent to notify you the cylinder has been delivered. No storage is allowed at any of the cylinder cages and all cylinders must be removed within three business days.

Please verify the delivery address when you place your order in FMS. All cylinders that need to be redelivered due to an incorrect recipient address will be assessed a $75 redelivery fee.

How do I return cylinders?

If your cylinders are delivered to a cage, then the empty cylinders can be placed back into that cage. Be sure to remove the full portion of the tag on your empty cylinder before placing it in the cage. Cages are monitored on a weekly basis and will be collected by Gas Services. No additional notification is needed.

If you receive cylinders directly to your lab, send an email to Gas Services to request a pick-up within two to three days.

Liquid nitrogen

Liquid Nitrogen, or LN2, is available to authorized ASU researchers, professors and authorized students. ASU Gas Services provides LN2 through an automated dispensary system located on the east side of the Physical Science, G wing. This automated system is available 24 hours a day, 7 days a week for users with key access.

To receive access to the Liquid Nitrogen system:

  1. Access the FMS.

  2. Create a Goods and Services Requisition.

  3. Click on search catalog.

  4. Type in LN2 Access Card on the search field.

  5. Add the card to your cart and check out.

LN2 access cards are not transferable and are renewed annually.  

In addition to applying for the access card, a mandatory EHS Fill Station Safety Course will need to be completed successfully annually. Search the Blackboard course catalog for Liquid Nitrogen.

Once the card is approved in FMS and the EHS Fill Station Safety Course is completed, you will be notified and will receive your LN2 access card.
