Gas Services

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 want to order.

Cylinders requiring faster delivery will be assessed a rush charge. Rush charge pricing begins at $75.00. Travel time and additional fees will be applied to large orders.

The requesting department must continue paying the monthly rental fee until the return is recorded. The requesting department will incur the total replacement cost if a cylinder or dewar is lost or stolen. 

ASU Gas Services must be notified when a cylinder or dewar is transferred to another user or if a lab or account number changes. 

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 obtain a quote for special order gases or parts?

To order a specialty gas, you must create a requisition for specialty gas, a non-catalog item in FMS.

Complete the non-catalog requisition within FMS to obtain a price quote for non-catalog gas or part.

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.

Dewars requiring faster delivery will be assessed as a rush charge. Rush charge shipping begins at $75.00. Travel time and additional fees will be applied to large orders. 

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 will be assessed as a rush charge. Rush charge shipping begins at $75.00. Travel time and additional fees will be applied to large orders

When a cylinder is delivered to a cylinder cage, an email will be sent to notify the requester 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 re-delivery fee.

How do I return cylinders?

If your cylinders are delivered to a cage, the empty cylinders can be placed back in. Remove the entire portion of the tag on your empty cylinder before putting it in the cage. Cages are monitored every week, and Gas Services will collect cylinders. 

The Department of Transportation requires all cylinders to have an appropriate-sized cap for transportation. Please contact Gas Services if you need to purchase a replacement cap for your cylinder. 

If you receive cylinders directly to your lab, email Gas Services to request a pickup 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 on the east side of the Physical Science G wing. This automated system is available 24 hours a day, seven 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 must be completed annually. 

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.

Cage access

Many buildings have cylinder cages and rooms, which allows Gas Services to have a central delivery point for that building. Only authorized, certified Gas Services customers are allowed to access these locations. You will need a key to access the following rooms or cages:

You will need to complete the critical action form to obtain a key. Enter your direct supervisor’s name and the location and room information above to complete the form.

Dry ice

Dry ice is available 24/7, with crucial access requirements, at Physical Science, G wing, room G101. There is a scale located by the dry ice coolers to accurately record the amount dispensed in the log located by the coolers:

• Date
• Principle Investigator/Department
• Cost Center
• Program, grant, gift, or project number
• Weight of the dry ice being dispensed
• Your name

Warning: Dry ice is stored at -109 degrees Fahrenheit. Do not handle it with your bare hands, as it can cause serious injury. Personal protective equipment is available at the dispensing station.
