Beginning September 18, 2026, STORE will no longer sell compressed gas cylinders. Please review the information on this page for important updates and resources regarding this transition.

Important Update

Due to campus-wide budget constraints, UC San Diego has phased out STORE and its campus-managed fulfillment model. The STORE Gas Cylinder Program has officially ended. All gas cylinder purchasing and delivery will now be fulfilled directly by contracted suppliers as of September 18, 2026.

Airgas and Nippon Sanso Matheson gas products are now available through Advanced Search in Oracle, where clients will continue to have access to UC-negotiated pricing.

We sincerely thank our clients for their business, partnership, and trust throughout the years. It has been our privilege to serve campus.

  • Checkout Address: Select the delivery address ending in "-Direct" that corresponds to your specific delivery location during Oracle checkout.
  • Account Setup: Suppliers may contact you after your initial order to set up your direct customer account.
  • Supplier Communications: You will receive order, delivery, and account updates directly from Airgas and Nippon Sanso Matheson. These outreach communications are legitimate and expected as suppliers manage fulfillment directly.

Delivery & Cylinder Pickups

Frequently Asked Questions

Program Transition FAQs

Why is the gas cylinder program changing?

The gas cylinder program is changing to streamline operations and reduce administrative costs.

When will this change be effective?

STORE will no longer sell compressed gases beginning September 18, 2026. The last day to place an order with STORE is September 17 , 2026. 

Who will manage gas cylinders now?

Beginning August 31, 2026, compressed gas suppliers such as Airgas and Nippon-Sanso Matheson will begin delivering to campus departments and labs directly. Each supplier will be responsible for the entire gas cylinder life-cycle from purchase order to collection of empties. STORE will continue to fulfill orders through September 18, 2026.

General FAQs

How do I order compressed gas cylinders?

Following the transition, please use the Advanced Search catalog to purchase compressed gases. If the gas you need is not available on this catalog, please contact the supplier for a quote and submit a Quantity Based Form, found under Requisition Forms in Oracle Procurement.

When can I expect my gas cylinders to be delivered?

Stock gases, available on the Advanced Search catalog, are typically delivered within 1-3 business days upon requisition approval. However, in rare cases, supplier manufacturing delays may temporarily deplete inventory. These delays are usually resolved within a few business days, and orders are fulfilled in the order they were received once stock is replenished.

Specialty gas lead times are dependent on the supplier's ability to produce and deliver the product and can vary from 3-5 business days to 2-3 months. In rare cases, lead times may exceed 3 months.

How do I return a cylinder that is empty or no longer needed?

Simply mark the cylinder as "empty" or "for pickup" and leave it in your designated delivery area. The driver will collect these cylinders during your next delivery. If you do not plan on ordering replacement cylinders, please contact the appropriate supplier directly.

Will the suppliers charge a cylinder rental/demurrage fee?

No. We have partnered with our suppliers to provide bundled pricing so there is no longer any recurring monthly rental costs for gas cylinders.

Can the suppliers fill customer owned cylinders (COCs)?

No. Our gas vendors no longer fill customer owned cylinders (COCs). Requests to refill COCs can no longer be accommodated.
