Xenon Gas Purchase

The U.S. National Aeronautics and Space Administration, through the NASA Shared Services Center, is seeking to procure approximately 5,000 liters of high-purity xenon gas with a minimum purity of 99.999% for use in electric propulsion testing, under a firm-fixed-price contract set aside exclusively for small businesses as defined under FAR 19.5. The procurement, identified by solicitation number 80NSSC26933373Q, is being conducted under NAICS code 325120, and delivery must be made to Cleveland, Ohio 44135, with freight terms specified as F.O.B. destination, meaning the vendor is responsible for all shipping costs including delivery to both NASA-supplied cylinders and new vendor-provided cylinders. The xenon must be packaged in cylinders with a minimum of one year remaining on their DOT certification, equipped with rare gas or bellows-sealed valves and CGA 580 fittings, and each cylinder must be accompanied by a Certificate of Analysis detailing the precise quantity in liters at standard temperature and pressure (32°F and 29.92 inHg), actual measured impurity levels, and measurement uncertainty for each contaminant, with total impurities not exceeding 10.4 ppm and strict limits on individual contaminants such as oxygen, water, carbon monoxide, and krypton. The contract requires strict compliance with hazardous materials handling protocols, including submission of Material Safety Data Sheets consistent with 29 CFR 1910.1200(g) and Federal Standard No. 313, with copies included on every shipment container and in the packing list for consignees. The evaluation is based on a lowest price technically acceptable model, where technical acceptability is a pass/fail gate; offers must satisfy all requirements in the Statement of Work, provide sufficient manufacturer literature and technical documentation, and submit the MSDS prior to award to remain eligible. Offerors must be registered in SAM.gov, include their CAGE code, FOB destination, and lead time on their bid, and provide two points of contact. All proposals must be submitted via email to Cara Craft at cara.s.craft@nasa.gov by 1 p.m. Central Time on June 30, 2026, and must remain valid for 30 days. The contractor is also subject to specific FAR clauses including those on personal identity verification, sustainable products, DEI
