Sole Source Request to Purchase X‑Ray Tube, 2.2 kW, Cu, Ceramic, LFF, Canon, and Corrosion Inhibitor (BTA), 10 mL

Mississippi State University is issuing a sole‑source procurement for a specialized 2.2 kW copper‑ceramic LFF X‑ray tube and a 10 mL corrosion inhibitor (BTA) to replace the tube in its Rigaku SmartLab X‑ray diffractometer. The university determined that only Rigaku Americas Corporation can supply the exact, manufacturer‑specific component required for compatibility, performance, and safety. After contacting Canon Medical Components USA and confirming they could not provide the part, the university obtained a price quote of $9,872.70 from Rigaku. The solicitation allows objections; any party believing an alternate source exists must submit a written notice to the Director of Procurement Services. • Item: X‑Ray Tube, 2.2 kW, Cu, Ceramic, LFF (Rigaku SmartLab) + 10 mL BTA corrosion inhibitor • Supplier: Rigaku Americas Corporation (sole source) • Estimated cost: $9,872.70 • Purchase type: Sole‑source, “Request for Information” posting • Submission deadline: February 11, 2026 • Objection process: Written notice to Jennifer Mayfield ([email protected]) • No pre‑bid meeting or site visit required.
