X‑Ray Tube, 2.2 kW, Cu, Ceramic, LFF, Canon, and Corrosion Inhibitor (BTA), 10 mL

Mississippi State University’s Institute for Imaging and Analytical Technologies seeks to replace a proprietary X‑ray tube on its Rigaku SmartLab X‑ray diffractometer. The tube is a 2.2 kW, Cu‑ceramic, large‑format flat (LFF) component that can only be supplied by the original equipment manufacturer, Rigaku Americas Corporation. The university has already confirmed that an alternative vendor (Canon Medical Components USA) cannot provide the required part, making a sole‑source procurement necessary. The estimated purchase price is $9,872.70, and the acquisition must be completed by the October 14, 2026 deadline. • Replace a specialized, manufacturer‑specific X‑ray tube to restore diffractometer functionality. • Only qualified source is Rigaku Americas Corp; no competitive bids are permitted. • Procurement is valued under $10 K, requiring a sole‑source justification and an objection period overseen by the university’s procurement director.
