UHV Viewport Assembly with Manual Shutter

Oak Ridge National Laboratory (ORNL), operated by UT‑Battelle, is seeking proposals for an ultra‑high‑vacuum (UHV) viewport assembly with manual shutter, or domestic equivalents, to support a DOE‑funded project. The solicitation is a firm‑fixed‑price RFQ (lowest‑priced technically acceptable award) for 20 units of a zero‑length 4‑½″ viewport with lead‑glass disk and matching manual shutter. Vendors must submit a price quote, delivery schedule, and the required representations & certifications. The contract will be awarded to the lowest‑priced, technically acceptable offer; no small‑business set‑aside applies. • Provide 20 UHV viewports (4½″) with manual shutters, meeting the specifications in the Bill of Materials (Kurt J. Lesker part numbers VPZL‑450XLG and DS450VPS). • Submit a firm‑fixed‑price quote valid for 120 days, along with required certifications (Buy‑American, export‑control, telecom prohibitions, etc.). • Key deadlines: questions due 11 / 04 / 2026, proposal due 11 / 06 / 2026 (5 PM EDT).
