Notice of Intent to Sole Source to Isotropx

The DOE Idaho Operations Office is intent on a sole‑source, firm‑fixed‑price purchase of one Isotopx DG60 Filament Degasser (product code 90009326) for the Radiological and Environmental Sciences Laboratory’s Phoenix TIMS system. The DG60 performs automated vacuum‑thermal routines to remove uranium interference from rhenium filaments used in ultra‑low‑level plutonium isotopic measurements. The award will include the degasser unit, proprietary control software, filament racks, on‑site engineer installation, training, and a minimum 24‑month manufacturer warranty, delivered DDP to Idaho Falls, ID. Because the DG60 is a proprietary peripheral that physically and electronically integrates only with Isotopx’s TIMS, the government is not seeking competitive proposals but will accept capability statements from qualified small businesses that can demonstrate identical technical compatibility and OEM authorization. • One (1) Isotopx DG60 Filament Degasser (firm‑fixed‑price) • Must integrate with existing Isotopx Phoenix TIMS (hardware & software) • Includes installation, training, and 24‑month warranty • Delivery Duty Paid to RESL, Idaho Falls, ID • Capability statements due September 28 2026; no phone inquiries accepted • Sole‑source justification based on system integration, isobaric‑interference mitigation, and proprietary rights.
