Beryllium Windows - SEE DESCRIPTION (G5-224031)

The Department of Energy Office of Science, through Argonne National Laboratory, is procuring 2 beryllium windows with highly specific technical requirements including 200um thickness, integration into 2.75" conflat flanges, a minimum 35mm clear aperture, and surface roughness of 0.8um Ra or better. This specialized laboratory equipment procurement requires vendors to complete comprehensive documentation including the ANL-70A Representations and Certifications form, with all sections A-F on page 2 mandatory for consideration. Quotations must include country of origin, shipping costs, lead time, signed documentation, and pricing details, while adhering to Buy American requirements mandating that U.S. components exceed 65% of total component costs for 2024-2028 deliveries. The original submission deadline was September 2, 2025, at 11:30 PM CST, but Addendum 1 extended the solicitation expiration to September 8, 2025, at 12:00 PM CST. All inquiries should be directed to Annette Wegrzyn at awegrzyn@anl.gov, and incomplete submissions will be discarded.

This procurement does not utilize any set-aside designations and no incumbent contractors are identified in the solicitation materials. While no specific contract value or budget range is disclosed, the highly specialized nature of beryllium windows with precise technical specifications suggests a niche, high-value procurement. The quantity is limited to 2 units, indicating this is likely for specific research or laboratory applications rather than bulk procurement. Performance will take place in Lemont, Illinois 60439, at the Argonne National Laboratory facility. The procurement includes comprehensive safety documentation regarding beryllium handling, including Material Safety Data Sheets and DOE Chronic Beryllium Disease Prevention Program regulations, reflecting the hazardous nature of the material and strict regulatory compliance requirements. Payment terms are established as net 30 days with F.O.B. destination shipping.
