110 GHz Cryogenic Coax Cables and Feedthroughs

The National Institute of Standards and Technology (NIST), a civilian agency under the Department of Commerce, is soliciting quotations for 110 GHz cryogenic coaxial cables and feedthroughs to support bandwidth expansion of a dilution refrigerator system. The procurement requires firm-fixed-price quotations for four line items: 10 cryogenic-compatible coax cables with stainless-steel outer conductors, 2 superconducting niobium-titanium coaxial cables, 1 hermetic feedthrough with vacuum capability, and 4 non-hermetic feedthroughs for various temperature stages. Contractors must maintain active System for Award Management (SAM.gov) registration and submit quotations in three volumes covering technical capability, pricing, and terms and conditions. Award will be made to the lowest-priced, technically acceptable quotation based on demonstrated capability, country of origin, delivery confirmation, and warranty ability. The deadline for submitting quotations is April 6, 2026 at 2:00 PM Mountain Standard Time, with written questions due by March 25, 2026.

This is a total small business set-aside with a NAICS code of 334516 (Analytical Laboratory Instrument Manufacturing) and a small business size standard of 1,000 employees. No incumbent contractor is identified in the solicitation materials. The contract value is not explicitly stated, though the quotation structure suggests a relatively modest procurement scope. Delivery must be completed within 90 days after receipt of order to NIST-Boulder located at 325 Broadway, Boulder, Colorado 80305, with on-site inspection and acceptance expected to occur within 7 business days. Contractors should prepare quotations using a standardized 20-inch coax length for pricing purposes, with final specifications to be coordinated with the end-user's subject matter expert following contract award.
