This presolicitation notice announces the intent to award a firm-fixed-price sole-source purchase order to Bio Fire Defense, LLC for proprietary BioFire diagnostic assay kits and refurbished FilmArray 2.0 systems. The requirement supports NAMRU EURAFCENT's infectious disease surveillance and research operations. Delivery will be to NAS II Sigonella, Italy, no later than 15 calendar days after receipt of order. The sole-source justification cites proprietary consumables compatibility with existing platforms and a FOCI mitigation agreement restricting federal procurement to this authorized U.S. subsidiary. Interested parties may submit a capability statement demonstrating authorization, exact configuration, delivery, and warranty support, though this is not a request for competitive proposals.
