Microfluidic Flow Model Fabrication

The contract requires the fabrication of optically transparent flow models that precisely replicate 22-Gauge and 25-Gauge micronozzle tips and extensions, available either at full scale or scaled up between four and ten times their original size. These models must meet stringent dimensional accuracy standards of ±1% and achieve a surface finish finer than Ra 0.6 µm to ensure reliable fluid dynamics testing under controlled conditions. The optical transparency is essential for visual and imaging-based analysis during experiments, and the precision in geometry and surface quality ensures the validity and reproducibility of test results. This subcontract is issued under a Total Small Business Set-Aside, with the NAICS code 334510 indicating a focus on semiconductor and other electronic component manufacturing. The opportunity is managed by the FDA Negotiated Contracts Branch within the Department of Health and Human Services, with performance required at Silver Spring, Maryland, 20993. The solicitation was posted on July 22, 2026, and proposals must be submitted by 6:30 PM EDT on July 31, 2026. The contract is targeted exclusively at qualified small business entities, and all deliverables must align with the technical specifications to support critical biomedical fluid flow research.
