About the company
Structure Probe Inc., doing business as SPI Supplies, is a for-profit manufacturer of specialized laboratory equipment and supplies based in West Chester, Pennsylvania, operating as a prime contractor (98% of recent awards) on non-set-aside federal purchase orders across defense, civilian research, and health agencies. The vendor competes full-and-open, with no recurring set-aside posture; its single small-business set-aside award was issued by the CDC in 2023.
SPI Supplies manufactures analytical laboratory instrumentation for electron microscopy, materials testing, and sample preparation. The vendor's capability portfolio centers on scanning electron microscopy (SEM) and transmission electron microscopy (TEM) equipment, sputter coaters, reactive ion etch systems, micro-fatigue loading systems, and supporting laboratory supplies and fixtures. Representative recent work includes a $122,900 firm fixed price purchase order from the Office of Naval Research (awarded December 11, 2025, for a micro-fatigue loading system with delivery to Washington, DC), a $44,620 purchase order from the Army Research Laboratory (June 27, 2024, for a turbo-pumped benchtop reactive ion etch system), and a $15,555.65 total small business set-aside purchase order from the CDC Pittsburgh (June 20, 2023, for a sputter coater).
Customer concentration is scattered across 24 distinct federal agencies, with no single agency dominating either award count or potential value. The Department of the Navy Naval Sea Systems Command leads by award count (7 awards), while the Office of Naval Research anchors the potential-value ranking (3 awards, $147 thousand combined potential value). The CDC Pittsburgh, Army Materiel Command Research Development and Engineering Command, and the Environmental Protection Agency round out the top customers. Top NAICS concentrations are analytical laboratory instrument manufacturing (21 awards) and petroleum lubricating oil and grease manufacturing (3 awards); the primary PSC is laboratory equipment and supplies (40 awards).
Activity volume is low and flat — one award per year in 2020, 2021, 2023, and 2025, and two awards in 2024. Combined potential value across all 62 awards in the source data is $540 thousand, though combined obligated dollars ($730 thousand) exceed that ceiling, indicating delivery completions that drew down reserve funding. The vendor maintains a single subcontract relationship under Triad National Security, LLC, providing laboratory and scientific equipment and supplies to Los Alamos National Laboratory (sub award dated May 8, 2024). SPI Supplies seats on the Federal Supply Schedule GS24F1340C with one recorded task order.
