About the company
Rotunda Scientific Technologies LLC, doing business as Rotunda SCI TECH, is a woman-owned small business headquartered in Mansfield, Ohio, that manufactures and maintains radiation detection and luminescence analysis equipment for federal agencies as a prime contractor on nearly all of its federal work (96% of awards). The company operates as a limited liability partnership structured as a Subchapter S Corporation and competes predominantly under total small business set-aside procurement, with primary NAICS categories in Other Measuring and Controlling Device Manufacturing (11 awards) and Analytical Laboratory Instrument Manufacturing (5 awards).
Rotunda's federal capability portfolio centers on the sale and maintenance of specialized scientific instrumentation for radiation detection, dosimetry, and luminescence analysis. Representative prime work includes a $738 thousand firm fixed-price purchase order from Naval Sea Systems Command (awarded March 2022, completed September 2024) for accident dosimeters, attachment caps, opening tools, and training supporting the Radiation Detection Technology Branch at Naval Surface Warfare Center Carderock Division; a $150 thousand small-business-set-aside maintenance contract with the U.S. Geological Survey (awarded September 2024, running through March 2030) for Lexsyg luminescence readers at the USGS Luminescence Geochronology Laboratory in Denver, Colorado; and a $137 thousand purchase order from the Department of Agriculture's Agricultural Research Service (awarded September 2026, completing March 2027) for a Bruker Minispec mq20 nuclear magnetic resonance analyzer for the National Center for Agricultural Utilization Research in Peoria, Illinois.
Customer concentration is heavily weighted to the Department of the Navy, which accounts for 9 of the top-five customer agencies' combined awards and $1.2 million (44% of total potential value). The top five customer agencies by count represent 67% of awards; by potential value, the top five (Naval Sea Systems Command, Air Force Materiel Command, USGS, Defense Finance and Accounting Service, and Army Materiel Command) represent 82% of combined potential value, surfacing concentration in defense and interior research agencies. Rotunda has served 14 distinct customer agencies over its award history.
Activity over the last five years shows decline from four awards in 2022 to one in 2024, with a recent uptick to three awards in 2026. Three awards carrying combined potential value of $361 thousand face ultimate completion within the next twenty-four months and present recompete opportunity. The vendor subcontracts minimally — one sub-award visible in the source (January 2026) with Axle Informatics on animal model development and efficacy testing of medical countermeasures. Rotunda's combined potential value across all 27 federal awards in the source is $2.7 million, with 94% obligated, reflecting a small-scale, transaction-heavy federal footprint anchored in single purchase orders rather than IDIQs or multi-year vehicles.
