Columbus Instruments, LLC

Columbus Instruments, LLC, a self-certified small disadvantaged business based in Columbus, Ohio, manufactures specialized laboratory animal monitoring and metabolic research instrumentation as a prime contractor, selling respirometry systems, comprehensive lab animal monitoring (CLAMS) equipment, exercise treadmills, and related sensors and components to federal research agencies under full-and-open (non-set-aside) purchase orders. The company holds no parent contract vehicles, IDIQs, or GWACs and operates entirely on individual firm fixed-price purchase orders.

Columbus Instruments is a limited liability partnership that competes without formal SBA set-aside designation on most awards, though a minority of recent work carries Total Small Business set-aside status. The vendor's footprint spans 26 prime awards worth $2.5 million in combined potential value across 14 distinct federal customer agencies, with 98% of that value obligated. Activity has grown unevenly — six awards in 2022, four in 2023, nine in 2024, then a sharp contraction to two awards in 2025 and four in 2026 — suggesting cyclical procurement patterns typical of federal research equipment buying.

Customer concentration clusters around civilian research agencies. The Department of Agriculture's Agricultural Research Service Pacific West Area leads by award count with seven purchase orders ($471 thousand combined potential value), driven by Micro-Oxymax respirometer system sales and expansions at the Bioproducts Research Unit in Albany, California. The National Institutes of Health accounts for substantial dollar volume through the National Institute of Diabetes and Digestive and Kidney Diseases ($572 thousand single award for a comprehensive lab animal monitoring system in 2026), the National Institute of Environmental Health Sciences ($408 thousand across two awards for CLAMS-HC enclosures and exercise treadmills), and the National Heart Lung and Blood Institute ($217 thousand across four awards for equipment maintenance and calibration services). The Department of Veterans Affairs Veterans Integrated Service Network 21 has placed two awards ($122 thousand) for CLAMS hardware maintenance in Palo Alto, and the Army Corps of Engineers' Engineer Research and Development Center has purchased two Micro-Oxymax systems ($247 thousand).

Representative capability work includes a $571,794.50 purchase order from the National Institute of Diabetes and Digestive and Kidney Diseases in June 2026 for a comprehensive lab animal monitoring system; a $391,351.25 purchase order from the National Institute of Environmental Health Sciences in September 2024 for CLAMS-HC ENC77 temperature and light controlled enclosures; and a $177,694.00 award from the Department of Agriculture in December 2021 for metabolic sampling hardware upgrades to a CLAMS unit. Product offerings concentrate in NAICS 334516 (Analytical Laboratory Instrument Manufacturing), with 22 awards classified there; maintenance and repair work accounts for five awards under related codes.

Only two awards ($248 thousand combined potential value) carry ultimate completion dates within the next twenty-four months, creating minimal near-term recompete exposure. Columbus Instruments holds no subcontracting relationships in the source data; all work is performed as a prime contractor, with service and installation delivered at customer sites (Columbus, Ohio; Palo Alto, California; Stratford, Wisconsin; Albany, California; Research Triangle Park, North Carolina, and other research facilities).
