AB Sciex LLC

AB Sciex LLC, a division of Danaher Corporation's Beckman Coulter subsidiary, supplies analytical instrumentation—mass spectrometers, liquid chromatography systems, chromatography accessories, and nitrogen generators—along with preventative maintenance, repair services, and software support to federal agencies as a prime contractor (99% of recent awards). The vendor operates exclusively in full-and-open competition with no SBA set-aside designations across its 1,052 total federal awards and holds significant standing relationships with civilian research and regulatory agencies through a $19.9 million Blanket Purchase Agreement with the FDA under the GSA Multiple Award Schedule (through April 2025) and a $2.503 million Indefinite Delivery Contract with the FDA for LC-MS/MS maintenance services (through April 2029).

AB Sciex LLC's customer concentration is split between two dominant federal agencies. The CDC Pittsburgh leads by potential value—122 awards worth $101.3 million combined—followed by the FDA at 159 awards worth $83.9 million. Together these two customers account for approximately 52% of the vendor's combined potential value across all awards. The Defense Health Agency, EPA Office of Research and Development, and the Army Medical Command round out the top five by dollars. The top five customers account for 46% of all recent awards. The two rankings track closely, indicating consistent order placement rather than a pattern of one large order anchoring a customer's dollar share.

Activity has been flat to slightly declining. The vendor recorded 46 awards in 2022, 55 in 2023, 49 in 2024, and 23 in 2025. Six awards have been placed through mid-2026. The 27 awards with ultimate completion dates in the next twenty-four months carry combined potential value of $6.8 million and represent near-term recompete exposure. Across SCI-reportable federal service contracts (a strict subset capturing only maintenance-related contracts above the $150,000 threshold), the vendor invoiced $3 million in FY2022 and $2.9 million in FY2024 with roughly 2.7 FTEs in each year; FY2023 SCI records show zero invoicing but carry two contracts. Government-paid hourly rates for maintenance labor run a median of $532.38/hr, with the 90th percentile reaching $1,389.63/hr. The vendor performs all work in-house—zero sub-hours share across prime SCI contracts—and does not sub to other primes in its federal business.

The vendor's contract portfolio clusters heavily in analytical laboratory instrument manufacturing (526 awards) and maintenance-repair work (371 awards). Task orders under the GSA Multiple Award Schedule dominate the vehicle footprint at 231 orders worth $154.5 million combined potential value. FDA-specific BPAs and IDCs generate supplemental order volume. AB Sciex LLC executes delivery orders, purchase orders, and blanket purchase agreement calls across 76 distinct federal agencies. Representative recent prime work includes a $3.29 million five-year maintenance contract with the Defense Health Agency for AB Sciex LC-MS/MS systems at Dover Air Force Base (awarded September 2024); a $1.652 million BPA call from the FDA for three triple-quadrupole mass spectrometers, three HPLC systems, and three nitrogen generators (September 2024); a $1.421 million maintenance services contract with the Defense Health Agency for LC-MS/MS systems at Aberdeen Proving Ground (September 2023); and a $6.433 million CDC delivery order for SCIEX instruments under the GSA MAS (September 2023). The vendor also subcontracts to Battelle Memorial Institute on an LC-MS/MS system procurement under a detection-canine-solutions LRBAA and acts as a sub-recipient to Indiana Department of Health on CDC Public Health Preparedness and FDA Laboratory Flexible Funding Model awards.

AB Sciex LLC competes full-and-open across civilian and defense agencies. The vendor holds no 8(a), HUBZone, SDVOSB, WOSB, or other SBA designations and is not minority-owned, women-owned, or disadvantaged. As a division of Danaher, a multi-billion-dollar diversified manufacturer headquartered in Washington, D.C., AB Sciex operates through parent Beckman Coulter (based in Brea, California) and serves the federal government primarily as a sole-source provider of proprietary mass spectrometry maintenance and equipment sales—a positioning that drives recurring non-competitive awards and pricing power but limits pipeline to agencies with existing AB Sciex installed bases or those seeking to establish them.
