Seal Analytical Inc.

Seal Analytical Inc., a foreign-owned manufacturer of analytical laboratory instruments headquartered in Mequon, Wisconsin, sells discrete analyzers, continuous flow analyzers, ion chromatography systems, and digestion blocks to environmental and research agencies as a prime contractor on 162 small-dollar purchase orders, the vast majority under total small business set-asides.

Seal Analytical competes predominantly under small business set-asides — roughly 60% of recent awards carry total small business designations — across NAICS 334516 (Analytical Laboratory Instrument Manufacturing), its dominant classification. The company's product line centers on automated wet chemistry analyzers for water quality and nutrient analysis, including AQ300, AQ400, AQ700, and AA500 series discrete and continuous flow systems, along with specialized equipment such as DEENA digestion blocks, ion chromatography instruments, and chloride analyzers. Representative recent prime work includes a $112,914 EPA Region 4 delivery order for two AA500 HR analytical systems with installation and warranty (October 2025); a $97,720 USDA Agricultural Research Service award for a discrete analyzer at the National Laboratory for Agriculture and the Environment in Ames, Iowa (May 2024); and a $158,813 EPA Region 2 SNAP reverse auction buy for three ion chromatography systems (August 2023). The company also performs maintenance and support work — a $89,626 USGS contract for preventative maintenance on three autoanalyzer instruments runs through May 2031, and a $54,200 support and service agreement for AQ400 analyzer maintenance extends through October 2028.

Customer concentration sits with civilian research and environmental agencies. The Department of the Interior's U.S. Geological Survey leads by potential value (18 awards, $845 thousand combined), followed by the National Oceanic and Atmospheric Administration (15 awards, $586 thousand combined) and the Department of Agriculture's Agricultural Research Service across multiple field areas (31 awards combined, $527 thousand combined). These three agencies account for 49% of combined potential value. The Environmental Protection Agency, which spans multiple regional offices, places smaller orders across Regions 1, 2, 4, and 5 totaling 4 to 5 discrete awards per region. Across 162 total awards, Seal Analytical serves 32 distinct federal customer agencies, with no concentration on defense or classified work — the Defense Health Agency and U.S. Army TACOM each appear in recent awards, but at small dollar values ($11,270 and $47,030 respectively) for specialized equipment maintenance.

Recent activity is declining. The vendor received 8 awards in 2024, 3 in 2025, and 2 in 2026 year-to-date as of late May, down from a baseline of 6 to 9 awards per year in 2022 and 2023. Recompete exposure in the next twenty-four months is minimal: only 3 awards totaling $90 thousand face ultimate completion dates within that window. The vendor operates exclusively as a prime contractor — no subcontract footprint appears in the source data — and holds no position on government-wide vehicles, BPAs, or indefinite-delivery IDIQs. All work flows through competitive purchase orders or SNAP reverse auction buys placed directly by customer agencies. PSC concentration reflects the product mix: Laboratory Equipment and Supplies (55 awards), Chemical Analysis Instruments (42 awards), and Maintenance and Repair of Equipment—Instruments and Laboratory Equipment (32 awards) account for the bulk of historical work. Total combined potential value across the 162-award footprint is $4.4 million, with $4.2 million obligated as of the snapshot date.
