About the company
Sotax Corp, doing business as Sotax A G, manufactures specialized pharmaceutical testing and laboratory equipment sold as prime contractor to federal agencies through firm-fixed-price purchase orders, with no participation in set-aside programs, IDIQs, or GWACs. Sotax is a for-profit corporation headquartered in Westborough, Massachusetts, and operates across NAICS 333314 (Analytical Laboratory Instrument Manufacturing) and related instrumentation categories, with a footprint of 37 prime federal awards totaling $3.6 million in combined potential value, of which $3.4 million (94%) has been obligated.
The vendor's customer concentration is highly concentrated on a single agency. The Department of Health and Human Services Food and Drug Administration accounts for 22 of 37 awards (81% by count) and $3 million of the combined potential value (83% of dollars), with the remaining volume split among Veterans Health Administration facilities and minor work at the National Institute of Standards and Technology and the Centers for Disease Control and Prevention. The FDA relationship is rooted in pharmaceutical equipment supply: Sotax sells dissolution testing systems, automated HPLC dissolution platforms, tablet analysis equipment (hardness, thickness, diameter testers), disintegration testers, and bench-top dissolution bath systems with media stations and UV-VIS spectrophotometers. Recent representative awards include two FDA purchase orders issued in August 2026—an automated solubility apparatus for $481 thousand and an automated HPLC dissolution platform for $350 thousand, both deliverable to Westborough by year-end 2026—a Total Small Business set-aside purchase order from FDA for two USP 1 & 2 dissolution apparatus systems with installation and qualification services for $236 thousand (May 2024), and a $393 thousand automated dissolution bath system order from FDA (August 2023). Veterans Affairs work centers on monitoring services; the firm received a $72 thousand purchase order modification from Veterans Integrated Service Network 22 in June 2025 to comply with Executive Order 14398, with a completion date of May 2030.
Activity has been modest and flat, with two or three awards per year over the past five years. Two awards carrying a combined potential value of $831 thousand face ultimate completion dates inside the next twenty-four months and represent near-term recompete exposure. Sotax operates exclusively as a prime contractor—no subcontract footprint appears in the source—and does not hold parent vehicle positions. The vendor's competitive posture centers on brand-name pharmaceutical instrumentation aligned to United States Pharmacopeia (USP) standards and methods, sold directly to federal buyers through competitive or brand-name-or-equal solicitations rather than through set-aside or centralized procurement vehicles.
