Buffalo Growth Partners today announced the acquisition of AGS Scientific, Inc., a Bryan, Texas-based provider of laboratory instruments, consumables, and technical services for the water, wastewater, and environmental testing industries. The transaction marks BGP's fourth acquisition and its first investment in the water and wastewater testing market—a compliance-driven, essential services vertical with significant consolidation opportunity.
Founded in 2003, AGS Scientific has served as a trusted partner for over two decades to laboratories, municipalities, industrial facilities, and environmental agencies that depend on accurate analytical testing to meet federal and state regulatory standards. The company specializes in mercury analysis instrumentation—distributing, installing, training, and servicing the precision equipment that labs and water systems rely on to protect public health and maintain EPA compliance. As the exclusive U.S. distributor for Nippon Instruments Corporation (NIC), the worldwide leader in mercury analyzers, AGS's Bryan facility has been designated as NIC's next Center of Excellence.
Water and wastewater testing is characterized by recurring, compliance-driven demand, high barriers to entry, and strong resilience through economic cycles. Increasing regulatory scrutiny at the federal and state level—including tightening EPA standards for PFAS, mercury, and other contaminants—continues to drive sustained investment in analytical testing infrastructure. BGP intends to build on AGS Scientific's market position and expand its presence across the broader water and wastewater testing ecosystem through organic growth and targeted add-on acquisitions.
"AGS Scientific has been a recognized leader in water testing for more than two decades. Their deep technical expertise, exclusive distribution relationships, and trusted reputation with laboratories and municipalities across the country make them the ideal foundation for our entry into this critical vertical. Water and wastewater testing sits at the intersection of public health and regulatory compliance—the demand is non-discretionary and growing. We see significant opportunity to invest in AGS's team and capabilities while expanding our footprint in this essential market."
— Robert Irving, Founder & CEO, Buffalo Growth Partners
"After more than 20 years building AGS Scientific into a leader in mercury analysis and laboratory services, we wanted a partner who understands what it takes to grow a technical services business without losing what makes it special. Buffalo Growth Partners brings hands-on operational experience and a proven track record of scaling service companies. We're excited about the growth opportunities ahead and confident that our customers and team are in the right hands."
— Jason Gray & Tracy Smith, Regional VPs, AGS Scientific
AGS Scientific will continue to operate from its Bryan, Texas headquarters and serve its national customer base without disruption. Customers can expect the same technical expertise, product quality, and responsive service they have relied on for over two decades—now supported by BGP's growth capital, operational resources, and acquisitive infrastructure. Near-term integration efforts will focus on strengthening service capabilities, investing in talent, and broadening geographic reach.
