UNSPSC 41115837: Particle counter and sizer

Automated analyzer for fluid pariticle enumeration and size distribution analysis

UNSPSC 41115837 Particle counter and sizer is a Commodity code, but the recent state and local opportunities posted under it bear little substantive relation to particle counting or sizing equipment. The recent solicitations tagged to this code instead span emergency medical services equipment (intraosseous infusion needles and drills, automated external defibrillators and batteries, transport ventilators), laboratory and clinical measurement systems (metabolic analyzers, computerized dynamic posturography systems, clinical laboratory autoanalyzers), blood pressure monitoring accessories, and tangential procurements such as litigation support services and pharmacy benefit management administration. State and local buyers posting under this code include county governments (Williamson County, Marion County, Cobb County School District, Clay County), university entities (Lamar University, Georgia State University via GSW State University), city procurement offices (City of Orlando), transit authorities (Trinity Metro / Fort Worth Transportation Authority), and a statewide cooperative purchasing vehicle (Sourcewell on behalf of multiple Washington and other jurisdictions). The code shows activity across Texas, Florida, Georgia, Minnesota / Washington, and scattered post dates from late March through late June 2026, but no geographic concentration emerges from the limited sample.

Representative recent opportunities include Williamson County's sole-source procurement (26SS60) for EZ-IO intraosseous infusion equipment—needles, stabilizers, and drills for Emergency Medical Services, due July 7, 2026; Cobb County School District's quote request (Q27009) for AED equipment, batteries, and accessories with approximately $50,000 in estimated expenditures, due July 6, 2026; GSW State University's eRFQ (54200ERFQ0000017492026) for a metabolic measurement system–compact analyzer module, due May 4, 2026; and Marion County, Florida's re-solicitation (21SS-044) for blood pressure cuffs, hoses, and LIFEPAK 15S accessories for Marion County Fire Rescue, due May 6, 2026. The code exhibits minimal alignment between its nominal scope and actual buying activity, suggesting either mislabeling in the state and local tagging system or that the category has become a catch-all for clinical and emergency medical equipment procurements that do not fit elsewhere in the taxonomy.
