UNSPSC 41151507: Matching fluid a colorimetric preparation

In this classification, this entry connotes a standardized preparation made of Matching fluid a, used in a colorimetric Clinical laboratory test.

UNSPSC 41151507 Matching fluid a colorimetric preparation, Commodity tier, covers laboratory reagents and testing fluids that state and local governments procure for analytical and diagnostic work. Recent solicitations under this code show little direct purchasing of matching fluids or colorimetric preparations; instead, the tagged opportunities span laboratory services (specimen collection, testing execution, and result reporting), laboratory equipment repair and maintenance, spectrophotometer procurement, transformer oil testing, and various specialized testing and inspection services. The issuing bodies include county health departments (Marion County, Oregon), state health agencies (Texas Department of State Health Services), city utilities (City of Tampa, Lubbock Power & Light), transit authorities (Broward County Transportation Department), and municipal departments (Waterford, Connecticut fire station construction inspection). None of the recent opportunities directly solicit matching fluids or colorimetric standards as line-item purchases or standalone products.

The geographic spread of posted opportunities spans Oregon, Texas, Florida, and Connecticut, with no concentration indicating where this specific commodity code drives meaningful procurement volume. The most recent opportunity explicitly tagged under this code — Marion County's ITB SO1814-26 for laboratory testing services and phlebotomy (due July 24, 2026) — encompasses specimen collection, courier services, and phlebotomist labor rather than chemical reagents or reference fluids. The Texas Department of State Health Services' repair and maintenance contract for laboratory equipment (IFB HHS0017421, due July 6, 2026) addresses equipment servicing but not consumables. The City of Tampa's RFQ 26-P-00372 for a Heck DR4900 Spectrophotometer (due June 12, 2026) procures the instrument itself, not the matching fluids required to operate it. The code shows minimal relevant recent activity and does not align clearly with the actual scope of the opportunities it tags in state and local systems.
