UNSPSC 41151511: Matching fluid e colorimetric preparation

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

UNSPSC 41151511 Matching fluid and colorimetric preparation is a Commodity code. State and local governments buying under this code procure laboratory testing equipment, analytical instruments, and related services rather than matching fluids or colorimetric reagents themselves. Recent opportunities show demand concentrated in university research facilities, municipal utility laboratories, and specialized public health and environmental testing programs. Valencia College's sole-source purchase of a PGI Optics CORE Optical Surface Profilometer for precision lens measurement in its Advanced Science and Technology curriculum exemplifies the educational segment; Jackson State University's five-year license for the Schrodinger Small Molecule Drug Discovery Suite at $65,318.25 reflects research software licensing; and the City of Tampa's replacement of a Heck DR3900 Spectrophotometer with the newer DR4900 model at its McKay Bay Waste to Energy facility demonstrates municipal environmental testing infrastructure. The code also captures utility-scale photometric and analytical services — Lee County Port Authority issued two nearly identical e-quotes (postings 2026115BW and 2026061BW) for airfield photometric testing at Southwest Florida International Airport, and Lubbock Power & Light solicited oil testing and laboratory services for insulating fluid analysis across approximately 20 substations.

Recent activity clusters in Florida, Texas, Oregon, and Colorado. The majority of opportunities are sole-source or single-source procurements reflecting either exclusive vendor relationships (Teledyne Instruments for water quality analysis in Tampa; Gilson Engineering for Siemens process instrumentation in Collier County) or determinations that specific equipment models or integrated software suites have no equivalent alternatives. Competitive procurements remain limited; the City of Ocala's RFP for a Three-Phase Meter Test Board (RFPELE260570, due April 30, 2026) and the City of Phoenix's IFB for atmospheric monitoring instruments (IFB-27-0435, due September 4, 2026) are exceptions. Most recent posts carry response dates in 2026 with several showing past-due deadlines, indicating either stale postings or compressed procurement cycles typical of emergency or urgent utility purchases. Issuing bodies span municipal utilities, county environmental and water agencies, state health departments, and higher education institutions; no school districts or transit authorities appear in the recent record.
