UNSPSC 41115600: Electrochemical measuring instruments and accessories

UNSPSC 41115600 Electrochemical measuring instruments and accessories is a Class code that encompasses specialized analytical and laboratory measurement devices state and local governments procure for environmental monitoring, forensic analysis, materials testing, and research applications. Recent solicitations show actual purchasing focused on water quality testing reagents, specialized laboratory analyzers (chromatography systems, surface energy analyzers, cyanide analyzers, ion chromatography equipment), field instrumentation (sound level meters, noise dosimeters, pump calibrators), and electrochemical sensors for drinking-water compliance and forensic toxicology—substantially narrower than the abstract code title and reflecting mission-critical equipment for public health labs, environmental agencies, sheriff crime labs, and research universities. Mississippi State University, the University of Southern Mississippi, the State of Oregon Occupational Safety and Health Division, Texas HHSC, Brazoria County Sheriff's Office, Broward County, and county health departments dominate recent activity, indicating a buyer base split between state environmental and occupational safety agencies, higher-education research institutions, and county forensic and public-health operations. The geographic spread concentrates in Mississippi, Oregon, Texas, and Florida, with secondary activity in Michigan, Illinois, Georgia, and Wisconsin.

Recent representative opportunities include the Texas Health and Human Services Commission (HHSC) procuring IDEXX Colilert reagents and water bottles for bacteriological testing with a historical annual spend of $70,050 to $90,000 and a standing-order delivery cycle (RFQ due July 8, 2026); Brazoria County, Texas requesting sealed bids for a complete Liquid Chromatograph-Triple Quadrupole Mass Spectrometer (LC-QQQ) system for the Sheriff's Office Crime Lab with a $300,000 estimated budget and May 12, 2026 deadline; the State of Oregon OSHA Division issuing RFQs for sound level meters, indoor air quality monitors, respirator fit testing devices, and pump calibrators across multiple notices in June 2026; and Mississippi State University posting multiple sole-source notices for specialized research instrumentation including a WRK String Spectrometer ($25,695), an Anton Paar DMA module ($64,800), and a QIAGEN Tissuelyser III. Sole-source procurement is dominant across the dataset, reflecting equipment proprietary control by manufacturers and integration constraints with existing research infrastructure. The code shows steady quarterly activity with short response windows (typically 7–14 days) and responses directed to university procurement offices, state agency purchasing divisions, and county e-procurement systems via Bonfire, PHLContracts, or OregonBuys platforms.
