UNSPSC 41116018: Particle sizer and counter analyzer reagent

All reagents utilized for automated fluid particle enumeration and size distribution analysis

UNSPSC 41116018 Particle sizer and counter analyzer reagent is a Commodity code tracking laboratory reagents, media, standards, and consumable supplies for microbial identification, sequencing, and analytical testing used by state and local public health agencies, environmental laboratories, and academic medical centers. Recent state and local solicitations under this code show procurement of next-generation sequencing consumables (respiratory pathogen detection kits, whole genome sequencing reagent bundles for foodborne illness and SARS-CoV-2 analysis), culture media for pathogen identification (Escherichia coli, Listeria, Enterobacter detection), solid phase extraction disks for drinking water compliance testing, chromatography columns and chemical standards for gas chromatography analysis, spiking solutions for forensic and analytical applications, and comprehensive biotech research catalogs spanning antibodies, genomics reagents, immunoassay kits, and molecular biology consumables. Issuing bodies include state departments of health (Texas HHSC/DSHS, Mississippi State Department of Health), state government agencies (California), academic medical centers (University of Texas Health Science Center at San Antonio), and municipal procurement offices (City of Philadelphia). Texas agencies dominate recent activity, posting six of twelve visible opportunities between February and June 2026, reflecting sustained procurement of laboratory supplies tied to wastewater surveillance and foodborne illness detection programs.

Representative recent solicitations span Texas Health and Human Services Commission IFB HHS0017272 (Consumables Respiratory Panel Kits for MiSeq Instrumentation, response due May 19, 2026, historical value $35,050–$90,000), Texas HHSC IFB HHS0017132 (Culture Media Test for foodborne and waterborne pathogen detection, response due June 2, 2026, historical value $187,340 for FY2026), Mississippi State Department of Health sole-source procurement for Illumina whole genome sequencing kits and reagents (estimated total cost $393,667.98, objection deadline May 14, 2026), University of Texas Health Science Center at San Antonio RFP 745-26-P19 (Biotech Research, Clinical Diagnostics, and Equipment Catalog with approximately 8,768 line items ordered in prior contract year, proposals due June 4, 2026), and State of California RFB IS-26200845 (MyCodeDR Reagents, bids due April 29, 2026). Geographic concentration centers on Texas and Mississippi, with secondary activity in California and Pennsylvania. Procurement mix splits between competitive sealed bids (Texas IFBs, California RFBs) and sole-source awards (Mississippi Illumina and Clear Labs reagents justified by equipment compatibility), with contract terms typically six months to one year initial periods and optional renewals. No HUB set-asides are mandated across the visible opportunities; California solicitations include CBE preference but do not restrict competition.
