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, a Commodity code, spans laboratory reagents and consumables used in diagnostic and environmental testing workflows by state and local health departments, universities, and county agencies. State and local governments procure under this code clinical diagnostic reagents for pathogen detection and antimicrobial resistance screening; environmental testing reagents for drinking water, dairy, and shellfish safety; whole genome sequencing kits and reagent bundles for foodborne illness surveillance and variant monitoring; culture media and quality control materials; and specialized solid-phase extraction disks and chromatography consumables for compliance testing under EPA and FDA protocols. Recent opportunities reflect procurement of reagents compatible with existing lab instrumentation—Biomerieux systems, Illumina sequencers, Clear Dx systems, MiSeq platforms, and gas chromatography equipment—indicating that vendors compete on product compatibility, pricing, and ability to meet EPA or FDA specifications rather than on open-category reagent supply. Issuing bodies include state health departments (Texas DSHS, Mississippi State Department of Health), county health agencies (Gwinnett County, Georgia), and academic research centers (University of Texas Health Science Center at San Antonio).

Recent activity concentrates in Texas and Mississippi. Texas Health and Human Services Commission has issued multiple IFBs for lab consumables and reagents—including culture media for food, water, dairy, and shellfish testing (HHS0017881, due August 26, 2026), respiratory pathogen detection kits for wastewater surveillance (HHS0017272), standards and instrument parts for drinking water analysis (HHS0017271), and solid-phase extraction disks for EPA compliance testing (HHS0017287)—with historical fiscal year values ranging from $25,000 to $90,000 per procurement. Mississippi State Department of Health conducted sole-source procurements for Illumina sequencing reagents and Clear Labs WGS kits, each totaling several hundred thousand dollars annually. The University of Texas Health Science Center at San Antonio issued an RFP for a comprehensive biotech research and diagnostics catalog with pricing discounts off MSRP (RFP 745-26-P19, due June 4, 2026), and Gwinnett County requested drug testing supplies compatible with a specific analyzer platform (IFB PE77023NONST2027000000764, due October 14, 2026). The City of Philadelphia issued a micro purchase for extraction columns (May 30, 2026), representing the only non-health-agency activity in the recent sample.
