UNSPSC 41181600: Immunology laboratory equipment and reagents

In this classification, these entries include the equipment and reagents used in association with microbiological laboratory procedures.

UNSPSC 41181600 Immunology laboratory equipment and reagents is a Class code describing specialized analytical instruments, reagents, and consumables that state and local public health, environmental, and forensic laboratories procure for bacteriological and chemical analysis of environmental samples, forensic evidence, and clinical specimens. Recent solicitations show state and local buyers acquiring products ranging from COLILERT bacteriological reagents for drinking water testing through Liquid Chromatograph-Triple Quadrupole Mass Spectrometers (LC-QQQ) for forensic drug and toxicology analysis, Ion Chromatography Systems for contaminant detection, and Gas Chromatograph-Flame Ionization Detectors for air quality monitoring—a portfolio dominated by high-end analytical chemistry and microbiology equipment paired with consumable test kits and supporting reagents.

Issuing bodies span state environmental and health agencies, county sheriffs' offices and public health departments, university research facilities, and municipal testing laboratories. The Texas Health and Human Services Commission (DSHS) and State of Oregon Department of Consumer and Business Services (Oregon OSHA Lab) appear as repeat buyers of calibration equipment, analytical instruments, and quality-assurance consumables; Brazoria County, Texas and the City of Albuquerque stand out for forensic lab equipment and supplies procurement; and Mississippi State University and University of Southern Mississippi frequently post sole-source notices for research-grade analytical systems. Recent activity concentrates in Texas (HHSC COLILERT reagents for South Texas Laboratory, Brazoria County LC-QQQ for Sheriff's Office Crime Lab), Oregon (multiple OSHA Lab RFQs for noise dosimeters, pump calibrators, respirator fit testers), Mississippi (university procurements for microscopy systems, rheometers, aquaculture instrumentation), Florida (Broward County RFI for GC-FID maintenance), and Georgia (Gwinnett County jar testers for water reclamation). The Texas Health and Human Services Commission issued an RFQ for IDEXX COLILERT reagents and water bottles (July 8, 2026 close) supporting 1,000 monthly samples across eight counties, with historical annual spend $70,050–$90,000 and standing quarterly delivery requirements; Brazoria County issued an RFP for a complete LC-QQQ system with installation, training, and $300,000 federal DOJ Coverdell funding (May 12, 2026 close); and the State of Oregon posted multiple RFQs for SKC pump calibrators, TSI air quality monitors, and QuantiFit2 respirator fit testers (June 10 and June 23, 2026 closes) supporting occupational safety lab operations. The code shows steady baseline activity in state and local analytical testing with no apparent market disruption, though opportunity volume and dollar value remain modest relative to broader procurement segments.
