UNSPSC 12141747: Tungsten W

UNSPSC 12141747 Tungsten W is a Commodity code covering specialized laboratory and forensic reagents, consumables, and reference materials procured by state and local agencies for DNA analysis, drug screening, pathogen detection, and quality control testing. State and local governments buy under this code primarily through forensic science departments, public health laboratories, water utilities, and law enforcement agencies seeking branded or proprietary laboratory supplies where equivalent substitutes do not exist or are contractually restricted. The work spans next-generation sequencing (NGS) consumables and reagents, genetic analyzer components, DNA quantification standards, rapid diagnostic testing kits (including Shiga Toxin detection and cannabinoid/opioid screening), precipitant solutions, and forensic reference materials from manufacturers including Life Technologies/Thermo Fisher Scientific, Promega, Qiagen, Immunalysis/Abbott, ANDE Corporation, Sigma-Aldrich, and Cerilliant. Issuing bodies include state comptroller and forensic science departments, city water utilities and laboratory services divisions, county sheriffs' offices, public health laboratories, and university research procurement offices. Recent solicitations reflect a mix of single-source proprietary procurements and brand-only restrictions justified by equipment compatibility, regulatory compliance, and established laboratory protocols.
