UNSPSC 41115725: Thin layer chromatography plate

A sheet of metal, glass or plastic, that is coated with a thin layer of solid silica or alumina absorbent, and is utilized for thin layer chromatographic separation of a mixture's components through capillary action

UNSPSC 41115725 Thin layer chromatography plate is a Commodity code that captures laboratory analytical consumables and equipment used by state and local environmental and forensic agencies for chemical analysis. Recent state and local solicitations under this code center on specialized laboratory instrumentation and consumables—notably liquid chromatography-mass spectrometry systems for forensic toxicology, Waters Technologies brand supplies for PFAS and dioxane analysis in drinking water, and comprehensive laboratory testing services for municipal water and wastewater compliance. The issuing bodies are county sheriff's offices, city water and wastewater utilities, and municipal public health departments. Brazoria County, Texas's Sheriff's Office Crime Lab is soliciting a liquid chromatograph-triple quadrupole mass spectrometer (LC-QQQ) system with delivery, installation, training, and integration; the City of Tucson Water Department is procuring Waters Technologies consumables (polypropylene vials, screw caps, OASIS WAX cartridges, and SPE cartridges) for PFAS and dioxane analysis; and the City of Palm Bay, Florida is conducting a broader laboratory testing services ITB covering water, wastewater, groundwater, and industrial pretreatment analyses across multiple municipal facilities.

Recent activity concentrates in Texas, Florida, and Arizona. The Brazoria County RFP #26-48 for the LC-QQQ system shows a $300 million estimated budget with proposals due May 12, 2026, and award anticipated June 9, 2026, funding through the Paul Coverdell Forensic Sciences Improvement Grant Program with Davis-Bacon prevailing wage requirements. The City of Palm Bay ITB 19-ITB-26 for laboratory testing services closed March 17, 2026, with three bids received ranging from $80,872 to $107,946.10 annually; the incumbent was Advanced Environmental Laboratories, Inc. The City of Tucson IFB 240045 for Waters Technologies consumables closed October 20, 2023, with a mandatory pre-submittal conference held virtually and HUD Section 3 workforce requirements mandating 25 percent Section 3 worker labor hours. No recent opportunities in this sample carry exclusive set-asides, though the Tucson procurement imposes federal workforce compliance tied to HUD-assisted housing programs.
