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, a Commodity code, covers laboratory chromatography consumables and related analytical instrumentation supplies that state and local governments procure for forensic, toxicology, and clinical laboratory operations. Recent solicitations show state and local buyers acquiring not only thin-layer chromatography supplies but also complementary laboratory equipment, reagents, and consumables used in DNA analysis, drug screening, and mass spectrometry applications. The Texas Comptroller of Public Accounts and Brazoria County Sheriff's Office represent the issuing-body mix, spanning a state procurement office and county law enforcement, both buying specialized laboratory supplies and instruments for crime lab operations.

The code shows recent activity concentrated in Texas. The Texas Comptroller's IFB 304T-27-175A1.1, posted September 23, 2026, with responses due October 20, 2026, solicits proprietary chemical laboratory equipment and supplies including genetic analyzer components, DNA sequencing kits, quantification standards, RapidHIT cartridges, and Direct ELISA kits for controlled-substance screening—serving the Texas Department of Public Safety and Parks and Wildlife statewide. Brazoria County's RFP #26-48, posted May 12, 2026, with bids due the same day, seeks a Liquid Chromatograph-Triple Quadrupole Mass Spectrometer system for the Sheriff's Office Crime Lab. Both opportunities specify brand or SKU constraints, require cold-chain logistics compliance, and demand manufacturer warranties and replacement guarantees. The Texas Comptroller procurement involves multiple vendor lines (Life Technologies, Promega, Qiagen, Immunalysis, ANDE) with quantities ranging from 8 to 5,000 units per line item and a firm fixed price structure with 1.5% Texas SmartBuy administrative fee applied to purchases.
