UNSPSC 41122502: Laboratory stoppers

UNSPSC 41122502 Laboratory stoppers (Commodity) encompasses rubber, silicone, and specialized sealing closures procured by state and local laboratories for sample collection, storage, and analysis workflows. Recent solicitations show state and local governments buying stoppers as part of broader laboratory consumables packages supporting analytical chemistry, water quality testing, wastewater surveillance, and environmental monitoring. The Texas Health and Human Services Commission and Department of State Health Services procured stoppers alongside columns, septa, liners, and detector components for Safe Drinking Water Act compliance analysis; the Colorado Department of Public Health and Environment acquired similar consumables as part of wastewater surveillance and genomic sequencing programs; and the City of Arlington, Texas solicited laboratory supplies and chemicals for its Laboratory Services and water treatment operations. Issuing bodies include state health departments, state environmental agencies, state transportation departments, municipalities, and specialized testing divisions within these jurisdictions. Most recent activity clusters in Texas and Colorado, with secondary activity in South Dakota and California, driven by federal water quality mandates, wastewater pathogen surveillance, and transportation infrastructure testing.

Representative recent opportunities include the Texas Health and Human Services Commission's September 2026 IFB for laboratory standards, consumables, and instrument parts (HHS0018026, due October 9, 2026) covering septa, liners, and related components with a fiscal year 2026 value of $50,000 to $75,000 and delivery to the DSHS laboratory in Austin; the City of Arlington's August 2026 annual requirements contract for laboratory supplies and chemicals (posted August 19, 2026, due September 17, 2026) serving the city's Laboratory Services and water treatment plants; and the Colorado Department of Public Health and Environment's May 2026 sole-source procurements for specialized reagents and consumables supporting wastewater surveillance and genomic sequencing platforms. Additional activity appears in South Dakota (September 2026 RFB for laboratory consumables, reagents, and chemicals) and California (April 2026 RFB for analytical laboratory equipment components). Most solicitations involve multi-year contracts or annual requirements agreements with optional renewals, firm fixed pricing, and delivery tied to state laboratory locations or municipal water facilities.
