UNSPSC 41142122: Sodium thiosulfate titrants

In this classification, this entry connotes a titrant of Sodium thiosulfate used as a reagent in clinical chemistry testing.

UNSPSC 41142122 Sodium thiosulfate titrants is a Commodity code that captures state and local procurement of laboratory reagents, testing kits, and certified reference materials used in forensic drug analysis, toxicology screening, and analytical method validation. State and local issuing bodies soliciting under this code include state law enforcement and health agencies, county forensic laboratories, and health and human services departments. The scope of work centers on Direct ELISA testing kits for multi-substance screening (cannabinoids, opiates, PCP, amphetamines, cocaine, benzodiazepines, and other controlled substances), phosphate-buffered saline solutions, certified drug reference standards with ISO/IEC 17025 accreditation, and supporting laboratory consumables required to maintain forensic laboratory compliance with national accreditation standards. Vendors responding to these solicitations must meet rigorous quality and documentation requirements, including certificates of analysis, purity certifications exceeding 97% for solid materials, and compliance with federal drug scheduling and DEA licensing rules where controlled substances are involved. Financial documentation, vendor performance ratings, and state-specific certifications (Texas identification numbers, franchise tax compliance, debarment affirmations) are standard requirements across recent opportunities.

Activity under this code concentrates in Texas and Florida, with representative recent opportunities spanning multiple issuing bodies. The Texas Department of Public Safety Crime Lab Division posted IFB 405-26R0008445A on July 9, 2026, due July 23, 2026, for Direct ELISA testing kits across 12 substance categories with estimated quantities of 3 to 30 units per line item. Pinellas County, Florida, in partnership with the Florida Department of Law Enforcement, issued Invitation to Quote 26-0305-ITQ on April 23, 2026, for 131 line items of certified drug reference standards, with SBE preference for responding vendors and federal funding of $72,126.85 through the Paul Coverdell Forensic Sciences Improvement Act Program. The Texas Health and Human Services Commission, on behalf of the Department of State Health Services, conducted competitive IFB HHS0016902v2 due January 29, 2026, for QIAxcel and QIAamp DNA screening kits with a historical fiscal year 2025 value of $25,050.00 to $30,000.00. Contract terms typically run one year with extension options, and issuing bodies commonly reserve the right to terminate for convenience with 30 days' notice.
