UNSPSC 41142107: Collapse oxidation-reduction titrants

In this classification, this entry connotes a titrant of Collapse oxidation-reduction used as a reagent in clinical chemistry testing.

UNSPSC 41142107 Collapse oxidation-reduction titrants, a Commodity code, encompasses certified reference materials and reagent kits used in forensic and toxicological analysis by state and local crime labs, health departments, and law enforcement agencies. State and local governments procure these under the code as standardized drug standards, immunalysis reagent kits for substance screening, and DNA screening kits for method validation and evidentiary sample analysis. The issuing bodies are primarily state health and criminal justice agencies—the Texas Department of Public Safety, Florida Department of Law Enforcement (pass-through), Texas Health and Human Services Commission on behalf of the Department of State Health Services, and Texas Department of Criminal Justice—alongside county forensic laboratories such as Pinellas County, Florida. Work under the code includes procurement of Direct ELISA testing kits for cannabinoids, opiates, PCP, amphetamines, barbiturates, and other controlled substances; certified reference drug standards with ISO/IEC 17025 and ISO 17034 accreditation; and DNA screening and alignment marker kits for laboratory instrumentation validation.

Recent activity concentrates in Texas and Florida. The Texas Department of Public Safety issued IFB 405-26R0008445A on July 9, 2026, for immunalysis reagent kits with bids due July 23, 2026, covering 12 line items of Direct ELISA testing kits and phosphate-buffered saline solution. The Texas Health and Human Services Commission conducted competitive IFB HHS0016902v2 for QIAxcel and QIAamp DNA screening kits, with a January 29, 2026 response deadline and historical annual spend between $25,050 and $30,000. Pinellas County, Florida, issued Invitation to Quote 26-0305-ITQ on April 23, 2026, for certified reference drug standards under the Paul Coverdell Forensic Sciences Improvement Act Program, with approximately $49,034 of a $72,126.85 federal award designated for drug standards and laboratory equipment; the county offers preference to certified Small Business Enterprises. These solicitations use IFB, IFQ, and ITQ notice types with firm pricing requirements and extended qualification standards including vendor performance ratings, financial documentation, and compliance with federal forensic accreditation standards.
