UNSPSC 41142104: Calcium titrants

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

UNSPSC 41142104 Calcium titrants (Commodity) encompasses laboratory reagents and reference standards used in forensic drug analysis, toxicology screening, and chemical identification — though recent state and local activity shows the code capturing a broader set of analytical laboratory consumables including immunoassay kits, DNA screening kits, and certified drug reference materials rather than calcium titrants specifically. State and local buyers under this code include state crime laboratories, state health and human services agencies, county forensic laboratories, and state departments of public safety, with Texas and Florida showing the most recent procurement volume. The work involves establishing supply contracts for direct ELISA testing kits (cannabinoids, opiates, amphetamines, benzodiazepines, and other controlled substances), certified reference materials meeting ISO/IEC 17025 accreditation standards with purity thresholds and expanded uncertainty specifications, and DNA screening kits for laboratory method validation and evidentiary analysis.

Recent opportunities span the Texas Department of Public Safety's IFB 405-26R0008445A (due July 23, 2026) for immunalysis reagent kits comprising 12 line items of direct ELISA testing kits for substance analysis; Pinellas County, Florida's Invitation to Quote #26-0305-ITQ (due April 23, 2026) for 131 line items of certified drug reference standards funded through the Paul Coverdell Forensic Sciences Improvement Act Program with approximately $49,034 allocated for drug standards and laboratory equipment; and the Texas Health and Human Services Commission's IFB HHS0016902v2 (due January 29, 2026) for QIAxcel and QIAamp DNA screening kits with a historical spending baseline of $25,050 to $30,000 annually. Pinellas County applies a five percent price preference to Certified Small Business Enterprises submitting within the first five business days. The Texas Department of Criminal Justice also posted solicitation IW248126 in April 2026 requiring HUB Subcontracting Plan compliance, though specific goods and services are not disclosed in available documentation. Delivery requirements typically specify state laboratory loading docks; contracts run 12 months with extension options; and vendors must hold current DEA licensing for controlled substance reference materials and comply with federal accreditation standards.
