UNSPSC 41142040: Potassium test system

In this classification, Potassium test system connotes a device used to measure Potassium levels. US FDA regulates Potassium test system under 21 CFR 862.1600 and under FDA product code MZV.

UNSPSC 41142040 Potassium test system (Commodity) covers diagnostic and forensic testing reagents and kits that state and local governments procure for laboratory analysis of controlled substances, toxicology screening, and environmental pathogens. The recent opportunities under this code show procurement of Direct ELISA immunalysis reagent kits for drug screening, certified reference material drug standards for forensic validation, DNA screening kits for laboratory analysis, and specialized testing equipment with associated reagent systems for mosquito-borne virus detection. State agencies dominate the issuing bodies—the Texas Department of Public Safety, Texas Health and Human Services Commission, Texas Department of Criminal Justice, Florida Department of Law Enforcement (as pass-through), and Illinois Department of Financial and Professional Regulation—alongside county-level forensic laboratories and public health units. These buyers seek reagents and standards meeting strict accreditation requirements such as ISO/IEC 17025:2017 and ISO 17034:2016, with emphasis on purity specifications and certificates of analysis for evidentiary or quality-assurance purposes.

The code sees concentrated recent activity in Texas and Florida, with secondary activity in Illinois. Representative recent opportunities include the Texas Department of Public Safety's IFB 405-26R0008445A (posted July 9, 2026, due July 23, 2026) for 12 line items of Direct ELISA cannabinoid and opioid testing kits; Pinellas County, Florida's Invitation to Quote 26-0305-ITQ (posted April 23, 2026) for 131 line items of certified drug reference standards funded under the Paul Coverdell Forensic Sciences Improvement Act with $72,126.85 in federal funds; and the Texas Health and Human Services Commission's IFB HHS0016902v2 (due January 29, 2026) for QIAxcel and QIAamp DNA screening kits with historical spending of $25,050.00 to $30,000.00 in Fiscal Year 2025. Forensic laboratories and state crime labs are the primary end users. Set-aside preferences vary by jurisdiction—Pinellas County offers SBE preference with five-percent price advantage, while Texas solicitations incorporate HUB subcontracting plan requirements for WBE, MBE, and SDVOSB participation. Response dates cluster in spring and mid-summer months.
