UNSPSC 41113051: Oxidation reduction tester

A tester that measures the ratio of oxidation-reduction of soluble substances within the solution.

UNSPSC 41113051 Oxidation reduction tester, a Commodity code, encompasses laboratory and testing equipment used by state and local governments to measure oxidation-reduction potential in fluids and materials—primarily spectrophotometers, analyzers, and related hardware for water quality, environmental, and utility testing applications. State and local issuers posting under this code span county health departments, municipal water and waste-to-energy utilities, electric cooperatives, university research facilities, and transportation authorities. Recent opportunities show activity across laboratory service procurement (specimen testing and phlebotomy), equipment repair and maintenance contracts (sterilizers and steam generators), direct equipment purchases (spectrophotometers), and utility-specific diagnostic services (insulating oil analysis for electrical equipment). Marion County, Oregon issued an ITB for laboratory testing services and phlebotomy for Adults in Custody with responses due July 24, 2026; the Texas Department of State Health Services (DSHS) posted an IFB for preventive maintenance and 24-hour technical support on laboratory washers and sterilization equipment at the South Texas Laboratory in Harlingen, with bids due July 6, 2026 and historical annual service value ranging from $25,050 to $40,000; the City of Tampa solicited quotes via RFQ for a Heck DR4900 spectrophotometer replacement at the McKay Bay Waste to Energy facility; and Lubbock Power & Light released an RFP for annual insulating oil testing and laboratory services across approximately 20 substations, with proposals due July 22, 2026, requiring ISO/IEC 17025 accreditation and utility experience.

Geographic activity concentrates in Texas (DSHS South Texas Laboratory, Lubbock Power & Light), Florida (Tampa, Orlando), and Oregon (Marion County), with secondary presence in Arizona (ChargePoint maintenance) and Connecticut (materials testing). Testing and laboratory support services dominate the recent posting mix, particularly diagnostics tied to utility operations and environmental compliance. Opportunities favor vendors with OEM certifications, relevant accreditations (ACI, AWS, ICC, ASNT, ISO/IEC 17025), and demonstrated experience serving similar public agencies. Equipment sales appear episodic and tied to facility replacements rather than routine procurement cycles, while service contracts (maintenance, repair, diagnostics) show steady demand and often include multi-year terms with renewal options. A sole-source notice from the City of Orlando for technical support on a FIAnalyzer-3000 system indicates incumbent relationships can anchor volume once established. The code shows meaningful activity through mid-2026 and merits active monitoring for service contract opportunities, particularly in utilities and public health contexts where testing frequency and compliance obligations drive ongoing demand.
