UNSPSC 41111502: Laboratory balances

UNSPSC 41111502 Laboratory balances, a Commodity code, covers the purchase and calibration of precision weighing equipment used in government and research laboratories, including analytical balances, reference weight sets, and associated maintenance and certification services. State and local governments procuring under this code seek both new equipment and ongoing calibration, maintenance, and metrological certification to meet accreditation standards such as ISO/IEC 17025 and NIST traceability. Issuing bodies include state environmental and natural-resources agencies (California Department of Fish and Wildlife), municipal water and laboratory services divisions (City of Arlington), and cooperative purchasing vehicles serving multiple member jurisdictions (Sourcewell, a Minnesota local government unit and service cooperative). The work typically involves equipment supply, on-site calibration with certified metrological laboratories, annual or multi-year maintenance contracts, and generation of calibration reports meeting regulatory accreditation requirements.

Recent activity spans California, Texas, and Minnesota. The California Department of Fish and Wildlife's IFB P2675012, posted September 10, 2026 with bids due October 5, 2026, sought three-year calibration and maintenance services for nine analytical balances, weights, thermometers, and pipettors at two Sacramento-area laboratories, with mandatory ISO/IEC 17025 accreditation and a $500 annual parts requirement plus hourly labor rates. The City of Arlington, Texas issued an annual requirements contract solicitation (RFQ 270018, due September 17, 2026) for laboratory supplies and chemicals supporting its Laboratory Services and water treatment operations. Sourcewell's RFP 26RFP111026, posted September 21, 2026 with proposals due November 10, 2026, sought laboratory and science equipment, supplies, and related technology and services as a contracting solution available to member public entities across the Sourcewell network. California's SBE and DVBE incentive programs appear in recent opportunities, and ISO/IEC 17025 or equivalent metrology accreditation is a recurring qualification requirement.
