UNSPSC 47101613: Buffer solutions

UNSPSC 47101613 Buffer solutions is a Commodity code covering calibration and maintenance chemicals for water quality monitoring equipment, specifically buffer solutions and related chemical standards used to maintain and calibrate instruments like Hydrolab and In-Situ Sondes. State and local governments procure these products through water quality departments and environmental monitoring programs to ensure accurate measurement of pH, conductivity, temperature, turbidity, and dissolved oxygen in municipal water systems and monitoring networks. The work involves supplying specified chemical formulations—pH buffers at standardized levels (7.00, 10.00, 4.01), conductivity standards, deionized water, redox buffers, and sensor storage solutions—typically under as-needed ordering arrangements rather than fixed-quantity commitments. Water utilities and environmental agencies issue these solicitations; the mix of issuing bodies spans municipal water departments and, likely, regional environmental or natural-resource agencies, though recent activity in the dataset is limited to municipal buyers.

The City of Austin, Texas posted an IFB for chemicals to maintain Hydrolab and In-Situ Sondes on July 13, 2026, with bids due August 13, 2026 (IFB 6300BYS1059). The solicitation applied both a Small Business Preference program and a Local Business Preference (for entities headquartered in the Austin-Round Rock-San Marcos Metropolitan Statistical Area), with participation optional and not affecting bidding eligibility. The scope comprised eight specified chemical items in the buffer-solutions category, with pricing all-inclusive of shipping to the Austin area, administrative fees, and overhead. The City encouraged use of certified Small Business subcontractors where feasible but determined that MBE/WBE subcontracting goals did not apply due to insufficient subcontracting opportunities. Recent activity under this code is limited to the Austin solicitation; broader geographic or issuing-body patterns are not supported by the available data.
