UNSPSC 41115612: Dissolved oxygen probes

UNSPSC 41115612 Dissolved oxygen probes is a Commodity code that state and local governments apply to medical-grade oxygen supply contracts, though the code name diverges significantly from the actual work being solicited. Recent activity shows procurement of medical-grade oxygen delivery services — including cylinder tank leasing, hydrostatic testing, periodic replenishment, and emergency-response logistics — rather than dissolved oxygen measurement instruments or probes. The issuing bodies under this code include municipal fire departments and emergency medical services divisions procuring oxygen supplies through their city contracting offices. The work encompasses full-service oxygen management including tank rotation, cap supply, pickup of empties, and compliance with OSHA and federal safety standards, with vendors expected to meet strict delivery schedules and maintain comprehensive insurance and certifications.

The City of Detroit Office of Contracting and Procurement issued an RFQ on April 9, 2026, on behalf of the Detroit Fire Department, requesting proposals for medical-grade oxygen in H-size tanks on a two-year contract, with a response deadline of April 24, 2026. The solicitation calls for approximately 1,400 tanks annually with weekly delivery or 24-hour emergency response to the Detroit Emergency Medical Services supply section at 1400 Erskine Street. Detroit's equalization-credit structure offers competitive advantages to certified Detroit-Based, Small Business, and Micro Business vendors ranging from 1% to 5% on bid evaluations, with the award methodology capped at 12 percent above the lowest responsible bid or $100,000, whichever is less. This appears to be the primary recent activity under the code; geographic concentration in Michigan and issuing-body activity is limited to the single Detroit municipal opportunity in the source.
