UNSPSC 41181606: Ouchterlony agar plate

In this classification, Ouchterlony agar plate connotes a device containing an agar gel used to examine antigen-antibody reactions. In immunodiffusion, antibodies and antigens migrate toward each other through gel which originally contained neither of these reagents. As the reagents come in contact with each other, they combine to form a precipitate that is trapped in the gel matrix and is immobilized. US FDA regulates Ouchterlony agar plate under 21 CFR 866.4600 and under FDA product code JZP.

UNSPSC 41181606 Ouchterlony agar plate is a Commodity code that classifies specialized microbiology laboratory media and culture supplies used in diagnostic and research settings. The recent state and local opportunities show virtually no procurement activity aligned with this code's scope. The source contains a single entry tagged with this UNSPSC number—a Mississippi State University sealed-bid solicitation (MSU2026111, "Recirculating Tailwater Reduces Nutrient Loss in Agriculture," due October 13, 2026)—but the available documentation provides no detail on quantities, specifications, or scope to confirm whether agar plates or any related culture media are actually being purchased. The remaining 39 opportunities in the dataset span research equipment (spectroscopy systems, microscopes, cold spray systems, induction furnaces), laboratory instruments (DMA units, high-speed cameras, acoustic receivers), facility equipment (fire alarm components, cooling tower media, livestock chutes), and specialized supplies (Rapid DNA cartridges, IDEXX water-quality reagents, hydrogen generator supplies), but none involve Ouchterlony agar plate procurement. This code shows minimal recent state and local procurement activity under the posted opportunities.

State and local buyers—including Mississippi State University, the University of Southern Mississippi, University of Wisconsin-Madison, Texas State University, Texas A&M University System, Midwestern State University, Harris County (Texas), Illinois State Police, Illinois EPA, Escambia County (Florida), the State of Oregon, the City of Philadelphia, the University of Mississippi, and the Texas Health and Human Services Commission—are actively issuing RFPs, RFQs, IFBs, and ITBs for laboratory and research equipment, but the agar-plate Commodity code does not surface in any representative procurement notice with sufficient scope detail to assess current demand or vendor opportunity.
