UNSPSC 41181609: Rocket immunoelectrophoresis equipment

In this classification, Rocket immunoelectrophoresis equipment connotes a device used to perform a specific test on proteins by using a procedure called rocket immunoelectrophoresis. In this procedure, an electric current causes the protein in solution to migrate through agar gel containing specific antisera. The protein precipitates with the antisera in a rocket-shaped pattern, giving the name to the device. The height of the peak (or the area under the peak) is proportional to the concentration of the protein.

US FDA regulates Rocket immunoelectrophoresis equipment under 21 CFR 866.4830 and under FDA product code JZX.

UNSPSC 41181609 Rocket immunoelectrophoresis equipment is a Commodity code that shows no relevant recent state and local procurement activity. The code's abstract designation—immunoelectrophoresis apparatus—does not align with the state and local opportunities posted under this number since July 2026. Instead, the opportunities tagged to this code span unrelated categories: timeclock equipment (Mississippi State University), hydrogen generator supplies (City of Philadelphia), fire alarm components (Mississippi State University), spectrometer instruments and sample collectors (Mississippi State University), water quality testing reagents (Texas Health and Human Services Commission), X-ray diffractometer components (State of Oregon), and early childhood learning materials (Mississippi State University). None of these solicitations involve rocket immunoelectrophoresis equipment or any immunoelectrophoresis apparatus.

The issuing bodies are predominantly higher-education institutions—Mississippi State University alone appears multiple times—joined by state health and safety agencies, county procurement offices, and municipal departments. The geographic footprint spans Texas, Mississippi, Oregon, Pennsylvania, Wisconsin, and Florida, with no concentration in any single jurisdiction. The mismatch between the UNSPSC code's nominal scope and the actual procurement activity suggests either a cataloging error across multiple state and local procurement systems or that the code is rarely used for its stated purpose. For business development professionals, this code warrants a skip: the recent activity provides no actionable signal about demand for rocket immunoelectrophoresis equipment, and the solicitations posted under it do not represent a market opportunity in that equipment category.
