UNSPSC 41181604: Immunofluorometer equipment

In this classification, Immunofluorometer equipment connotes a device to measure the fluorescence of fluorochrome-labeled antigen-antibody complexes. The concentration of these complexes may be measured by means of reflected light. A beam of light is passed through a solution in which a fluorochrome has been selectively attached to serum protein antibody molecules in suspension. The amount of light emitted by the fluorochrome label is detected by a photodetector, which converts light energy into electrical energy.

The amount of electrical energy registers on a readout system such as a digital voltmeter or a recording chart. This electrical readout is called the fluorescence value and is used to measure the concentration of antigen-antibody complexes. US FDA regulates Immunofluorometer equipment under 21 CFR 866.4520 and under FDA product code JZT.

UNSPSC 41181604 Immunofluorometer equipment, a Commodity code, shows no recent state and local procurement activity aligned with the code's nominal scope. The twenty-nine recent opportunities posted by state and local entities under or near this code span laboratory instruments, scientific equipment, and specialized research gear, but the majority involve analytical systems, surface characterization platforms, ion sources, microscopy equipment, drone platforms, and spectroscopy tools—none matching immunofluorometry work. The one tangentially related solicitation (Illinois State Police Department of Forensic Services IFB 26-493ISP-FOREN-B-51535, August 25, 2026) procures consumables and maintenance for a rapid DNA system, not immunofluorometer hardware. State and local issuers in the recent record are predominantly university purchasing offices (Mississippi State University, University of Mississippi, University of Wisconsin-Madison, Texas State University, Texas A&M University System, Midwestern State University) alongside a handful of state health or environmental departments and county water-quality labs. Mississippi State University alone appears in eighteen of the twenty-nine opportunities, typically posting sole-source notices for specialized research and instructional equipment.

Geographic activity clusters heavily in Mississippi (nineteen opportunities from state agencies and MSU), with secondary activity in Texas (three from university systems and health agencies), Wisconsin (five from UW-Madison), Illinois (two from state agencies), and scattered single postings in Oregon, Florida, and Pennsylvania. No recent opportunities identify immunofluorometer procurement specifically. If pursuing this code, target university research departments, state public-health laboratories, and water-quality or environmental monitoring agencies in Mississippi and Texas where recent activity shows sustained demand for analytical and scientific instrumentation—but verify the actual equipment need through pre-bid engagement, as the code's title and recent solicitations are misaligned.
