UNSPSC 41151625: Refractometer for clinical use

In this classification a refractometer for clinical use is a device intended to determine the amount of solute in a solution by measuring the index of refraction (the ratio of the velocity of light in a vacuum to the velocity of light in the solution). The index of refraction is used to measure the concentration of certain analytes (solutes), such a plasma total proteins and urinary total solids. US FDA regulates Refractometer for clinical use under 21 CFR 862.2800 and under FDA product code JRE.

UNSPSC 41151625 Refractometer for clinical use (Commodity) does not align with recent state and local procurement activity in the provided source material. The 24 most recent opportunities posted under or near this code span July through October 2026 and cover specialized laboratory and research equipment including UAVs, microscopes, mass spectrometry systems, induction furnaces, 3D printers, cold spray systems, acoustic receivers, and various analytical instruments—none of which are refractometers or clinical-use optical measurement devices. The misalignment suggests either a data-tagging error in the source or a commodity classification that does not reflect current market demand.

The issuing bodies in this dataset are primarily research universities (Mississippi State University, University of Mississippi, University of Wisconsin-Madison, Texas State University, Texas A&M University System, Midwestern State University) and one state environmental agency (Illinois EPA), alongside county water-quality laboratories and state wildlife agencies. Mississippi State University alone accounts for more than half the solicitations, issuing sole-source notices for specialized research equipment including cold spray systems ($951,755.46), 3D printing platforms ($1.253 million), custom robotic sprayers, and precision instrumentation across materials science, agricultural, and engineering programs. Geographic concentration is heavy in Mississippi and Wisconsin, with secondary activity in Texas, Illinois, and Oregon. The procurement mechanisms are dominated by sole-source notices (approximately two-thirds of the visible activity), with the remainder split between ITBs, RFPs, and RFBs. No refractometer solicitations appear in the record; the code warrants investigation for accuracy.
