UNSPSC 41151621: Nephelometer for clinical use

In this classification a nephelometer for clinical use is a device intended to estimate the concentration of particles in a suspension by measuring their light scattering properties (the deflection of light rays by opaque particles in their path). The device is used in conjunction with certain materials to measure the concentration of a variety of analytes US FDA regulates Nephelometer for clinical use under 21 CFR 862.270 and under FDA product code JQX.

UNSPSC 41151621 Nephelometer for clinical use is a Commodity code. The recent state and local opportunities tagged under this code show no purchasing activity aligned with nephelometers or clinical laboratory instruments; instead, the tagged records document acquisitions of research equipment, specialized analytical systems, and scientific instruments across diverse application areas—from cold spray additive manufacturing systems and X-ray diffractometers to microfluidic processors and acoustic telemetry receivers. The mismatch between the code's nominal scope and the actual procurements indexed to it suggests either a data-classification error in the opportunities block or dormant procurement volume under this specific code.

The opportunities that carry this UNSPSC designation originate almost exclusively from Mississippi State University and the University of Mississippi, with secondary activity from Midwestern State University, the University of Wisconsin–Madison, and other academic institutions, along with isolated state-agency acquisitions from Oregon and Illinois. Mississippi State University dominates the recent record, filing over thirty sole-source notices and sealed-bid requests between June and October 2026, predominantly for research-grade equipment purchases ranging from $6,000 to $1.253 million. No state health department, clinical laboratory, hospital system, or public health agency appears in the recent-opportunities block, and no procurement explicitly names nephelometry, nephel­ometric measurement, turbidity analysis, or clinical laboratory diagnostics. Given this pattern, the code appears inactive or misclassified in current state and local procurement indexing, making it unsuitable for active pursuit absent clarification of its actual use or reallocation to the correct commodity category.
