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 that shows minimal recent activity aligned with its nominal scope. State and local governments rarely procure nephelometers—laboratory instruments for measuring turbidity in clinical samples—as reflected in the recent opportunities block, which contains no active solicitations for nephelometers or related clinical laboratory equipment under this code. The three most recent postings tagged to this code (Mississippi State University timeclock equipment, City of Philadelphia hydrogen generator supplies, and Mississippi State University fire alarm components) are plainly unrelated to nephelometer acquisition or clinical diagnostics. The source does not support recent solicitation activity, issuing-body mix, geographic spread, or representative opportunities for nephelometer procurement at the state and local level.

State and local procurement offices appear not to be sourcing nephelometers through this code tier at present. If your firm pursues clinical laboratory equipment contracts with educational institutions, health departments, or county public health labs, monitor higher-tier codes within diagnostic and laboratory instrument families (Class codes in the 41151000 range) for broader instrument solicitations that may bundle or include turbidity measurement capability. The mismatch between code nomenclature and recent state-local activity suggests either that nephelometer demand is episodic and not currently active, or that issuing bodies are tagging these procurements elsewhere in the taxonomy.
