UNSPSC 41151623: Osmometer for clinical use

In this classification an osmometer for clinical use is a device intended to measure the osmotic pressure of body fluids. Osmotic pressure is the pressure required to prevent the passage of a solution with a lesser solute concentration into a solution with greater solute concentration when the two solutions are separated by a semipermeable membrane. The concentration of a solution affects its osmotic pressure, freezing point, and other physiochemical properties.

Osmometers determine osmotic pressure by methods such as the measurement of the freezing point US FDA regulates Osmometer for clinical use under 21 CFR 862.2730 and under FDA product code JJM.

UNSPSC 41151623 Osmometer for clinical use is a Commodity code that does not show recent state and local procurement activity aligned with its nominal scope. The code is indexed to equipment for measuring serum or plasma osmolarity in clinical laboratory settings, yet the recent opportunities posted under this code span specialized research instrumentation, equipment service contracts, and consumable supplies entirely unrelated to clinical osmometry — including unmanned aerial vehicles, precision metallurgical furnaces, microscopy systems, spectrometers, photon detectors, and reagent kits for water-quality and DNA analysis. The mismatch between the code name and the actual work being procured indicates either a cataloging error in the source data or a divergence between how the code is indexed and how issuing bodies are tagging their opportunities.

The issuing-body mix is dominated by Mississippi State University and the University of Mississippi, with secondary activity from other state universities (University of Wisconsin-Madison, Texas State University, Midwestern State University), state agencies (Mississippi Department of Wildlife, Fisheries, and Parks; Illinois State Police; Illinois Environmental Protection Agency; Oregon Department of Consumer and Business Services; Texas Health and Human Services Commission), and one county procurement office (Escambia County, Florida; Harris County, Texas). Geographic spread centers on Mississippi, with scattered activity in Wisconsin, Texas, Illinois, Oregon, and Florida. Because the recent opportunities are substantively unrelated to clinical osmometry, no representative examples of osmometer procurement can be drawn from this dataset. State and local procurement under UNSPSC 41151623 as applied to clinical osmometry should be evaluated using a separate, properly aligned source before committing resources to pursue this code.
