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, yet the recent state and local opportunities tagged under it show no current procurement activity for osmometers or osmometry equipment. The source records fourteen recent solicitations spanning July 2026 back to March 2026, but none involve osmometric instruments or clinical osmometry services. The opportunities instead cover laboratory equipment (chromatography systems, spectrometers, mass spectrometers, analyzers), educational and research systems (microscopy, motion capture, wind tunnel testing, rheometry), municipal supplies (jar testers, pump calibrators, sound level meters), and miscellaneous goods (modular buildings, educational materials, early learning play sets). The code shows no decision-relevant activity at this time, and the mismatch between the code's nominal scope and actual postings suggests either a tagging error in the source data or a gap in current state and local osmometer procurement.

The issuing bodies in the sample span research universities (Mississippi State, University of Southern Mississippi, University of Wisconsin-Madison), city and county procurement offices (Philadelphia, Santa Clara, Brazoria County, Albuquerque, Broward County, Gwinnett County), state departments and agencies (Oregon DCBS, Texas HHSC, Michigan EGLE, Illinois EMA), and independent school districts (Klein ISD). Geographic spread includes Texas, Mississippi, Florida, Georgia, Oregon, Michigan, Illinois, Pennsylvania, and Wisconsin, with Mississippi State University appearing as a repeat buyer across multiple solicitations. The high concentration of sole-source university equipment procurements reflects research infrastructure investment rather than a broad market for any single commodity. Without relevant recent activity under this code, business development professionals should treat it as inactive for near-term pursuit.
