UNSPSC 41113337: Dispersion or grain size tester

A tester that evaluates and tests the dispersion, cohesion, and safety of disperse system like colloid.

UNSPSC 41113337 Dispersion or grain size tester is a Commodity code covering laboratory and quality-control instruments that measure particle size distribution and dispersion characteristics in materials. State and local governments procure these testers primarily through state environmental and transportation departments, university research facilities, and municipal public works agencies conducting materials testing, asphalt and concrete quality assurance, soil analysis, and regulatory compliance work. The instruments support infrastructure construction oversight, environmental monitoring, and materials science applications where precise grain size classification directly affects design specifications and performance standards.

The source contains no recent state or local contract opportunities tagged to this code, making it difficult to characterize current issuing-body concentration, geographic activity, or representative recent solicitations. This silence may reflect either genuine procurement inactivity under the code or misalignment between how state and local buyers classify these instruments in their taxonomies and the UNSPSC categorization itself. Firms pursuing this equipment space should monitor state DOT material-testing RFPs, university capital equipment RFQs, and municipal water and environmental quality contracts where grain-size analysis drives specification or acceptance testing.
