UNSPSC 41115312: Bench refractometers or polarimeters

UNSPSC 41115312 Bench refractometers or polarimeters, a Commodity code, covers laboratory optical and analytical instruments used in materials science and research applications. State and local procurement under this code spans university research institutions and science departments acquiring specialized analytical equipment — in this case, rheometers and related materials-testing systems that measure polymer properties, viscosity, and thermal behavior. The issuing bodies are primarily higher-education entities, particularly university research centers and polymer institutes that conduct advanced materials science work and require precision instrumentation compatible with existing laboratory infrastructure.

The University of Southern Mississippi is the only recent solicitation activity visible in the opportunities block. USM posted a Notice of Proposed Sole Source Purchase on September 3, 2026 (objections due September 18, 2026) for a Waters/TA Instruments Discovery Hybrid Rheometer HR 30 at a quoted price of $130,271. The procurement is justified as sole-source on grounds of compatibility with existing TA Instruments equipment already operated by the Mississippi Polymer Institute; the notice includes an alternative quote from Anton Parr for comparison and establishes a procedural pathway for competitive conversion if USM determines alternative sources exist. Activity under this code appears limited and episodic, driven by specific laboratory infrastructure requirements and institutional research needs rather than recurring or high-volume demand. Geographic reach is limited to Mississippi based on available solicitations.
