UNSPSC 31241812: Polarizing filter

A filter that is used to change the natural light to the polarized light or detect the polarized light. This filter undertakes the role to minimize the reflection.

UNSPSC 31241812 Polarizing filter is a Commodity code that captures optical filtering and lens accessories used in microscopy, laboratory instrumentation, and related scientific equipment across state and local procurement. State and local governments buy these products primarily as components within broader microscope and optical-equipment packages supporting educational institutions, public health laboratories, and research facilities. The issuing bodies soliciting under this code span state procurement offices (notably the Texas Comptroller of Public Accounts and the State of Michigan) and, through cooperative purchasing vehicles, the school districts and laboratory agencies that participate in statewide agreements. Polarizing filters and related optical accessories are typically procured as line items within larger microscope and equipment specifications, often bundled with other optical components to meet institutional laboratory standards.

Recent activity shows solicitations concentrated in Texas and Michigan. The Texas Comptroller of Public Accounts posted a cooperative purchasing notice (304T27490M2) on August 5, 2026, for microscopes and accessories through the Texas Cooperative Purchasing Network (TCPN), an indefinite-quantity, requirements-type vehicle enabling multiple state and local agencies to purchase at pre-negotiated fixed unit costs; proposals were due September 1, 2026, with a 120-day response period following that deadline. The State of Michigan issued a Notice of Intent for RFP 250000002612 on July 27, 2026 (due July 31, 2026), regarding optical lenses and frames, though the full scope and evaluation details were not disclosed in the available synopsis. Both opportunities reflect the use of statewide cooperative purchasing and RFP structures to consolidate laboratory equipment procurement across multiple participating entities, with pricing structured to leverage volume and standardize optical component specifications across the education and laboratory procurement base.
