UNSPSC 31241802: Gradient filters

UNSPSC 31241802 Gradient filters is a Commodity code that encompasses optical filter products and related accessories used in laboratory and educational microscopy applications. State and local governments procure gradient filters alongside broader microscope systems and component assemblies to support pathology, biology, research, and diagnostic laboratory work in public health departments, state universities, community colleges, and school district science programs. Recent solicitations show that filter procurement typically occurs as part of larger equipment packages or cooperative purchasing agreements rather than as standalone commodity buys, bundled with microscopes, lenses, and complementary optical accessories to serve institutional laboratory needs.

The Texas Comptroller of Public Accounts is the most recent active issuer, posting requisition 304T27490M2 on August 5, 2026 through the Texas Cooperative Purchasing Network (TCPN) with a response deadline of September 1, 2026. This cooperative purchasing vehicle operates as an indefinite-quantity, requirements-type agreement enabling multiple Texas state and local agencies—including state departments, public universities, community colleges, and school districts—to access pre-negotiated unit costs for microscopes and accessories with firm fixed pricing established in Attachment F. The State of Michigan issued a Notice of Intent for RFP 250000002612 on July 27, 2026 regarding optical lenses and frames, though the underlying solicitation scope, contract value, and evaluation criteria are not disclosed in available summary documents. Texas and Michigan represent the primary recent geographic activity, with the Texas vehicle likely to drive volume across participating state education and laboratory procurement base.
