UNSPSC 31241900: Optical domes

UNSPSC 31241900 Optical domes is a Class code that covers microscopes, optical accessories, and related laboratory equipment that state and local governments procure for educational institutions, laboratory facilities, and research operations. Recent solicitations show state and local buyers acquiring complete microscope systems bundled with supplementary optical components and accessories, rather than dome elements in isolation. Issuing bodies under this code include state procurement offices operating cooperative purchasing vehicles and individual state agencies. The Texas Comptroller of Public Accounts uses the Texas Cooperative Purchasing Network (TCPN) to consolidate microscope and accessories procurement across multiple Texas state and local agencies on an indefinite-quantity, requirements-type agreement basis, enabling participating entities to access pre-negotiated firm fixed-price unit costs.

Activity under the code concentrates in Texas and Michigan based on recent postings. The Texas Comptroller's TCPN solicitation (Requisition 304T-27-490M2, RFP, due September 1, 2026) seeks microscopes and accessories with mandatory price sheets establishing line-item unit pricing for specified microscope products, warranty provisions covering defects and replacement, and compliance certifications including Texas-based vendor and service-disabled veteran preference eligibility. Michigan's State of Michigan issued a Notice of Intent for RFP 250000002612 regarding optical lenses and frames (due July 31, 2026), though the full RFP scope, contract value, and evaluation criteria are not publicly detailed in available summaries. Cooperative purchasing vehicles and state-level indefinite-quantity agreements dominate the procurement structure under this code, with responses remaining in effect for extended periods (120 days post-due-date in the Texas example) to support statewide volume consolidation.
