UNSPSC 41111721: Transmission electron microscopes

UNSPSC 41111721 Transmission electron microscopes (Commodity) covers analytical and inspection microscopy systems that state and local governments buy for research, quality assurance, and materials testing — though recent solicitations reveal that the code is being applied to scanning electron microscope (SEM) detector systems and benchtop SEM units rather than transmission electron microscopes per se. The Texas Department of Transportation is soliciting Energy Dispersive Spectroscopy and Electron Backscatter Diffraction detector systems for elemental and crystallographic analysis of materials samples; Texas A&M University is seeking a benchtop SEM; and the Texas Comptroller of Public Accounts is aggregating microscope equipment and accessories through a cooperative purchasing network serving multiple state and local agencies across the education and laboratory base. Issuing bodies include state transportation and higher-education departments, state purchasing offices managing cooperative vehicles, and individual public universities.

Activity is concentrated in Texas, with three recent solicitations posted between July and August 2026. The Texas Department of Transportation issued IFB 601440000052880 for two SEM detector systems (Energy Dispersive Spectroscopy and Electron Backscatter Diffraction), with bids due August 28, 2026 and award tentatively set for August 31, 2026; pricing specifies Oxford Instruments models, though equivalents meeting or exceeding specifications are considered, and includes furnishing, delivery, installation, calibration, on-site training, and one-year preventive maintenance with optional renewals through August 31, 2027. Texas A&M University issued ITB 26-5068 for a benchtop scanning electron microscope with bids due July 29, 2026 through the AggieBid platform. The Texas Comptroller of Public Accounts issued an indefinite-quantity, requirements-type cooperative purchasing agreement (Requisition 304T-27-490M2) for microscopes and accessories open to multiple Texas state and local agencies, with proposals due September 1, 2026 and pricing firm-fixed across participating entities.
