UNSPSC 41111741: Microscope differential interference contrast equipment

Equipment that uses the interference effect of light to display the object shown on plane to show the sense of dimension with the height by installing the prism corresponding to each multi-ratio of the objective lens on the condenser.

UNSPSC 41111741 Microscope differential interference contrast equipment, a Commodity code, covers specialized optical microscopy systems and related accessories that state and local governments—chiefly research universities—purchase to support laboratory operations, forensic science, and research initiatives. Recent solicitations show buyers acquiring differential interference contrast microscopes, comparison microscopes for forensic analysis, enhanced darkfield optical systems, and comprehensive training and maintenance services bundled with equipment. The issuing bodies are predominantly higher-education institutions: the University of Mississippi, University of Wisconsin-Madison, and Texas A&M University AgriLife Research posted sealed-bid and RFB procurements for microscope equipment and ancillary services. The Illinois State Police, a law-enforcement agency, solicited comparison microscopes configured across multiple forensic laboratories statewide. A county water resources department (Hillsborough County, Florida) sought training services on Motic Trinocular microscope systems.

Geographic activity concentrates in the South and Midwest. Texas (Texas Tech University and Texas A&M AgriLife Research), Illinois (Illinois State Police), Mississippi (University of Mississippi), Wisconsin (University of Wisconsin-Madison), and Florida (Hillsborough County) account for recent solicitations posted between February and June 2026. Representative opportunities include the Illinois State Police IFB 26-493ISP-FOREN-B-51686, due June 18, 2026, requesting comparison microscopes with accessories and delivery/installation/training across eight forensic labs statewide under a three- to ten-year contract; the University of Mississippi sealed-bid for an FTIR Microscope Micro-sampling and Chemical Imaging System (Bid 1279), due June 18, 2026; Texas Tech University's RFP 2026-1190 for laboratory equipment including microscope systems, evaluated on best value with a twenty-four-month firm-pricing term and up to four one-year renewal options; and the Hillsborough County competitive quote ITQ2600183 for Motic Trinocular Microscope Training at an estimated project value of $21,000, due March 19, 2026.
