UNSPSC 41111755: Microscope knob

Knob that is used for coarse and fine vertical adjustment of the objectives and condenser of a microscope, or that is used for the horizontal and vertical adjustment of the microscope stage for optimal viewing of specimens

UNSPSC 41111755 Microscope knob (Commodity) appears in state and local procurement activity focused on complete microscopy systems, accessories, and training services rather than knobs as discrete components. Universities, state agencies, and county governments solicit under this code for FTIR microscopes, comparison microscopes, darkfield optical systems, and trinocular microscopes bundled with objectives, eyepieces, light sources, cameras, workbenches, dust covers, and related accessories. Issuing bodies include research universities (University of Mississippi, Texas Tech University, University of Wisconsin-Madison, Texas A&M AgriLife Research), state forensic laboratories (Illinois State Police), and county water resources departments (Hillsborough County, Florida). The actual procurement pattern shows microscopy equipment as integrated systems rather than component sourcing.

Recent activity spans the South, Midwest, and Great Plains. The University of Mississippi issued an IFB for an FTIR Microscope Micro-sampling and Chemical Imaging System due June 18, 2026. The Illinois State Police issued IFB 26-493ISP-FOREN-B-51686 for comparison microscopes (Leica FS M Stand or LEEDS equivalents) configured across eight forensic laboratories statewide, with delivery, installation, training, and performance verification included, fixed pricing for the contract life, and a three-year initial term with options extending to ten years. Texas A&M AgriLife Research solicited an Enhanced Darkfield Optical Microscope System through ITB AG-RSCH-ITB-6554 (due February 5, 2026). University of Wisconsin-Madison issued RFB 2026-UWMSN-01294-RFB for microscopes, accessories, and maintenance services due April 3, 2026. Hillsborough County Board of County Commissioners issued competitive quote ITQ2600183 for Motic Trinocular Microscope Training (estimated at $21,000.00, due March 19, 2026), requiring DEP-approved, CEU-certified instruction in wastewater microbiology and microorganism identification across two four-day sessions for 30 participants total.
