UNSPSC 60104922: Coulombs law apparatus

Equipment to experiment the Coulomb's Law that force acting between 2 small electrified bodies is proportional to 2-times the quantity of electric charges, and reversely proportional to the square of distance between these 2 bodies.

UNSPSC 60104922 Coulomb's law apparatus (Commodity) shows minimal relevant recent activity under state and local procurement. The code's nominal scope—laboratory physics equipment for demonstrating electrostatic principles—does not align with the recent opportunities tagged to it. The opportunities actually solicited under this code span reading and video materials, teaching and instructional materials across multiple subject areas, STEM and college & career readiness kits, science supplies and specimens, and anorthosite highlands simulant for research purposes. These solicitations fall across multiple UNSPSC families and do not focus on Coulomb's law apparatus or similar specialized physics demonstration equipment. State and local issuing bodies posting under this code include independent school districts (Harlingen Consolidated ISD, Katy ISD in Harris County Texas, Cartwright Elementary School District No. 83 in Arizona acting on behalf of the SAVE consortium, and Cobb County School District in Marietta Georgia) and a county school board (Seminole County Schools in Florida). The mix reflects school district purchasing across instructional materials broadly rather than discrete equipment categories.

Geographic activity centers on Texas (Harlingen and Katy), Arizona (Cartwright on behalf of multiple participating districts), Florida (Seminole County), and Georgia (Cobb County). Representative recent opportunities include Katy ISD's RFP #2428KD-A for teaching and instructional materials, supplies, equipment, and services with proposals due May 29, 2026, covering a comprehensive range including general instruction materials, special education supplies, ESL materials, and miscellaneous items with an initial contract term through October 22, 2027 and renewal options through October 23, 2030; Cobb County School District's IFB B26128 for science specimens, chemicals, supplies, and equipment for all 112 school sites with responses due June 16, 2026, with an estimated annual expenditure of $175,000; and Cartwright Elementary School District's RFP 260331 on behalf of SAVE for STEM and college & career readiness kits, programs, and materials for multiple Arizona school districts and municipalities with proposals due June 8, 2026, reflecting estimated annual usage across participating districts of $1,346,000. The code appears underutilized for its intended commodity scope; recent procurement activity tagged to it does not reflect specialized physics laboratory equipment purchases.
