UNSPSC 60104818: Planck constant apparatus

A device used to measure the Plank constant, the proportionality constant between energy of a photon and the frequency of its associated electromagnetic wave.

UNSPSC 60104818 Planck constant apparatus (Commodity) shows little relevant recent activity. The eight state and local solicitations tagged with this code are all education-sector purchasing for science and classroom instruction materials — science supplies, STEM kits, instructional resources, classroom technology, and general educational materials — none of which align with laboratory apparatus for physics education at the commodity level. Katy Independent School District in Texas issued RFP #2428KD-A for teaching and instructional materials with a May 29, 2026 deadline; Cobb County School District in Georgia posted IFB B26128 for science specimens, chemicals, and supplies due June 16, 2026; Cartwright Elementary School District No. 83 in Arizona solicited STEM and College & Career Readiness kits via RFP (due June 8, 2026) on behalf of the SAVE cooperative purchasing consortium serving multiple districts and municipalities; Valencia College District in Florida issued RFP 2026-26 for classroom and conference room technology services (due April 30, 2026); and Seminole County Schools in Florida pursued a sole-source acquisition for Realityworks STEM lab equipment (March 2, 2026). Additional opportunities came from Savannah-Chatham County Public Schools in Georgia (RFP 26-35, educational materials catalog discounts, due April 28, 2026), Donna ISD in Texas (two catalog bids for science supplies and classroom materials, both due April 8, 2026), Los Fresnos CISD in Texas (RFP #26-27-04 for general merchandise and school products, due March 31, 2026), and DeKalb County Schools in Georgia (RFQ 26-724 for science instructional resources, due March 12, 2026).

The issuing bodies represent independent school districts, county school systems, and a college district concentrated in Texas, Georgia, Arizona, and Florida, with opportunities spanning K-12 and higher education. Geographic activity clusters in Texas (Katy ISD, Donna ISD, Los Fresnos CISD) and Georgia (Cobb County, Savannah-Chatham, DeKalb), with secondary activity in Arizona (Cartwright/SAVE consortium) and Florida (Valencia College, Seminole County). The code's nominal definition — Planck constant apparatus — does not match the solicitation scope, and the tagged opportunities do not reference specialized physics laboratory equipment, instrumentation, or apparatus procurement. Vendors pursuing this code should verify that their actual products align with education-sector science and instructional materials before engaging; the mismatch between code definition and recent buying activity suggests either miscoding in the source data or a code tier that does not reflect current state and local procurement patterns in this category.
