UNSPSC 60104921: Zeeman effect apparatus

A device used to experiment Zeeman effect, the splitting of a spectral line into several components in the presence of a static magnetic field caused by the electric spin.

UNSPSC 60104921 Zeeman effect apparatus (Commodity) shows minimal recent state and local procurement activity aligned with its nominal scope. The code's technical definition — specialized physics laboratory equipment for demonstrating the Zeeman effect — does not appear in the recent opportunities tagged under it. Instead, the most recent postings reflect elementary and secondary school districts soliciting general reading materials, instructional supplies, STEM kits, and science lab consumables (specimens, chemicals, equipment) that fall outside the apparatus category. The mismatch signals either a data-entry error in code assignment or a state and local taxonomy that conflates laboratory science supplies more broadly under this commodity code.

Activity in the recent opportunities block centers on Texas and Georgia school districts issuing RFPs and IFBs for instructional materials and science supplies — Harlingen Consolidated Independent School District (reading and video materials, due October 1, 2026), Katy Independent School District (teaching and instructional materials, RFP #2428KD-A, due May 29, 2026), Cobb County School District in Georgia (science supplies IFB B26128, due June 16, 2026), and Cartwright Elementary School District No. 83 in Arizona on behalf of the SAVE consortium (STEM and college and career readiness kits, RFP 260331, due June 8, 2026). A single Florida school board posting covers sole-source procurement of lunar regolith simulant from Space Resource Technologies — an outlier unrelated to the code's apparatus definition. The recent opportunities suggest the code is being used as a catch-all for school district science and instructional procurement rather than for discrete laboratory apparatus, making pursuit strategy contingent on clarifying whether your firm's capabilities align with consumables, kits, and general supplies rather than specialized physics equipment.
