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, a Commodity code, has no recent state and local procurement activity aligned with its nominal scope. The source records ten recent school district solicitations spanning teaching and instructional materials, STEM and college-readiness kits, science supplies, classroom technology services, and educational resources, but none name or specifically solicit Zeeman effect apparatus or similar laboratory physics equipment. The most specific physics-adjacent opportunity—Seminole County Schools' sole-source acquisition of Realityworks DataSnap STEM labs (motion sensors, air racer, impact, and projectile labs) for approximately $32,118.00—targets hands-on physics demonstration and measurement but does not reference Zeeman effect instrumentation. Katy ISD's supplemental RFP for teaching and instructional materials, Cobb County School District's science supplies bid, Savannah-Chatham County's educational materials catalog discount RFP, and DeKalb County Schools' K-12 science instructional resources procurement all solicit broad science consumables and classroom materials, not specialized laboratory apparatus. The code shows no current market signal among state and local buyers.

School districts and school systems are the exclusive issuing bodies in the identified opportunities, concentrated in Texas (Katy ISD, Donna ISD, Los Fresnos CISD), Georgia (Cobb County Schools, Savannah-Chatham County Schools, DeKalb County Schools), Florida (Seminole County Schools, Valencia College District), and Arizona (Cartwright Elementary School District through the SAVE consortium). Recent activity spans February through July 2026, with response deadlines ranging from March 2 through June 16. Without solicitations explicitly requesting Zeeman effect apparatus or similar specialized physics laboratory instrumentation, the code presents no actionable pursuit opportunity in state and local procurement at this time.
