UNSPSC 60104512: Milikans oil drop apparatus

Instruments used to calculate the quantity of electric charge using the gravity and electric power that influences the electron, which was designed by Robert Milikan

UNSPSC 60104512 Milikan's oil drop apparatus (Commodity) does not align with recent state and local procurement activity. The code nominally describes a physics laboratory instrument used to measure the elementary electric charge, yet the recent opportunities tagged under this code overwhelmingly solicit comprehensive educational materials, supplies, and services spanning instructional resources, STEM equipment, classroom technology, and science consumables—none of which are specifically physics demonstration apparatus. The mismatch suggests either classification drift in the procurement system or that sourcing bodies are using this code as a catch-all for science education procurement without precision to the commodity level.

Activity in the opportunities block centers on school districts and educational consortiums across Texas, Georgia, and Florida procuring general science supplies and broad instructional materials rather than specialized physics lab equipment. Katy Independent School District (Texas) issued RFP #2428KD-A in May 2026 for teaching and instructional materials across multiple subjects including science; Cobb County School District (Georgia) published IFB B26128 in June 2026 for science specimens, chemicals, supplies, and general equipment; and Donna Independent School District (Texas) solicited science supplies catalog bids in April 2026. Cartwright Elementary School District (Arizona) also issued RFP 260331 through the SAVE consortium for STEM and College & Career Readiness kits and materials. The geographic concentration spans Texas school districts (Katy, Donna, Los Fresnos), Georgia districts (Cobb County, DeKalb), and Florida entities (Seminole County, Valencia College), with activity also in Arizona through multi-jurisdictional cooperative purchasing. None of the recent solicitations reference Milikan apparatus, oil drop experiments, or the specific physics measurement application the code describes, indicating limited actionable pursuit potential under this code designation.
