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 Milikans oil drop apparatus is a Commodity code, but the recent state and local opportunities posted under this code show no activity purchasing Milikan oil drop apparatus or related physics demonstration equipment. Instead, the tagged solicitations cover reading and video materials for school libraries, comprehensive teaching and instructional supplies across multiple subject areas, STEM and college readiness kits, science lab supplies and chemicals, and a sole-source procurement for lunar regolith simulant for educational use. The code designation appears misaligned with actual purchasing activity. State and local governments do buy instructional science equipment and materials under related codes, but this specific Commodity code does not reflect the buying pattern shown in recent postings.

The recent opportunities originate from independent school districts in Texas (Harlingen Consolidated ISD, Katy ISD), Arizona (Cartwright Elementary School District via the SAVE cooperative consortium), Georgia (Cobb County School District), and Florida (Seminole County Schools). The buying bodies are exclusively K–12 school districts and their affiliated purchasing cooperatives, with no state department or municipal procurement activity visible in the recent record. Katy ISD appears twice as a repeat buyer, issuing both an initial RFP and a supplemental solicitation (RFP #2428KD-A) for teaching and instructional materials through May 2026. Cobb County School District's science supplies procurement (IFB B26128, due June 16, 2026) targets all 112 school sites serving 105,738 students and requires vendors to establish online ordering, accept procurement cards, deliver within ten business days, and maintain an assigned account representative, with an estimated annual expenditure of $175,000. Because the Commodity code itself does not match the work actually being solicited, this code warrants monitoring rather than active pursuit unless a reclassification occurs in future postings.
