UNSPSC 60104821: Photoelectric effect apparatus

A device used to test the photoelectric effect through the process when electrons are emitted from the surface of matter via the photoelectric effect from phototubes, the current that emits from the opposite side is measured.

UNSPSC 60104821 Photoelectric effect apparatus is a Commodity code that in recent state and local activity bears little relevance to its nominal scope. The recent opportunities posted under this code do not align with photoelectric equipment or apparatus; instead, they reflect school district procurement for teaching and instructional materials, science supplies, and STEM educational products. Harlingen Consolidated Independent School District solicited reading and video materials (IFB CRDG1026, due October 1, 2026), while Cobb County School District in Georgia posted an IFB for science specimens, chemicals, supplies, and equipment serving 112 school sites and 105,738 students (IFB B26128, due June 16, 2026, estimated annual spend $175,000). Katy Independent School District in Harris County, Texas issued a supplemental RFP for comprehensive instructional materials across English Language Arts, Mathematics, Reading, Science, Social Studies, Health/Physical Education, and Arts & Crafts, along with special education supplies, assistive technology, and miscellaneous items including 3D printers and robotics equipment (RFP 2428KD-A, due May 29, 2026, contract term through October 22, 2027 with options to renew annually through 2030). The School Board of Seminole County, Florida also posted a sole-source procurement for five tonnes of Anorthosite Highlands Simulant from Space Resource Technologies for the ePathways Department (approximate annual expenditure $20,000).

Recent activity concentrates in Texas and Georgia school districts, with single opportunities in Florida and Arizona. Cartwright Elementary School District No. 83 in Arizona, on behalf of the SAVE consortium spanning multiple Arizona school districts, municipalities, counties, and higher education institutions, issued RFP 260331 for STEM and College & Career Readiness Kits, Programs & Materials (due June 8, 2026, survey data from fifteen participating districts indicates estimated annual usage of $1,346,000). The code shows no pattern of photoelectric equipment procurement among state and local buyers. The mismatch between the code's nominal scope and actual recent activity suggests the code assignment may be erroneous or that photoelectric apparatus represents a negligible portion of state and local spending under this designation.
