UNSPSC 60104920 Cloud chamber is a Commodity code that captures laboratory and educational science equipment, though the recent opportunities posted under this code show limited alignment with the nominal category—state and local governments do use it to solicit teaching and instructional materials broadly, including science supplies, specimens, chemicals, and equipment for K–12 instruction. The issuing bodies are predominantly school districts procuring consumables and equipment for science laboratories and classroom instruction, with one sole-source procurement by a school board for a specialized lunar soil simulant. School districts dominate the activity, ranging from small independent districts to large consolidated systems serving over 100,000 students.
