UNSPSC 60104928: Crookes tube

A discharge tube with level of vacuum of less than 0.1mmHg of pressure, and is also referred to as vacuum discharge tube.

UNSPSC 60104928 Crookes tube is a Commodity code that shows no meaningful alignment with recent state and local procurement activity. The code nominally describes a specialized vacuum tube device, but the recent opportunities tagged under it instead solicit teaching and instructional materials, STEM kits, science supplies, and reading and video materials for school districts. Harlingen Consolidated Independent School District posted solicitation CRDG1026 for reading and video materials with a response deadline of October 1, 2026, while the School Board of Seminole County, Florida undertook a sole-source procurement for Anorthosite Highlands Simulant under notice 25260122SVG—neither of which relate to Crookes tubes or vacuum tube equipment. The issuing bodies are school districts and county school boards, but the work actually being procured falls outside the code's nominal scope.

Katy Independent School District in Texas issued RFP 2428KD-A for teaching and instructional materials, supplies, equipment, and services across multiple campuses with a contract term running through October 22, 2027 and renewable for up to three additional years. Cobb County School District in Marietta, Georgia posted IFB B26128 on May 15, 2026 for science specimens, chemicals, supplies, and equipment serving all 112 school sites with an estimated annual expenditure of $175,000 and responses due June 16, 2026. Cartwright Elementary School District No. 83, on behalf of the SAVE consortium in Arizona, issued RFP260331 for STEM and College & Career Readiness kits and materials with survey data indicating estimated annual usage of $1,346,000 across fifteen participating districts and a response deadline of June 8, 2026. The code shows limited recent relevant activity; procurement professionals should verify whether their Crookes tube or vacuum tube product offerings genuinely fit the educational materials and supplies categories these school districts are actually buying.
