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 does not map to current state and local procurement activity. The recent opportunities in the source are tagged with this code but describe educational materials, science supplies, classroom technology, and instructional resources—none of which are Crookes tubes or vacuum discharge apparatus. The Katy ISD supplemental RFP (May 29, 2026) covers teaching and instructional materials across multiple disciplines including 3D printers and robotics; the Cobb County IFB B26128 (June 16, 2026) seeks science specimens, chemicals, and general laboratory supplies; the Cartwright Elementary / SAVE consortium RFP (June 8, 2026) procures STEM kits and college-readiness programs; and the DeKalb County RFQ 26-724 (March 12, 2026) targets K-12 science instructional resources aligned with state standards. Donna ISD issued separate catalog bids for science supplies and classroom materials (April 8, 2026), and Savannah-Chatham County Public Schools solicited educational materials across seven categories including science (April 28, 2026). Valencia College pursued classroom technology services (April 30, 2026), and Seminole County Schools posted a sole-source notice for specialized STEM lab equipment from Realityworks (March 2, 2026).

The code shows no genuine recent state and local procurement activity for Crookes tubes, vacuum discharge devices, or related cathode-ray apparatus. The opportunity records appear to be mistagged at the commodity level. School districts and educational institutions across Texas, Georgia, Arizona, and Florida are actively procuring science classroom supplies, educational technology, and STEM instructional materials—but none of these solicitations reference or require Crookes tubes. If you are targeting state and local K-12 or higher-education procurement, the relevant codes lie in general science supplies, instructional materials, and educational equipment categories rather than this specialized commodity code.
