UNSPSC 60104820: Kundt apparatus

An apparatus for experiment in which a bar is vibrated vertically and its wave length is measured through resonance in the glass tube with a view to measuring the velocity of sound in the solid, liquid and air.

UNSPSC 60104820 Kundt apparatus is a Commodity code representing specialized educational laboratory equipment and STEM materials that state and local school districts procure to support science instruction and experiential learning. Recent solicitations show school districts purchasing integrated STEM lab kits, physics and renewable energy demonstration equipment, science specimens and chemicals, and comprehensive science instructional resources aligned with state standards. The issuing bodies are predominantly K-12 school districts of varying sizes, from small independent school districts in Texas to large urban districts serving over 100,000 students, along with school district consortia procuring on behalf of multiple member districts and higher education institutions. Katy Independent School District in Texas and Cobb County School District in Georgia appear as repeat buyers, with both districts soliciting science supplies and instructional materials within the past two months.

Activity concentrates in Texas, Georgia, and Florida, with recent solicitations posted by Donna ISD and Los Fresnos ISD in Texas (March 2026), Cobb County School District and DeKalb County School District in Georgia (February–May 2026), and School Board of Seminole County and Valencia College in Florida (April 2026). Representative opportunities include Katy ISD's RFP #2428KD-A for teaching and instructional materials, supplies, equipment, and services across multiple campuses with proposals due May 29, 2026; Cobb County School District's IFB B26128 for science specimens, chemicals, supplies, and equipment serving 112 schools with bids due June 16, 2026; and Cartwright Elementary School District's RFP 260331 on behalf of the SAVE consortium for STEM and College & Career Readiness Kits, Programs & Materials across multiple Arizona jurisdictions with proposals due June 8, 2026. School districts typically structure these procurements as RFPs or IFBs with discount-from-catalog pricing models, award to multiple vendors to allow schools flexibility in vendor selection, and as-needed purchasing with no guaranteed minimum volumes. Contracts commonly run one to three years with renewal options and require vendors to maintain online ordering platforms, accept purchase orders and procurement cards, deliver within 10 business days, and provide inside delivery to school sites at no additional cost.
