UNSPSC 41104507: Laboratory microwave ovens

UNSPSC 41104507 Laboratory microware ovens (Commodity) covers forced-air and mechanical convection laboratory ovens procured by state departments of transportation for field materials testing, particularly asphalt and soil analysis. State and local governments buy equipment meeting narrow technical specifications—units typically 27–28 cubic feet, stainless steel interiors, single-phase 230-volt power, temperature uniformity within 2.5 degrees Celsius, and UL certification—rather than consumer or clinical microwave equipment. The issuing bodies are exclusively state transportation agencies; repeat buyers include the Texas Department of Transportation (TxDOT) and Illinois Department of Transportation (IDOT). Solicitations require vendors to register on state procurement platforms such as Euna (Bonfire) and state centralized vendor lists; TxDOT mandates registration on the Texas Comptroller of Public Accounts Centralized Master Bidders List (CMBL), while IDOT requires compliance with Illinois Standard Terms and Conditions governing prevailing wage, non-expatriation certification, equal opportunity compliance, and record retention.

Activity concentrates in Texas and Illinois. TxDOT's Childress District posted a bid for a mechanical convection oven due July 23, 2026 (Solicitation 601340000066612), and the Abilene District solicited laboratory ovens and NCAT asphalt furnaces due July 13, 2026 (Solicitation 601340000066278, RFQ on the Euna platform). IDOT District 6 has posted two competitive solicitations for 28 cubic foot forced-air ovens with identical specifications: one in June 2026 due June 25, 2026 (Solicitation 27494DOTFINADB52856, rebid), and an earlier FY26 round posted May 4, 2026, due May 8, 2026 (Solicitation 26494DOTFINADB52235). A May 2026 TxDOT solicitation for horizontal airflow cabinet ovens (Solicitation 601310000101248) also registered under this code. Vendors should anticipate standard state procurement compliance timelines and verify current vendor registration status before bid submission deadlines.
