UNSPSC 41104501: Laboratory mechanical convection ovens

UNSPSC 41104501 Laboratory mechanical convection ovens, a Commodity code, describes equipment that state and local transportation and materials-testing laboratories procure for asphalt content analysis, thermal uniformity testing, and materials science work. Recent solicitations show state transportation departments buying forced-air and mechanical convection laboratory ovens with specifications ranging from 10.6 to 28 cubic feet, digital temperature control systems (PID or equivalent), stainless steel interiors, temperature ranges from ambient plus 15 degrees Celsius to 300–450 degrees Fahrenheit, and tight uniformity and stability tolerances. The Texas Department of Transportation and Illinois Department of Transportation are the primary issuing bodies under this code, both procuring equipment for district-level materials laboratories. These are typically IFB solicitations with firm, fixed-price bidding through state procurement portals (Euna/Bonfire for TxDOT; directly through IDOT) and standard state terms including prevailing wage, insurance, and vendor registration requirements (CMBL in Texas).

Recent activity concentrates in Texas and Illinois. TxDOT posted at least three opportunities between June and July 2026: Solicitation 601340000066830 (Abilene District, IFB due August 6, 2026) sought two units of a 10.6-cubic-foot Gilson Model BO-355ERS oven with Watlow digital control, three NCAT Asphalt Content Furnaces, and three furnace starter kits, requiring delivery to Abilene and 15 consecutive failure-free operational days post-installation; Solicitation 601340000066278 (Abilene District, due July 13, 2026) covered similar laboratory ovens and asphalt furnaces; and Solicitation 601310000101248 (due May 4, 2026) solicited a forced convection oven with minimal publicly disclosed detail. Illinois Department of Transportation District 6 posted two near-identical rebids for a 28 cubic foot forced air laboratory oven (Solicitation 27494DOTFINADB52856, due June 25, 2026, and Solicitation 26494DOTFINADB52235, due May 8, 2026), each requiring stainless steel construction, 230-volt single-phase power, and delivery to Springfield. Vendors must register on state bidder lists (CMBL for Texas, standard registration for Illinois) and comply with each state's terms, including Texas transportation procurement preferences for Texas-produced supplies and service-disabled veteran-owned businesses where applicable.
