UNSPSC 41104507: Laboratory microwave ovens

UNSPSC 41104507 Laboratory microwave ovens is a Commodity code that in practice covers laboratory convection ovens and asphalt testing furnaces procured by state transportation departments for materials and pavement testing. State and local solicitations under this code are requesting forced-air and mechanical convection ovens with precise temperature control, stainless steel construction, and specialized burn-off furnaces for asphalt content testing to ASTM standards. The Texas Department of Transportation and Illinois Department of Transportation are the primary recent buyers, issuing competitive IFB notices for equipment to support laboratory operations at regional districts and testing facilities. Specifications typically call for digital temperature controllers with narrow uniformity and stability tolerances, UL listing or equivalent third-party certification, and single-phase or three-phase electrical power integration.

Recent activity concentrates in Texas and Illinois. The Texas Department of Transportation posted three solicitations between May and July 2026 — IFB 601340000066830 (Laboratory Ovens and Furnaces for the Abilene District, due August 6, 2026), a mechanical convection oven for the Childress District (due July 23, 2026), and a forced convection oven (due May 4, 2026) — all requiring vendor registration on the Euna Procurement portal and the Texas Comptroller's Centralized Master Bidders List. The Abilene solicitation specifies two 10.6-cubic-foot digital ovens with forced-air convection at 450 degrees Fahrenheit maximum, three NCAT Asphalt Content Furnaces meeting ASTM D6307 and AASHTO T308 standards, and three furnace starter kits, with Texas preferences for Texas-produced supplies, USA-produced equipment, and service-disabled veteran-owned businesses. Illinois Department of Transportation District 6 issued two successive bids for a 28 cubic foot forced-air laboratory oven (FY26 solicitation posted May 4, 2026, due May 8, 2026, and FY27 rebid posted June 15, 2026, due June 25, 2026), each requiring 230-volt single-phase power, stainless steel interior, temperature uniformity within 2.5 degrees Celsius, and delivery to 2420 South Dirksen Parkway, Springfield, Illinois.
