UNSPSC 41104509: Vacuum ovens

UNSPSC 41104509 Vacuum ovens, a Commodity code, covers laboratory and testing ovens and furnaces procured by state departments of transportation for materials and asphalt testing. Recent state and local opportunities show actual procurement spanning digital convection ovens with forced-air circulation, NCAT asphalt content furnaces for ignition burn-off testing to ASTM and AASHTO standards, and mechanical convection ovens with precise temperature control. State transportation departments dominate the issuing-body mix; TxDOT (Texas Department of Transportation) and IDOT (Illinois Department of Transportation) appear repeatedly as repeat buyers. All recent solicitations follow standard IFB or competitive bid processes through state procurement portals (Bonfire/Euna for Texas, direct submission for Illinois). Equipment specifications emphasize stainless steel interiors, digital temperature controllers with PID control or equivalent, forced-air circulation, UL listing or nationally recognized laboratory certification, temperature uniformity within tight tolerances (typically 0.3 to 2.5 degrees Celsius), and operating ranges from ambient plus 15 degrees Celsius to 300 degrees Celsius or higher. Vendors must meet state prequalification requirements—TxDOT requires registration on the Centralized Master Bidders List (CMBL) and the Euna Procurement portal, while IDOT requires compliance with prevailing wage, non-expatriation certification, and equal opportunity standards. TxDOT applies Texas procurement preferences including preferences for Texas-produced supplies, USA-produced equipment, and service-disabled veteran-owned businesses.

Recent opportunities concentrate in Texas and Illinois. TxDOT Abilene District posted IFB 601340000066830 (posted July 23, 2026, due August 6, 2026) for two 10.6-cubic-foot digital ovens and three NCAT asphalt furnaces with 12-month warranties; TxDOT also posted mechanical convection oven IFB 601340000066612 for the Childress District (posted July 2, 2026, due July 23, 2026) and IFB 601340000066278 for laboratory ovens and NCAT furnaces for the Abilene District (posted June 22, 2026, due July 13, 2026). IDOT District 6 posted rebid IFB 27494DOTFINADB52856 (posted June 15, 2026, due June 25, 2026) for a 28-cubic-foot forced air oven with single-phase 230-volt power, and earlier IFB 26494DOTFINADB52235 (posted May 4, 2026, due May 8, 2026) for an identical 28-cubic-foot unit. Delivery locations are specified in each solicitation; TxDOT specifies Abilene, and IDOT specifies Springfield, Illinois at 2420 South Dirksen Parkway. Insurance and compliance requirements vary by state; Illinois requires $1 million general liability per occurrence and $2 million annual aggregate.
