UNSPSC 41104501: Laboratory mechanical convection ovens

UNSPSC 41104501 Laboratory mechanical convection ovens is a Commodity code purchasing the heating equipment state and local governments use for materials testing, quality assurance, and regulatory analysis across transportation, environmental, and public health laboratories. State and local buyers are procuring forced-air and mechanical convection ovens with specified thermal performance, temperature uniformity, digital control systems, and safety certifications (UL listing or equivalent) to support lab workflows in water and wastewater testing, asphalt and materials analysis, and other analytical applications. Issuing bodies include state transportation departments (Texas Department of Transportation, Illinois Department of Transportation), municipal utilities, and county public health agencies. The work is predominantly equipment procurement through IFB notices with detailed technical specifications governing dimensions, power requirements, temperature range, control resolution, and insurance or compliance terms.

Recent activity concentrates in Texas and Illinois. The Texas Department of Transportation Childress District posted an IFB for a mechanical convection oven due July 23, 2026 (solicitation 601340000066612), and the TxDOT Abilene District solicited laboratory ovens and NCAT asphalt furnaces due July 13, 2026 (solicitation 601340000066278), both requiring registration on the Euna Procurement platform and current listing on the Texas Comptroller of Public Accounts Centralized Master Bidders List. The Illinois Department of Transportation District 6 rebid a 28 cubic foot forced air laboratory oven due June 25, 2026 (solicitation 27494DOTFINADB52856), specifying exterior dimensions not exceeding 43 × 35 × 86 inches, single-phase 230-volt 60-Hz power at maximum 50 amps, temperature range from ambient plus 15 degrees Celsius to 300 degrees Celsius minimum, temperature uniformity within 2.5 degrees Celsius, digital PID control with 0.1 degree Celsius resolution, and $1 million per occurrence/$2 million aggregate liability insurance. IDOT District 6 posted an earlier version of the same specification due May 8, 2026 (solicitation 26494DOTFINADB52235). TxDOT also solicited a forced convection oven due May 4, 2026 (solicitation 601310000101248). Vendors must monitor procurement portals for addenda and comply with state standard terms including prevailing wage, non-expatriation certification, and record retention.
