Most operate on electric heat, but Gilson has several models that operate on LP or natural gas supplies.

The two broad categories of airflow convection for Laboratory Ovens are gravity and forced-air. Forced-air ovens use internal fans to circulate air in the chamber, have better temperature uniformity, and are more efficient at removing moisture from samples. Gravity convection ovens depend on thermal air flow to distribute heat, and can have some variable temperature zones. Majority of the types of oven listed below have Forced-Air except a select few of Lab Ovens and the Peerless Gas Oven.

Temperature range, chamber capacity, and gravity or forced-air convection are the most important factors to consider when selecting the best Laboratory Oven for your application. It is also important to select a cabinet size that fits in the intended space, whether it is a benchtop oven or a high-capacity floor model

The Cox Rolling Thin Film Oven (RTFO) and Superpave Heavy Duty Oven are specialty ovens designed to work with asphalt sample testing. The RTFO mimics short-term maturity of asphalt binders that take place during mixing and laying of hot-mix asphalt.  The Superpave Oven meets all requirements for lab testing of Superpave mix designs.
