Bench Top Oven

Compare BENCHTOP OVEN or BENCH TOP OVENS for use in the laboratory. Bench top or benchtop ovens are designed to be placed on a laboratory bench or on a shelf. The typical benchtop or bench top oven applications for these ovens are general heating, drying, stability testing, hardening, and sterilizing.

Laboratory bench top ovens differ from industrial bench top ovens in that the laboratory ovens have a cleaner outside finish. Bench top ovens have stainless steel interiors and  two shelves as standard equipment.  They often have enameled exteriors. The size of the ovens ranges from 0.5 cubic feet (14 L) to 50 cubic feet (1400 L). The most common oven sizes are in the 15 (425 L) cubic foot to 27 cubic foot (750 L) range.  The maximum temperature for most bench top ovens is between 200 C (400 F) and 400 C (750 F), but some have a higher maximum temperature. The temperature may be controlled by a simple hydraulic bulb,  a digital microprocessor, or an analog or electronic controller.

Bench top ovens use either natural air convection or forced air. Natural air convection ovens, also called gravity convection ovens, have an opening at the top to allow the expanding air to escape. In a natural air convection oven, there will be a slow air flow from the bottom of the oven to the top due to the convection currents in the oven. Forced air ovens, or circulating air ovens, have a fan with baffles    in the back of the unit to  direct the air to flow vertically or horizontally through the oven.
