Forced Air Drying Oven - Laboratory Convection Oven - 30L to 640L - RT+10 to 250°C, PID LCD

The Master Science Forced Air Drying Oven is a convection oven for drying, baking, wax melting and sterilization in laboratories, research institutions and industrial plants. Five chamber sizes from 30 L to 640 L cover everything from small sample batches to bulky loads.

A high-quality fan with a large impeller draws air from the back and circulates it along both sides, while perforated shelves improve airflow for good temperature uniformity. PID control from ambient +10°C to 250°C, a large LCD menu and a 1 to 9999 minute timer make the Master Science Forced Air Drying Oven quick to set up for routine work.

Problems the Master Science Forced Air Drying Oven Solves

Natural convection ovens can dry unevenly and slowly. The Master Science Forced Air Drying Oven helps with:

• Hot and cold spots: Forced air circulation improves uniformity.
• Long drying times: Active airflow removes moisture faster.
• Wasted energy: Silicone seals and adaptive heating cut losses.
• Overheating risk: Audible and visual over-temperature alarms.
