Dual Convection Oven - Forced Air Drying Oven - 50-300°C - 42 to 224 L

The Master Science Dual Convection Oven works as a forced-air oven with the fan running, or as a natural convection oven when the fan is switched off. This makes one unit suitable for both fast, even drying and for light powders that must not be disturbed by air flow.

It is used for drying, baking, wax melting and dry-heat sterilisation from 50 to 300 °C. Four chamber sizes are available, from 42 to 224 litres.

Key Benefits

• Two ovens in one: the Master Science Dual Convection Oven switches between forced and natural air flow.
• Choice of heating power: a selector switch matches power to the load.
• See samples without heat loss: inner glass door.
• Safe unattended runs: alarms and power-failure memory.
• High temperature: up to 300 °C for baking and sterilisation.

Common Laboratory Problems and How This Oven Helps

Everyday issues the Master Science Dual Convection Oven addresses:

• Uneven drying: forced air spreads heat through the chamber.
• Light powders blown around: switch the fan off for natural convection.
• Opening the door to check samples: inner glass door keeps heat in.
• Interrupted programs: memory resumes after power returns.
