Ashing furnaces

When ashing materials a good airflow through the chamber is essential for complete combustion. We ensure this with a 50mm bore chimney, 610mm high which gives the required air flow. Air is drawn through inlets in the back of the furnace under the hearth tile, being pre-heated before entering the chamber, passing over the samples and travelling up the chimney.


Our Ashing Furnace range incorporates numerous safety features such as a vertically opening door to keep the hot insulation plug away from the operator, automatic shut-off switch that kills the power to the elements when the door is opened and a double steel skin ensuring the outer surface is as cool as possible. Ultra ‘high grade’ insulation materials are used to ensure our furnaces are as energy efficient as possible.

Independent over-temperature protection is available as an option, using a digital alarm working from a separate thermocouple, safeguarding both the furnace or any furnace contents from over-heat damage at any temperature.

Our Ashing Furnace range is supported by a wide range of equipment and extras such as crucibles, tongs and furnace tables.

Detailed here are our two standard Ashing Furnaces. We design and build in house so if you have a bespoke requirement please do not hesitate to contact us.
