Chamber Furnaces up to 1200°C / 2192°F

Our high quality resistance wire wound ceramic muffle furnace range, comprising the EF, LF and PF, provide excellent uniformity and a hard wearing work surface, providing a durable loading area for work pieces. Vecstar Muffle Furnaces incorporate numerous safety features such as a vertically opening door, keeping the hot insulation door plug away from the operator, automatic shut-off switch that kills the power to the elements whenever the door is opened and a powder coated double steel skin ensuring the outer surface is as cool as possible. Ultra ‘high grade’ insulation materials are used to ensure our muffle 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.

Also available is a wide range of equipment and extras such as digital controllers, programmers, recorders, crucibles, tongs and furnace tables.

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

Our in-house experts and CAD design team are on hand to assist you and will complete your project through consultancy, design, manufacture, installation and ongoing support.

Full training and ongoing support is offered as standard and we promise the best possible service.

Available in the UK, USA and Worldwide directly through Vecstar or through our approved distributors.
