The ELF range bench-mounted with a maximum temperature of 1100°C and is available with chamber capacities of 6 and 14 litres. These furnaces are suitable for light duty general laboratory work.
The heating chamber is insulated with vacuum-formed low thermal mass insulation, which offers exceptional performance in achieving maximum temperature quickly and efficiently. A temperature of 1000°C is achieved in as little as 35 minutes. Semi-embedded free radiating wire wound elements are located on the two side walls - elements are not positioned in the hearth. A hard ceramic hearth is fitted as standard, which offers additional protection from spillage.
The drop down door can be used as a shelf when loading and unloading samples. The door insulation also acts as a trap for radiated heat, thus improving the chamber uniformity, whilst the air gap behind the plug minimises the external door temperature.
A ceramic chimney is fitted for ventilation of the chamber, but is not suitable for smoke/fume extraction.
If large volumes of fumes are to be generated by an ashing process, then a model from our dedicated ashing furnace range should be considered.
The digital Carbolite 201 PID controller is fitted as standard and has an adjustable single ramp to set point, as well as an in-built timer which allows for a delayed start or a fixed process duration.
