Product information "Nabertherm Muffle Furnace LE 1/11/R8, 1 l, Tmax 1,100 °C, Flap Door, LE015K1A8"
With only 1 litre of usable volume and a weight of 15 kg, the Nabertherm muffle furnace LE 1/11 is the smallest version in the economy series up to 1,100 °C. The heating elements are protected in quartz glass tubes on two sides of the furnace chamber, and the housing is double-walled, made of textured stainless steel sheet, and coated in RAL 9003.
Dimensions and installation
Inside, the usable space measures 90 x 115 x 110 mm (W x D x H), externally the LE 1/11 measures 310 x 300 x 410 mm. The controller is located space-savingly under the flap door, dimensions and weight are kept compact. The flap door can additionally be used as a shelf as long as it is open. On the laboratory bench, the LE 1/11 occupies a footprint of 310 x 300 mm.
Heating elements and heating rate
The quartz glass tubes protect the heating elements on both heated sides. The LE 1/11 operates single-phase with a connected load of 1.6 kW and reaches Tmax minus 100 K, i.e. 1,000 °C, in around 6 minutes when empty and closed. The muffle furnaces with brick insulation require around 55 to 60 minutes to reach their target value of 1,200 °C.
Controller R8
As standard, the LE 1/11 is equipped with the controller R8, which can be set to one temperature. Via NTLog Basic, process data can be recorded directly onto a USB stick. It is located space-savingly under the door.
Exhaust air and service
The exhaust air leaves the furnace via an opening in the rear wall. An exhaust chimney is available as an option only from the LE 6/11 onwards, not for the LE 1/11 and LE 2/11. Nabertherm designs the furnace for easy maintenance replacement of heating elements and insulation.
Selection guide
If 1 litre of usable volume is not sufficient, the economy series is available in other sizes up to the LE 24/11 with 24 litres, which LT Laborhandel supplies on request. Anyone requiring a higher maximum temperature than 1,100 °C will find muffle furnaces L and LT up to 1,200 °C, 1,300 °C or 1,400 °C at LT Laborhandel, such as the L 3/12 with 3 litres and Tmax 1,200 °C.
Typical applications
The series is intended for use in laboratories and research. With 1 litre of usable volume and a heating time of around 6 minutes, the LE 1/11 is suitable for individual small samples where rapid throughput rather than large volume is important. This value applies to the empty, closed furnace up to 1,000 °C.
