Product information "Nabertherm Muffle Furnace L 3/12/B510, 3 l, Tmax 1,200 °C, Flap Door, L-035K2AL"
The Nabertherm L 3/12 is the 1,200 °C version of the 3-litre size of the L/LT series. Compared to the 1,100 °C variant, a type S thermocouple is fitted in the furnace, and the heating time is slightly longer at around 48 minutes. Where samples regularly need to be heated above 1,100 °C, but no larger chamber is required, this size is suitable.
Heating, insulation and housing
Inside, the chamber measures 160 x 140 x 100 mm, as with the L 3/11, while outside the furnace measures 385 x 330 x 405 mm in a double-walled, rear-ventilated housing made of textured stainless steel sheet. Heating is from two sides via ceramic heating plates with integrated heating wire, protected and easy to replace. Exclusively insulation material without classification according to the CLP Regulation (EG) Nr. 1272/2008 is used, meaning without aluminium silicate wool (RCF fibre). With an empty, closed furnace, heating up to Tmax minus 100 K takes around 48 minutes (230 V 1/N/PE or 400 V 3/N/PE), and the weight is 21 kg.
Type S thermocouple and controller
A type S thermocouple is fitted for the 1,200 °C class, while type N is used at 1,100 °C instead. Control is via the B510 touch controller with 5 programs of 4 segments each, and the heating operates quietly via solid-state relays. NTLog Basic records process data on a USB stick. At operating temperatures above 800 °C, the temperature uniformity in the empty chamber with the air inlet slide closed is +/-5 K according to DIN 17052-1.
Door and safety
The flap door of the L 3/12 also serves as a shelf and has an adjustable air inlet, while the exhaust air is vented through the rear wall. An adjustable temperature limiter with adjustable cut-off temperature can be ordered as an option for additional over-temperature protection.
Auswahlhilfe für die passende Temperaturklasse
If the temperature class up to 1,100 °C is sufficient, the L 3/11 (item no. L-035K1AL) with a type N thermocouple is the alternative. If more chamber volume than 3 litres is required, the size table below shows the next step with the L 5/12.
Typical applications
The L/LT series is intended for use in laboratories and research. For the L 3/12, this applies to small sample quantities that need to be heated up to 1,200 °C and do not otherwise justify a larger furnace.
- Small sample quantities with temperature requirements up to 1,200 °C
- Laboratory workstations with limited bench space
