LV (LVT) Series: Highly reliable ashing furnaces

Ashing furnace LV ../11 is designed especially for ashing processes to 1050°C in the laboratory. Applications include determining loss on ignition, ashing plastics for subsequent substance analysis. A special fresh-air and exhaust air system ensures that the air is replaced 6 times per minute so that there is always sufficient oxygen for the ashing process. Incoming air passes the furnace heating and is pre-heated to ensure good temperature uniformity.


  • Tmax 1100 °C
  • Heating from two sides
  •  Ceramic heating plates with integral heating element which is safeguarded, and easy to replace
  • Air exchange of more than 6 times per minute
  • Good temperature uniformity due to preheating of incoming air, temperature uniformity according to DIN 17052-1 to +/− 10 °C in the defined empty work area (from 550 °C)
  • Dual shell housing made of textured stainless steel sheets with additional fan cooling for low surface temperature
  • Exclusive use of insulation materials without categorization according to EC Regulation No. 1272/2008 (CLP)
  • Suitable for many standardized ashing processes according to ISO, ASTM, EN, and DIN
  • Optional flap door (LV) which can be used as work platform or lift door (LVT) with hot surface facing away from the operator
  • Controller B510 (5 programs with each 4 segments)
  • Solid state relays provide for lownoise operation
  • NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive
