AAF Series - 3 & 7 litres


The AAF ashing furnace range is designed specifically to provide optimum ashing conditions to ensure complete combustion of the sample. The AAF 11/3 & AAF 11/7 ashing furnaces provide a continuous flow of preheated air through the chamber, and are designed to comply with ISO 1171:2010, ASTM D3174-04: 2010 and ASTM D4422.

Standard features

  •  1100°C maximum operating temperatures
  •  Carbolite Gero 301 controller, with single ramp to set-point & process timer
  •  Large floor area allows for large numbers of samples
  •  Ideal for ashing foods, plastics, coal & other hydrocarbon materials
  •  Designed to comply with ISO 1171:2010, ASTM D3174-04:2010 and ASTM D4422
  •  Wire elements are protected from chemical & mechanical damage by a hard wearing alumina based liner
  •  4 sided heating (2 sides, roof & hear th)
  •  Air inlet & tall chimney give air flow of 4 to 5 changes per minute
  •  Low chamber height holds air flow close to samples for optimum combustion
  •  Powerful elements with graded winding compensate for heat loss due to high air flow
  •  Preheating of air before it enters the chamber gives excellent unifor mity
  •  Sample tray and loading handle
