Ashing Furnace - AAF



The AAF ashing furnace is designed specifically to provide optimum ashing conditions to ensure complete combustion of the sample.

For those laboratories where ashing is interspersed with other heat treatment work the AAF 12/18 provides all of the advantages of an ashing furnace, but with a higher maximum operating temperature of 1200 °C.

Standard features

  • 1100 °C & 1200 °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
  • AAF 11/3 & AAF 11/7:
  • 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 & hearth)
  • Air inlet & tall chimney give airflow of 4 to 5 changes per minute
  • Low chamber height holds airflow close to samples for optimum combustion
  • Powerful elements with graded winding compensate for heat loss due to high airflow
  • Preheating of air before it enters the chamber gives excellent uniformity
  • Sample tray and loading handle
  • AAF 11/18 & AAF 12/18:
  • Protection of the elements from carbon build-up or corrosive atmosphere, using silicon carbide tiles
  • 2 sided heating
  • Two tier rack system doubling sample capacity

Options (specify these at time of order)

  • 2 phase electrical supply for AAF 11/7
  • Over-temperature protection (recommended to protect valuable contents & for unattended operation)
  • A range of sophisticated digital controllers, multi-segment programmers and data loggers is available. These can be fitted with RS232, RS485 or Ethernet communications
