Chamber furnace AAF 11 series

preheatingcalcinationcombustion

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 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 & 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 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
