Ashing Furnace - AAF - Carbolite

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 Ideal for ashing foods, plastics, coal & other hydrocarbon materials Designed to comply with ISO 1171: 2010 & ASTM D3174-04: 2010 ( AAF 11/ 3 and AAF 11/ 7 only) Wire elements are protected from chemical & mechanical damage by a hard wearing alumina based liner ( AAF 11/ 3 and AAF 11/ 7 only) AAF 11/ 18 and AAF 12/ 18 offer protection of the elements from carbon build-up or corrosive atmosphere, using silicon carbide tiles Air inlet & tall chimney give airflow of 4 to 5 changes per minute ( AAF 11/ 3 and AAF 11/ 7 only) Low chamber height holds airflow close to samples for optimum combustion ( AAF 11/ 3 and AAF 11/ 7 only) Powerful elements with graded winding compensate for heat loss due to high airflow ( AAF 11/ 3 and AAF 11/ 7 only) Preheating of air before it enters the chamber gives excellent uniformity ( AAF 11/ 3 and AAF 11/ 7 only) Large floor area allows for large number of samples AAF 11/ 3 and AAF 11/ 7 come complete with sample tray and loadign handle AAF 11/ 18 and AAF 12/ 18 have two tier rack system doubling sample capacity Models AAF 11/ 3 Max temp ( ° C) 1100 Max continuous operating temp ( ° C) 1000 Volume ( litres) 3 Heat-up time ( mins) 155 Dimensions: Internal H x W x D ( mm) 90 x 150 x 250 Dimensions: External H x W x D ( mm) 585 x 375 x 485 Dimensions: External with door open H x W x D ( mm) 800 x 375 x 485 Dimensions: Height to top chimney ( mm) 780 Max power ( W) 2100 Holding power ( W) 1270 Thermocouple type K Weight ( kg) 22 AAF 11/ 7 Max temp ( ° C) 1100 Max continuous operating temp ( ° C) 1000 Volume ( litres) 7 Heat-up time ( mins) 155 Dimensions: Internal H x W x D ( mm) 90 x 170 x 455 Dimensions: External H x W x D ( mm) 650 x 430 x 740 Dimensions: External with door open H x W x D ( mm) 905 x 430 x 740 Dimensions: Height to top chimney ( mm) 1060 Max power ( W) 4000 Holding power ( W) 2624 Thermocouple type K Weight ( kg) 63 AAF 11/ 18 Max temp ( ° C) 1100 Max continuous operating temp ( ° C) 1000 Volume ( litres) 18 Heat-up time ( mins) 70 Dimensions: Internal H x W x D ( mm) 235 x 196 x 400 Dimensions: External H x W x D ( mm) 705 x 505 x 675 Dimensions: External with door open H x W x D ( mm) 990 x 505 x 675 Dimensions: Height to top chimney ( mm) 990 Max power ( W) 7080 Holding power ( W) 3500 Thermocouple type K Weight ( kg) 70 AAF 12/ 18 Max temp ( ° C) 1200 Max continuous operating temp ( ° C) 1100 Volume ( litres) 18 Heat-up time ( mins) 70 Dimensions: Internal H x W x D ( mm) 235 x 196 x 400 Dimensions: External H x W x D ( mm) 705 x 505 x 675 Dimensions: External with door open H x W x D ( mm) 990 x 505 x 675 Dimensions: Height to top chimney ( mm) 990 Max power ( W) 7080 Holding power ( W) 3500 Thermocouple type R Weight ( kg) 70 Please note: - Heat up rate is measured to 100° C below max, using an empty chamber - Holding power is measured at 500° C - Maximum power and heat up times based on a 240V supply
