|  Introduction - for heating of combustible materials for material removal or analysis of ash residue, Carbolite has developed the ashing and burn-off range, which have specific features to enhance ventilation and maintain good temperature uniformity, as well as protect the sample from contamination.
AAF furnaces - these models are heated by wire heating elements protected from chemical and mechanical damage by a high quality alumina based liner. GSM furnaces - some analysis techniques may be affected by alumina or silica dust, the materials normally used to construct the furnace chambers and to avoid this the GSM furnace chamber is constructed from a fused quartz material. CWF/BWF furnaces - The CWF is ideal for burn-off or ashing of natural materials such as natural fibres and cereal food stuffs. The BWF is ideal for cleaning processes such as removing wax from ceramic moulds. Accessories - a range of accessories to complement the ashing and burn-off range of furnaces. |
