One of the most common applications for laboratory furnaces is to heat combustible samples in order to analyse the ash residue.

As there is no single solution for all requirements, Carbolite Gero offers a range of ashing furnaces with characteristics tailored to ashing and burn-off applications.

AAF Furnaces
This range is ideal for ashing foods, plastics, coal & other hydrocarbon materials and has optional over-temperature protection for unattended operation. A version of this furnace with a 17 litre capacity is available with an integrated balance for thermogravimetric analysis (TGA). It can be used for loss on ignition applications where weight change of the sample must be monitored during the heating process.

GSM Furnaces
Some analysis techniques may be affected by alumina or silica dust (Al2O3 and SiO2) - the materials normally used to construct furnace chambers. To avoid this the GSM furnace chamber is constructed from a fused quartz material.

ABF Furnaces
The ABF Afterburner Ashing Furnace is particularly suitable for ashing larger samples or materials such as biomass, which are likely to generate substantial amounts of smoke. The exhaust from the main chamber is processed through a high temperature afterburner designed to further process fumes and smoke.
