Laboratory Furnaces from Thermo Fisher Scientific

Box furnaces (also called Ash furnaces) have many appliions in modern research and chemistry laboratories. These furnaces are used to determine the amount of non-coustible and non-volatile (ash) material in a sample. To determine the ash quantity, a sample is placed in the furnace and exposed to high temperatures (typically up to 1,100°C) for a given period of time.
