Ashing furnaces are designed for one of the most demanding thermal analysis applications in the laboratory: removing combustible material from a sample through high-temperature oxidation so the remaining inorganic residue can be analyzed.
These furnaces are commonly used in:
Because ashing procedures require extreme temperatures, excellent thermal consistency, and repeatable heating profiles, the brand you choose can significantly impact:
Some furnace manufacturers focus on industrial-grade thermal processing, while others prioritize precision laboratory control and analytical consistency.

Most ashing applications require temperatures between:
Selecting a furnace with headroom above your target operating temperature helps improve long-term stability and heating performance.
Uniform chamber temperatures are critical for achieving consistent residue analysis results across multiple samples.
Advanced controllers can improve repeatability by allowing users to create:
Consider:
Ashing applications often produce smoke or combustion byproducts, making proper ventilation and airflow management important.
The best ashing furnace depends largely on whether your laboratory prioritizes precision analytical performance, industrial durability, or general laboratory versatility.
For routine laboratory workflows, a versatile and easy-to-use furnace may be ideal. For advanced analytical testing or highly regulated environments, premium thermal precision and programmable process control become much more important.

Ashing furnaces are used to burn off organic material from a sample so the remaining inorganic ash content can be analyzed.
Most ashing procedures occur between 500°C and 1000°C depending on the sample type and testing standard.
Many ashing furnaces are muffle furnaces. “Ashing furnace” refers to the application, while “muffle furnace” refers to the furnace design.
Consistent temperatures help ensure complete combustion and repeatable analytical results across all samples.
Nabertherm is often preferred for analytical and research environments because of its precise temperature control and advanced programming capabilities.
