Nabertherm Ashing Furnace with Hinged Door
The Nabertherm ashing furnace with hinged door is the precise solution for demanding laboratories and industrial companies that require reliable and standardised ashing processes. The furnace enables efficient analysis of samples, for example for ash determination in foodstuffs, environmental analysis or materials research. Innovative airflow, maximum temperature stability and extensive safety features make this device the preferred choice over conventional muffle furnaces.
Performance characteristics and technical details
The Nabertherm ashing furnace combines effective sample ashing with maximum user safety and durability. The sophisticated air supply and exhaust system ensures a high air exchange rate of over 6 times per minute, which guarantees particularly complete and rapid combustion of the samples. At the same time, flexible usable space sizes and the high maximum temperature enable a wide range of applications, from quality control in the food industry to analytical determination in environmental technology.

Special features of the Nabertherm incineration furnace
A key unique selling point of this device is its excellent temperature stability, confirmed by its compliance with DIN 17052-1. The sophisticated safety concept reliably protects users: the design minimises the risk of burns, a temperature selector limiter ensures that critical temperature ranges are not exceeded, and the housing remains comparatively cool even during continuous operation. The insulation materials used are low-emission and comply with the CLP Regulation (EC No. 1272/2008).
Standards and certifications
The furnace meets high requirements in terms of occupational safety and environmental compatibility:
- Use of insulation materials that are not classified as hazardous (according to EC Regulation No. 1272/2008, CLP)
- Suitability for standardised ashing processes according to ASTM, ISO, EN and various DIN standards
- Temperature uniformity according to DIN 17052-1 in the relevant working range
Application examples from laboratories and industry
Thanks to its combination of flexible chamber size, high temperature control and product-specific protection mechanisms, the furnace is used across a wide range of industries. Typical applications include:
-
Food analysis: Dry ashing to determine the ash content in dairy products, flours, plant-based or animal-based foods, for example.
-
Environmental analysis: Analysis of heavy metals or pollutants in soil and water samples by pre-combustion of the organic matrix.
-
Materials research: Testing of plastics, organic and inorganic materials, and residues in industrial components.
-
Pharmaceutical quality control: Incineration of tablets and granules to determine inorganic components.
Commonly used substances and sample materials:
- Food samples (e.g. sugar, cereals, milk)
- Soil and sewage sludge samples
- Plastics, polymers, resins
- Plant or animal reference materials
FAQ - Frequently asked questions about the use of the Nabertherm ashing furnace
How is uniform temperature distribution ensured?
Heating is provided from two sides with coordinated control. Precise temperature control and a special chamber design result in a temperature precision of ±10 °C in the working chamber (according to DIN 17052-1).
What safety mechanisms are integrated?
The furnace has a double-walled stainless steel housing with low surface temperatures, a door mechanism facing away from the working area, a temperature limiter and low-emission insulation materials for safe operation.
Can multiple samples be treated in parallel?
Yes, thanks to the large usable volume and perforated plates, multiple sample vessels can be placed on the furnace at the same time and ashed evenly.
Is operation safe even in continuous use?
The robust materials, low-noise semiconductor technology and temperature selector limiter ensure safe operation even over longer periods of time, provided the recommended maximum temperatures are observed.
Can different mains voltages be used?
The furnace can be operated at connection values from 110 V to 240 V, each single-phase at 50 or 60 Hz - this ensures global usability.
Conclusion
With its robust construction, powerful ventilation system and outstanding temperature control, the Nabertherm ashing furnace with hinged door meets all requirements for precise and safe ashing processes in laboratories and production. Its flexibility in terms of volumes and connection values, complemented by a wide range of safety features and compliance with important standards, makes it the ideal investment for professional, standard-compliant combustion and analysis steps in a wide variety of industries.
