Innovation and performance data for professional use
Intelligent design, efficient heat and convenient operation
Depending on the model, the muffle furnace is available with a volume of 5, 9 or 15 litres and allows temperatures of up to 1300 °C. Thanks to stone insulation, the heat remains optimally in the furnace, which significantly increases both energy efficiency and safety in the working environment. The innovative lift door offers advantages over standard hinged doors: it opens easily upwards and closes the heating chamber quickly and reliably, which significantly improves ease of use and protects the workplace from heat exposure.

Further technical details: All models are designed for single-phase power connection (110-240 V, 50/60 Hz) and can therefore be flexibly integrated into various laboratory environments. The compact design, combined with a fast heating time of approximately 42 minutes, ensures efficient processes while requiring little space. The models weigh between 42 kg (5 l), 60 kg (9 l) and 70 kg (15 l).
First-class stone insulation and sophisticated heating technology
The stone insulation used by the manufacturer ensures exceptionally low heat radiation to the outside and guarantees consistently precise temperature control inside the chamber. The particularly durable ceramic heating plates are installed in such a way that wear is minimised and easy replacement is guaranteed in the event of servicing.
Comprehensive certifications and compliance with the highest standards
The oven complies with all relevant DIN standards for laboratory ovens and is CE certified. This guarantees not only maximum product safety but also reliability in laboratory processes.
Specific applications in laboratories and industry
-
Dental laboratories / dental technology: Manufacture of dentures, firing processes for dental materials such as ceramics, oxide firing and glaze firing.
-
Metallography & materials testing: Testing the hot and cold strength of metallic samples, annealing and sintering of materials (e.g. steel, aluminium alloys).
-
Fittings and tool manufacturing: Heat treatment (hardening or tempering processes), testing of fittings and tool components for durability and structural changes.
-
Materials research and universities: Development and testing of new materials, thermal decomposition, determination of ash content in plastics and chemical substances.
In addition to these primary areas of application, the muffle furnace is particularly suitable for working with substances such as dental plaster, sintered ceramics, metals and alloys, plastic samples or chemical laboratory preparations.
FAQ - Expert knowledge in a nutshell
How are the heating plates replaced?
The ceramic heating plates are accessible from the front and can be quickly replaced by loosening the fasteners and removing the cover. The process can be carried out by qualified personnel as part of routine maintenance.
What safety precautions must be observed when handling the furnace?
The furnace must be operated on a stable, non-flammable surface. The area around the furnace must always be free of combustible materials. Personal protective equipment - in particular heat-resistant gloves and safety goggles - must be worn during operation.
Is continuous operation at 1300 °C possible?
For optimum service life of the heating elements, Nabertherm recommends a maximum continuous operating temperature of 1200 °C. Short-term processes up to 1300 °C are possible, but are outside the recommended continuous operating conditions.
Can different sample sizes and quantities be processed?
Thanks to different furnace volumes (5 l, 9 l, 15 l), both small individual samples and larger quantities can be processed efficiently. The internal dimensions allow for flexible sample positioning and size.
Conclusion
The advanced muffle furnace with stone insulation and lift door from Nabertherm impresses with its maximum temperature accuracy, robust materials and practical operation. With its excellent insulation, certified safety features and variable interior, it is the first choice for laboratories and industry when it comes to demanding thermal processes. Anyone who values efficiency, durability and ease of use can rely on this laboratory furnace to meet the highest professional standards.
