Nabertherm muffle furnace with lift door
The Nabertherm muffle furnace with lift door is the ideal solution for professional laboratory applications where maximum precision and reliability are required. Developed and manufactured in Germany, this industrial furnace impresses with its robust construction, impressive temperature stability and flexible application options. Compared to conventional laboratory furnaces, this model sets new standards in terms of ease of use and technical features - across a wide range of volumes and equipment options.
Precise heating technology for demanding laboratory processes
For analytical laboratories, material testing and applications in ceramics, metallurgy and chemistry, the muffle furnace with lift door offers an optimal combination of performance, durability and ease of use. The model series covers a wide range - from compact 3 litres for individual samples to 40 litres for larger batches or high sample throughputs. With professional ceramic heating elements, the system enables homogeneous heat distribution while protecting against splashes and escaping gases, guaranteeing a long service life and easy maintenance.
Important technical data at a glance
- Maximum temperature: 1,100 °C or 1,200 °C (depending on model)
- Oven volume: from 3 to 40 litres
- Power: 1.2 kW - 6 kW
- Ceramic heating plates with integrated heating wire (splash and exhaust gas protected)
- High-quality, double-walled stainless steel structural sheet (heat-insulating and robust)
- NT-Log Basic data acquisition, USB interface, VCD software integration possible
- Connection options: 1- or 3-phase for international compatibility
In addition, the furnaces feature fibre insulation to reduce energy loss. Integrated air intake openings in the door and exhaust air openings at the rear of the furnace ensure optimum air flow and exhaust gas management - essential for reproducible results in thermal analysis. The proven lift door design allows for easy and safe loading and unloading, even at high temperatures. For specific requirements, there are model variants with 1-phase or 3-phase power connection and customisable performance data.
Model overview
The models range from the LT 3/11 (3 l, 1100 °C) to medium sizes for e.g. combustion chambers with 9/12 litres to large volumes such as the LT 40/12 (40 l, 1200 °C). The respective internal and external dimensions, power consumption and heating times are tailored to the respective process requirements.
External dimensions vary, for example, from 385 x 330 x 405 mm (LT 3/11) to 530 x 705 x 580 mm (LT 40/12) - and are even larger with the additional lift door open. Depending on the model, the heating times range between 40 and 85 minutes to reach the target temperature.
Certifications and standards
The muffle furnace is CE-certified for safe operation in the laboratory and complies with all relevant European and international standards in the fields of industry, analysis and materials testing. The double-walled design also guarantees protection against unwanted heat loss and increases stability, even when handling chemicals or metals.
Specific application examples for laboratories and industry
-
Material analysis and heat treatment: Temperature-controlled annealing, baking and tempering of metals (steel, aluminium, copper), analysis of metallurgical samples, and thermal pre-treatment for further testing processes.
-
Ceramic and glass processing: Firing of laboratory ceramics, sintering of dental materials, fusing processes with glass and performance of expansion tests.
-
Ash determination and chemical analysis: Performing ash tests (e.g. in environmental analysis or food analysis for organic/inorganic residue determination) and substance analyses (e.g. total and residual ash, heavy metal content).
-
Combustion tests and quality tests: Standardised thermal stress tests on plastics, chemicals, building materials or pharmaceutical components under controlled atmosphere conditions.
In particular, materials such as iron, lead, silicates, ceramic masses, glass and mineral samples are typically treated or tested in a muffle furnace.
FAQ
Which models are suitable for a high sample throughput rate?
Models with a larger furnace volume, such as LT 24/11, LT 24/12, LT 40/11 and LT 40/12, are ideal for larger batches and continuous use.
How is uniform temperature distribution ensured?
The patented ceramic heating plates, combined with fibre insulation, ensure a homogeneous atmosphere in the combustion chamber - regardless of the sample position.
What safety features does the furnace series offer?
All models feature a double-walled construction to protect against heat loss and contact burns, an automatically closing air inlet and exhaust gas-optimised exhaust air management. The devices are CE certified.
Are all models adaptable to international laboratory power grids?
All furnace models can be supplied for connection values from 110 V to 240 V (single-phase) or 200 V to 480 V (three-phase), suitable for 50 or 60 Hz.
What should be considered during continuous operation?
For longer holding times, the maximum continuous operating temperature (1,000 °C for 1,100 °C models, 1,100 °C for 1,200 °C models) should be observed.
Can older control units be retrofitted?
Yes, current models offer interfaces for NT-Log-Basic and VCD software; USB data output is available as standard or as an option.
For which areas are the models particularly suitable?
The furnace series are designed for use across a wide range of industries for research, material development, quality assurance and training laboratories.
