## Applications

- Pyrolysis of environmental and biomass samples under protective gas
- Reduction of oxidic samples prior to XRF
- Thermal analysis methodology and calibration
- Sintering and CVD precursor under controlled atmosphere

## Specifications

| Max temperature | 1100 / 1300 / 1600 / 1800 °C depending on model |
| --- | --- |
| Tube diameter | 40 – 250 mm |
| Heating elements | Kanthal or MoSi₂ |
| Control | P580, programme-controlled, multi-zone option |
| Atmosphere | Shielding gas, reductive or vacuum (optional) |
| Gas flow | Mass flow control with MFC (optional) |
| Configuration | Horizontal or vertical tube, multi-zone |
| Logging | VCD software, temperature, events, gas |

## Description

The R-series is used for thermal processes requiring a controlled atmosphere: pyrolysis of environmental samples, reduction of oxidic samples before XRF, calibration of thermal analysis methods, and sintering of materials under protective gas. Multi-zone configuration provides a uniform temperature zone over longer samples.

We specify tube diameter, number of heating zones, and atmosphere packages based on the method's requirements for heating rate, gas purging, and sample geometry. Gas flow can be regulated with MFC and logged along with the temperature profile.

## Service & support

High- and low-temperature furnaces are workhorse equipment where elements, insulation and controllers wear over time. Our Nabertherm technicians keep the R tube furnace series in calibrated condition for materials analysis and thermal processes.

- Annual temperature calibration with traceable probe (multi-point per AMS 2750/ISO 17025).
- Original parts: heating elements, thermocouples, insulation, controllers.
- Operational assessment and preventive replacement of element bridges before failure.
