High-Temperature Strip Heater Chambers:
HTK 16N | HTK 2000N

  • +1

The HTK 16N and HTK 2000N high temperature chambers are well-proven instruments for in-situ X-ray diffraction studies up to 1600 °C and 2300 °C, respectively. The sample is directly heated with a heating filament. The design of HTK 16N and HTK 2000N allows you to work at high temperatures in different atmospheres. The instruments are made of high-quality materials which guarantee a long working life.

Key features

Minimized sample displacement during heating

  • High position stability of the heating filament over the whole temperature range
  • Precise linear stage which compensates for thermal elongation of the heating filament
  • Integrated alignment slits for sample repositioning even at high temperatures

Accurate sample temperature

  • Optimized design for a minimum temperature gradient across the sample
  • Two thermocouples for controlling and measuring the sample temperature

Clever design

  • Superior design and use of high-grade materials
  • Variety of filament materials: platinum, tungsten, tantalum, graphite, and others on request
  • Unique graphite heating filament with detachable inert sample carrier plate
  • Simple handling and quick sample exchange
