Rapid Thermal Processing System

Rapid visible/IR light heating for lab-scale samples



RTP-1SX is a tube furnace with irradiation heating of samples and low heat capacity body, facilitating rapid heating and cooling of samples. The heating temperature and time can be set, and the atmosphere can be controlled, i.e. inert gas or vacuum. The irradiation is provided by maximum 4 halogen lamps, each 1000 W. The trapped light inside the tube provides high energy concentration for rapid heating of samples.



  • Heating rate up to 900 °C/min
  • Max temperature up to 700 °C
  • Easy replace of heating elements
  • Heating in controlled atmosphere (RTP-1SS) or in vacuum (RTP-1SV)
  • Selection of heating power up to 4000 W
