1700°C Rocking Tube Furnace with 60mm OD Alumina Processing Tube - GSL-1700X-RC

0.0/5 rating (0 votes)


GSL-1700X-RC is a high-temperature rocking tube furnace up to 1700ºC. The processing tube is made of a 2" ID alumina tube. The rocking mechanism can drive the furnace swing +/- 45º  from right to left at variable speed.   It is designed for processing materials under controlled atmosphere gas at high temperatures to achieve more uniform composition.


  • Double-layer steel casing with air cooling to keep the case temperature < 60oC.
  • High purity fibrous alumina chamber with max energy saving.
  • Alumina tube, vacuum flange, gauge & valves are included.
  • 1800 grade MoSi2 Heating Elements allows 1700C operation
  • Precision temperature control with +/- 1oC accuracy


  • AC 208 - 240V 50/60Hz, single-phase
  • 3.0 KW (20A breaker required)
