  • 208/240 volts, 50/60 hertz — Product is obsolete — Thermo Scientific has depleted all of its stock inventory


  • Achieve rapid heat up, recovery and cool down with a tube furnace that delivers outstanding energy release, reducing thermal process cycle time.
  • Thermo Scientific Lindberg/Blue M 1700°C Tube Furnaces feature heating elements with unique right-angle bend and sidewall mounting to deliver exceptional energy release, reduced thermal process cycle time, and cost savings through quicker throughput.
  • Thermo Scientific Moldatherm graduated-density insulation provides safety, performance and outstanding radial and linear temperature uniformity with resistance to thermal shock.
  • Not available in Europe.


  • Heating elements tolerate rapid cycling over extended periods; elements are easily replaceable without the need to match resistance values.
  • Type “B” thermocouples assure accurate temperature measurement and long thermocouple life; 10' compensated lead wire with polarized plug included.
  • Moldatherm graduated density insulation adds to safety and performance by forming enhanced insulation protection between the high-temperature chamber and exterior cabinet surface.
  • Double-shell construction and convection cooling design reduces exterior surface temperature.
  • Removable louvered panels provide easier access to heating elements and thermocouple.
  • Temperature range: 500°C to 1700°C.


  • Independent digital temperature control module, available separately.
