Perform ultra-high temperature applications with the Thermo Scientific™ Thermolyne™ Industrial Benchtop Muffle Furnace, which reaches a maximum temperature of 1200°C. Unit includes multiple safety features and choice of two temperature-control options. Heavy-duty firebrick insulation surrounds the opening for added durability.

  • Adjustable Alarm or Overtemperature Protection (OTP) setting can be used to protect the furnace or loaded chamber from excessive heat
  • Thermocouple break protection cuts power to the heating elements, preventing a thermocouple failure runaway condition
  • Counter-weighted door swings upward, directing heat away from operator
  • Heavy-duty firebrick insulation surrounds chamber opening for added durability
  • Four individual embedded elements in special refractory cement permit excellent heat distribution in the chamber
  • Door safety switch protects operator by removing power to the heating elements upon opening the door
  • Rear-mounted 0.38in. (0.95cm) diameter port for monitoring chamber temperatures with independent measuring devices
  • LED display simultaneously shows both setpoint and actual furnace temperatures in either °C or °F (programmable models only)

Single-setpoint Controller (B1)

  • Single ramp to setpoint and a dwell
  • Single display shows actual temperature or setpoint

8-step Programmable Controller (C1)

  • Ramps to vary heat-up rate and dwell cycles to hold temperature at set levels from 0.1 to 999.9 minutes
  • “Holdback” feature “holds” program until furnace temperature heats up or cools down to preprogrammed parameters—program will never outrun furnace performance


Oven, Platinel™ II thermocouple and a ceramic hearth plate to protect the bottom heating element.


120V models require fixed wiring and are not supplied with a power cord.
