Thermo Scientific Thermolyne Industrial Benchtop Muffle Furnaces.

Rugged design with multiple safety features and choice of two temperature control options.

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


  • Reaches 1200°C maximum temperature
  • Heavy-duty firebrick insulation
  • Adjustable alarm or Over-temperature Protection (OTP) setting
  • Thermocouple break protection cuts power to the heating elements
  • Counter-weighted door swings upward
  • Four individual embedded elements in special refractory cement
  • Door safety switch protects operator
  • Rear-mounted 0.38in. (0.95cm) diameter port
  • LED display


  • Surrounds the opening for added durability
  • Can be used to protect the furnace or loaded chamber from excessive heat
  • Preventing a thermocouple failure runaway condition
  • Directing heat away from the operator
  • Permit excellent heat distribution in the chamber
  • By removing power to the heating elements upon opening the door
  • For monitoring chamber temperatures with independent measuring devices
  • Simultaneously shows both setpoint and actual furnace temperatures in either °C or °F (programmable models only)
