Product Details

The Thermo Scientific Thermolyne Benchtop Muffle Furnace is ideal for general laboratory use, including gravimetric analysis, sintering, quantitative analysis and heat treating. It reaches a 1200°C maximum temperature and is available in two capacities for added flexibility. The built-in vent port removes contaminants and moisture to extend the life of the heating element and furnace.

Includes the B1 Digital Controller.

Single setpoint with one ramp and one dwell.

The ramp is used to vary the heat-up rate to your specified setpoint. The furnace will then dwell (hold the temperature) at a set level for a specified time.

Single display shows actual temperature or setpoint.

A mechanical overtemperature protection relay is also included.

Includes ceramic shelf (SH480X1) that doubles furnace load capacity

For added protection, the door safety switch stops power to heating elements when door opens

Thermocouple break protection cuts power to heating elements, preventing a thermocouple failure runaway condition

Two open coil heating elements on chamber sides assure fast heat-up with minimum temperature gradient

Thermal-efficient ceramic insulation surrounds chamber for maximum energy efficiency

Includes a 0.38-inch diameter port for monitoring chamber temperatures with independent measuring device at rear of chamber

Includes Power Cord
