Thermo Scientific Thermolyne 5.8L B1 Benchtop Muffle Furnace

Click for Accessories

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.

Features of the F48020 Furnace

Includes the B1 Digital Controller (see below for alternate controllers). 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

Alternate Controller Options

The F48020 furnace includes the B1 digital controller and is also available with alternate digital controllers allowing for various levels of control and programs.

A1 - Single setpoint to hold a specified temperature. Single display shows the actual temperature or setpoint.

C1 - Programmable with one (1) stored program of eight (8) segments. Each segment includes one ramp and one dwell, so you can program 8 ramp/dwell cycles. 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. An LED display simultaneously shows both setpoint and actual furnace temperatures. A mechanical overtemperature protection relay is also included.

D1 - Programmable with four (4) stored program of sixteen (16) segments. Each segment includes one ramp and one dwell, so you can create four programs with 16 ramp/dwell cycles. 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. An LED display simultaneously shows both setpoint and actual furnace temperatures. A mechanical overtemperature protection relay and RS-232 communications interface are also included.
