Thermolyne F48025-60 Muffle Furnace, Single Setpoint, 5.8L

Thermolyne F48025-60 Muffle Furnace, Single Setpoint, 5.8L

The Thermolyne F48025-60 Muffle Furnace is a high-performance, single setpoint benchtop furnace engineered for precision and durability in laboratory and industrial settings. It is an indispensable tool for a wide range of applications, including ashing, ignition tests, gravimetric analyses, and volatile matter determinations. In the construction materials industry, it is specifically used for testing soils, aggregates, and cement.

Performance and Construction Built with rugged components and superior materials, this furnace is designed for a long service life. It reaches a maximum temperature of 1200°C (2192°F) and features a 5.8L (0.2ft³) chamber. The thermal-efficient ceramic insulation and open-coil heating elements on the chamber sides ensure rapid heat-up times and excellent temperature uniformity within the core heating zone. A built-in vent port at the rear of the chamber allows for the removal of moisture and contaminants, which not only purges the chamber but also significantly extends the life of the heating elements.

Control and Safety The furnace is equipped with a sophisticated single setpoint controller. This allows the operator to set a target temperature, and the furnace will ramp directly to that point and dwell there. The 0.3in (7.6mm) LED digital display clearly shows the actual temperature or the setpoint and can be toggled between °C and °F.

Safety is a paramount design consideration. The unit features built-in thermocouple break protection, which automatically cuts power to the heating elements in the event of a sensor failure, preventing uncontrolled heating. An oven door safety switch performs a similar function, cutting power when the door is opened to protect the operator. For enhanced quality control, a rear port allows for the monitoring of chamber temperatures with an independent measuring device.

Included with the Furnace:
