Muffle Furnaces are used for high-temperature testing applications such as loss-on-ignition or ashing. Muffle Furnaces are compact countertop heating sources with insulated firebrick walls to maintain high temperatures. The laboratory muffle furnaces offer a range of features including, rugged construction, programmable controllers, and a safety switch that turns off power when the door opens.

Avoid delays and save time at work with standard lab muffle furnaces. Our muffle furnace models are a cut above the rest because of their capacity to supply reliable, consistent high heat.

We made sure to add top-quality parts that sustain high-temperature uniformity for your applications. Our standard units have energy-saving ceramic fiber as the internal material, an iron-chrome wire heater, and tightly sealed doors, which is highly beneficial when the maximum temperature exceeds 1000°C. Not only that, but they also have microprocessor-controlled thermoregulators, which provide outstanding repeatability.

Originally designed to isolate the material from the fuel and products of combustion, modern muffle furnaces are ideal for high-temperature applications such as heat treating, sintering processes, and technical ceramics or soldering. Our range muffle furnaces offer a compact and durable solution for wide range of industrial applications including ashing organic and inorganic samples and gravimetric analysis. Depending upon the model you choose, our range offers up a maximum temperature of 1000o C or 1832o F and capacity range of 1.5 to 30 liters.

Muffle Furnace is used to calculate loss on ignition (LOI) and volatiles on both chemically and clay bonded foundry sands. This calculation allows foundries to monitor and control organic additives in clay bonded sand such as sea coal, cellulose and cereal and binder percentages in chemically bonded sand.

The furnace temperature is adjustable between 100°C – 1,100°C (212oF – 2,012oF) with the operating temperature displayed on a digital display. The furnace is available in a small size with chamber dimensions of 250mm x 135mm x 140mm (9.8” x 5.3” x 5.5”) or a large size with chamber dimensions of 330mm x 200mm x 200mm (13” x 8” x 8”). Both are equipped with a PID temperature controller which has a large, bright digital LED that will display either the set point or process temperature.
