Originally, lab muffle furnaces were developed to isolate the material under heat treatment from combustion fuels, preventing contamination from ash, gas fumes, or soot. With the advent of electric heating elements, these by-products were removed, and today the terms “muffle” and “chamber” furnace are used interchangeably.
Facerom offers a comprehensive range of high-quality muffle furnaces, built to precise standards for long-lasting durability. Available as bench-mounted or larger floor-standing units, these muffle chamber furnaces can achieve temperatures up to 1800°C (3272°F). Developed over the past decade by Facerom’s expert engineering team, they reflect advanced design and reliability.
With a longstanding history of supplying furnaces worldwide, the Facerom name has become synonymous with ‘Leading Heat Technology.’ Many of our muffle furnaces produced nearly a decade ago remain in operation today, maintained through regular preventative service.
No matter your budget, we offer high-quality solutions that surpass expectations, featuring rapid ramp-up times, excellent temperature uniformity, and intuitive touch-screen controls. Optional features include built-in balances for thermogravimetric analysis (TGA) and loss on ignition (LOI) applications, as well as afterburners to eliminate excessive smoke and harmful fumes during heat treatment.
Our broad range of standard products ensures a suitable solution for most needs, while our custom design service enables us to accommodate nearly any specific customer requirement.
Muffle furnace solutions - Frequently Asked Questions
What is a lab muffle furnace?
A laboratory muffle furnace is a heating device specifically designed to ensure precise temperature regulation and consistent heat distribution, which are vital for laboratory tasks. Frequently used in labs, it supports a variety of functions such as ashing and heat treatment of materials. These furnaces are also known as chamber or box furnaces.
What is a lab muffle furnace used for?
Muffle furnaces are suitable for a variety of applications such as ashing, material heat treatment, annealing, calcination, loss on ignition analysis, thermogravimetric analysis, quenching, and sintering.
What is the temperature range of a lab muffle furnace?
Muffle furnaces come with various maximum temperature ratings, determined by the type of heating elements used. The most common models utilize metallic wire elements, reaching temperatures between 1000°C and 1200°C. Furnaces equipped with silicon carbide elements can operate up to 1600°C, while those with molybdenum disilicide elements can achieve temperatures as high as 1800°C.
How long does a muffle furnace require to reach maximum temperature?
The time it takes for a muffle furnace to reach its maximum temperature depends on several factors, including the furnace's size, the available maximum power, and the construction materials. A small laboratory-scale furnace with low thermal mass insulation can achieve maximum temperature in approximately 20 minutes, while larger furnaces using dense refractory materials may require several hours to reach the same temperature.
