Overview

About the Muffle Furnace

The Muffle Furnace is used to determine the percentage of ash in polymers. In the test, a weighed polymer sample is heated to a high temperature so that the organic material burns off completely, leaving behind only the inorganic ash or filler. By weighing this residue, the ash content of the material can be calculated — an important check of filler and reinforcement levels in plastics and compounds.

With a temperature range from ambient to 1150°C, a 4″ × 4″ × 9″ working chamber and rugged M.S construction, the furnace provides stable, uniform heating for ash content, loss-on-ignition and other high-temperature laboratory tests. Furnaces with other chamber sizes can also be supplied to suit different sample volumes.

FAQ

Muffle Furnace — FAQs

What is a Muffle Furnace used for?
It determines the percentage of ash in polymers: the sample is heated to a high temperature so the organic material burns off, leaving the inorganic ash or filler, which is weighed to calculate ash content.
What is the temperature range?
Ambient to 1150°C, sufficient for ash content, loss-on-ignition and related high-temperature tests on plastics and compounds.
What is the chamber size and construction?
The standard working chamber is 4″ × 4″ × 9″ with mild-steel construction and a powder-coated finish; other sizes can be offered.
Do you export the Muffle Furnace?
Yes. We export to more than 50 countries and have equipped over 10,000 laboratories in India and abroad.
