Muffle Furnace

A compact muffle furnace to determine the percentage of ash in polymers — a mild-steel chamber operating from ambient to 1150 °C, with other sizes offered on request.

  • Determines percentage of ash in polymers
  • Working chamber 4 in × 4 in × 9 in (other sizes on request)
  • Temperature range ambient to 1150 °C
  • Powder-coated MS body; 230 V single-phase
Made in IndiaISO 9001:2015CE CertifiedExported to 60+ countries
Overview

High heat for ash and residue determination

Burning off the polymer at high temperature leaves the inorganic ash and fillers behind, and weighing that residue gives the ash content — a key composition check for polymers and part of the carbon black content method.

International Equipments builds a compact muffle furnace with a 4 × 4 × 9 in mild-steel chamber reaching 1150 °C, for percentage of ash in polymers. Other sizes are available on request. Manufactured in Mumbai, CE marked and calibration-certified.

How the test works

Step by step

  1. Weigh the crucibleWeigh a clean, empty crucible.
  2. Add the sampleWeigh a polymer sample into the crucible.
  3. HeatPlace in the furnace and heat to the specified temperature until the polymer burns off.
  4. Cool & weighCool the crucible in a desiccator and weigh the residue; calculate percentage ash.

FAQ

Frequently asked questions

What is the muffle furnace used for?
It determines the percentage of ash in polymers — burning off the polymer and weighing the inorganic residue at temperatures up to 1150 °C.
What is the standard chamber size?
4 in × 4 in × 9 in; other sizes are available on request.
How does it relate to carbon black content?
High-temperature ashing is part of determining filler and, with pyrolysis, carbon black content — the muffle furnace complements the dedicated Carbon Black Content Apparatus.
Do you export it with documentation?
Yes — CE marked, voltage-configured and shipped with a calibration certificate to 60+ countries.
