Volatile Matter Furnace

Volatile Matter Furnaces - VMF/ASTM Series

Overview

The Elite VMF/ASTM Series is a high-precision Volatile Matter Furnace designed for the determination of volatile matter in coal and coke in accordance with ASTM D3175. Engineered for accuracy and consistency, this system delivers reliable volatile matter analysis for industrial and laboratory applications. The VMF/ASTM Series is available in two distinct models:

VMF/ASTM Model

This is the standard version, ideal for routine volatile matter testing. It provides precise temperature control and uniform heating, making it a dependable solution for core volatile matter analysis.

VMF/ASTM + Pre-Heat Model

Specifically engineered for sparked fuels, this advanced model features an integrated pre-heating zone within the same furnace, eliminating the need for external accessories or separate setups.

The pre-heating zone is maintained at 600°C, while the main analysis zone is heated to 950°C, in full compliance with ASTM D3175 requirements.

This dual-stage heating process minimizes sparking and sample disruption, ensuring safe, accurate, and reproducible results-especially for challenging materials like metallurgical coke, anthracite, and other volatile-rich solid fuels.
