Description
The Carbolite GSM 11/8 is a specialist ashing furnace designed for controlled combustion and accurate residue analysis in labs performing LOI (Loss on Ignition) and mineral content testing. With a maximum temperature of 1100°C, the GSM series offers higher thermal capability than typical muffle furnaces, making it suitable for advanced materials and precise analytical applications.
Its 8-liter chamber, robust refractory insulation, and excellent airflow control allow it to process organic, inorganic, or mixed material samples with minimal contamination and residue. Ideal for use in QA/QC labs, environmental testing facilities, food processing labs, and academic research, the GSM 11/8 delivers consistency, cleanliness, and exacting performance.
