KSL1800XS Compact Muffle Furnace with 1.7L Chamber, Kanthal Super-1900 MoSi2 Heating Elements, Up to 1800°C
The KSL1800XS is designed for laboratory applications requiring precise high-temperature heat treatment of materials within a compact footprint. Its 1.7-liter cubic chamber (120 x 120 x 120 mm) accommodates small to medium samples, making it suitable for research tasks such as sintering, annealing, and material synthesis under controlled atmospheres.
This furnace achieves temperatures up to 1800°C for short durations (less than 2 hours) and continuous operation at 1750°C, enabling advanced material processing. The heating elements are Kanthal Super-1900 grade molybdenum disilicide (MoSi2), known for high temperature stability and longevity. The furnace structure includes a double-layer steel casing with an air cooling fan to maintain external surface temperatures below 55°C, enhancing safety during operation.
