KSL-1800X-A1-W Bench-Top Muffle Furnace with 1800°C Max Temperature, 3.6L Chamber, Sapphire Observation Window
KSL-1800X-A1-W is designed for laboratory applications requiring ultra-high temperature heating up to 1800°C. Its compact 6 x 6 x 6 inch chamber volume of 3.6 liters accommodates small-scale sample processing, while the integrated 25 mm diameter sapphire observation window enables real-time visual monitoring or high-speed camera recording of thermal processes. This feature supports precise control and documentation of heating experiments involving melting or material transformations.
The furnace utilizes a zirconia ceramic liner capable of withstanding temperatures up to 2000°C, ensuring durability and thermal insulation. Heating is provided by four Kanthal Super-1900 grade molybdenum disilicide (MoSi2) elements rated for continuous operation at 1750°C and short-term peaks to 1800°C. The double-shell steel casing includes a cooling fan to maintain a safe external surface temperature. A 20 mm diameter feeding port on top allows addition of doping materials or installation of an optional stirring mechanism during melting processes.
