KSL1700XA2 1700°C Benchtop Muffle Furnace with 8×8×8″ Heating Chamber, Fiber Alumina Insulation, and MoSi2 Elements
KSL1700XA2 is designed for laboratory applications requiring high-temperature heat treatment up to 1700°C, such as material sintering, annealing, and thermal testing. Its compact benchtop design accommodates samples within an 8×8×8 inch (8.4 L) heating chamber, providing a controlled environment for precise thermal processing. This furnace is suitable for workflows demanding uniform temperature distribution and reliable performance at elevated temperatures.
The furnace operates using six super 1800-grade molybdenum disilicide (MoSi2) heating elements embedded within a chamber insulated by 1800-grade fiber alumina with reflective coating. This insulation maximizes energy efficiency while maintaining a safe exterior temperature below 60°C, thanks to a double-layer steel casing with an integrated air cooling fan. Temperature control is managed by a FA-YD518P-AG PID controller offering ±1°C accuracy, programmable segments, and safety alarms. The unit supports a heating rate up to 20°C/min, with a recommended maximum of 10°C/min for optimal thermal cycling.

Typical Applications
- High-temperature sintering and annealing of ceramics, metals, and composites
- Thermal testing and material research requiring precise temperature control
- Heat treatment processes in research and development laboratories
Configuration & Operating Notes
- Optional Eurotherm 3004 temperature controller and PC communication kit (MTS01) available for advanced programming and data logging
- Recommended heating/cooling rate is ≤10°C/min to prevent damage and ensure uniformity
- Small surface cracks on refractory ceramics may develop over extended use; this is normal wear
- Refractory block must be properly inserted before closing the furnace door for safe operation
