KSL-1700X-SJ Bench-Top High Temperature Furnace with Evaporating Particle Collection
The KSL-1700X-SJ furnace is engineered for laboratory applications that demand stable high-temperature environments combined with particle filtering capabilities. Its compact bench-top design accommodates materials processing within an 8 inch by 8 inch by 8 inch chamber, making it suitable for research and development tasks involving thermal treatment and evaporation processes.
This furnace utilizes high-grade alumina fiber bricks with reflective coating to optimize energy efficiency and maintain thermal insulation. Heating is provided by super 1800 grade molybdenum disilicide (MoSi2) elements, enabling continuous operation at temperatures up to 1650°C and short-term peaks reaching 1700°C. The system integrates a water chiller atop the unit to separate and collect evaporated particles, enhancing experimental control and safety.

Typical Applications
Ideal for high-temperature material synthesis, sintering, evaporation studies, and thermal processing where particle emission control is required. Suitable for research labs focusing on ceramics, metals, and advanced materials development.
Configuration & Operating Notes
Optional upgrades include advanced temperature controllers such as the Eurotherm 3504 compatible with LabVIEW and a laptop/software package for remote monitoring and control. The furnace requires a suitable plug (not included) and a 32A air breaker. Users should avoid heating or cooling rates exceeding 10°C/min to prolong furnace life. The unit is not vacuum sealed and is not recommended for use with toxic or explosive gases without appropriate safety measures. Minor refractory ceramic surface cracks may develop over time and can be repaired with alumina coating. Proper insertion of refractory blocks before closing the door is necessary for safe operation.
