KSL1100XSH Compact Hybrid Furnace with 4x4x4″ Chamber, 1000°C Max, Muffle and Tube 2-in-1 Design
The KSL1100XSH is designed for laboratories requiring precise thermal processing of small samples up to 1000°C within a compact footprint. Its 4″ x 4″ x 4″ heating chamber accommodates sample preparation tasks under vacuum or controlled atmospheres, making it suitable for sintering and material treatments inside glove boxes. This furnace integrates both muffle and tube furnace functionalities, enabling versatile workflows without the need for multiple devices.
This hybrid furnace operates with high-purity fibrous alumina insulation to minimize energy consumption, using only 500 to 700 W during operation. The system includes a quartz tube insertable into the chamber, available in 1″ or 2″ outer diameter sizes, each equipped with a mechanical pressure gauge for accurate vacuum or gas pressure monitoring. The furnace supports a maximum temperature of 1000°C for short durations and 900°C for continuous use, with a heating rate of up to 30°C per minute. The PID controller with auto-tune and programmable segments ensures precise temperature regulation and safety features such as overheat and thermocouple break protection.
