KSL1200XL Large 1200°C Muffle Furnace with 64L Chamber, Digital PID Controller, and Venting Port
The KSL1200XL is designed for laboratory applications requiring a spacious heating chamber with precise temperature control up to 1200°C. Its large internal volume of 64 liters (16″ x 16″ x 16″) accommodates sizable samples or multiple items simultaneously, making it suitable for heat treatment, material testing, and sintering tasks where uniform high temperatures are essential.
This furnace achieves rapid heating through heating elements installed on three interior sides, ensuring enhanced temperature uniformity throughout the chamber. The thermal-efficient ceramic insulation, composed of high-purity alumina fiber, minimizes heat loss and improves energy efficiency. A built-in vent port facilitates the removal of contaminants and moisture, which helps prolong the lifespan of heating elements and the furnace itself. Safety features include a heavy-duty double-layer structure with a cooling fan to keep exterior surfaces safe to touch and an interlock system that cuts power immediately when the door is opened.

Configuration & Operating Notes
The furnace includes a digital PID temperature controller capable of programming up to 30 segments with ramp, dwell, and cooling steps. Optional upgrades include advanced Eurotherm controllers with LabVIEW compatibility and software kits for temperature profile management and data logging. A quartz observation window is available upon request for monitoring samples during operation.
For extended furnace life, it is recommended to limit heating and cooling rates to 10°C per minute. The furnace is not vacuum sealed and is not suitable for toxic or explosive gases without appropriate safety measures. Minor surface cracks in refractory ceramics may develop over time and can be repaired with alumina coating products.
