KSL-1200X-AC-5S Five-Side Heating Atmosphere-Controlled Muffle Furnace with 64L Capacity and Up to 1200°C Max Temperature
The KSL-1200X-AC-5S furnace is engineered for advanced laboratory material processing requiring precise temperature control and atmosphere management. It is ideal for applications such as material synthesis, thermal treatments, and controlled atmosphere experiments where uniform heating and gas environment control are critical. The furnace chamber is hermetically sealed, allowing operation under inert, reducing, or oxidative gas atmospheres, supporting a wide range of experimental conditions.
This model features five-sided heating with Kanthal Fe-Cr-Al resistance elements embedded in high-quality alumina fiber insulation, ensuring excellent temperature uniformity within a 300 × 300 × 300 mm zone at ±2°C at 800°C. The working chamber volume is 64 liters (400 × 400 × 400 mm), accommodating sample loads up to 35 kg. Continuous operation is supported up to 1100°C, with a maximum temperature of 1200°C allowed for short durations under controlled conditions.
