The 2-Zone Split Tube Furnace 1200°C – TT-TF2Z-150-1200 is engineered for sintering and high-temperature heat treatment of metals, ceramics, nanomaterials, semiconductors, powder metallurgy, and other advanced materials. Widely utilized in universities, research institutes, industrial facilities, and sectors such as petrochemicals and aerospace, this dual-zone furnace offers precise thermal control and uniform heating. It features a high-purity quartz tube with an outer diameter of Φ150 mm and two independently controlled heating zones, each 300 mm in length, allowing optimized temperature distribution.
The furnace operates continuously at temperatures up to 1200°C, with a maximum working temperature of 1100°C. Powered by 220 V/5.2 kW (110 V available), it incorporates high-quality HRE alloy resistance wire elements, an N-type thermocouple, and delivers temperature precision of ±1°C. This ensures reliable, reproducible results for advanced research and industrial applications, making it an ideal solution for laboratories and manufacturing environments requiring consistent high-temperature processing.
