OTF-1200X-7Z-8 Seven-Zone Split Tube Furnace with 82.6″ Heating Length and 8″ ID Quartz Tube, Up to 1200°C
The OTF-1200X-7Z-8 furnace is engineered for laboratory processes demanding precise thermal management over a long heating zone. Its seven independently controlled heating zones span a total length of 2100 mm (82.6 inches), enabling the creation of a highly uniform temperature region of 1350 mm with a stability of ±2°C. This capability supports complex thermal profiles and gradient experiments in materials research and processing.
The furnace incorporates an 8-inch inner diameter quartz tube with stainless steel vacuum flanges, allowing for controlled atmosphere or vacuum conditions down to 10-5 torr with optional turbopumping. The system includes two needle valves for gas inlet and outlet, a pressure gauge, and a water-cooled flange jacket to maintain operational integrity under high temperatures up to 1200°C.
주요 기능
- Seven programmable digital temperature controllers with K-type thermocouples, providing ±1°C accuracy and PID control with 30 programmable segments.
- Double-layer steel casing with dual cooling fans to maintain surface temperatures below 70°C for safety and energy efficiency.
- High-purity fibrous alumina insulation and buffer thermal blocks included; quartz thermal blocks available optionally for enhanced cleanliness.
- Electric cylinders automate the opening and closing of the top split cover for ease of access and sample handling.
- Integrated vacuum sealing system with stainless steel 304 flanges, double high-temperature silicone O-rings, and water cooling jacket.
- RS485 communication port with optional software for laptop control and monitoring of temperature profiles.
- Optional Eurotherm 3000 controllers available for enhanced temperature accuracy of ±0.1°C and recipe management.
