OTF-1200X-IV Four-Zone Split Tube Furnace with Up to 1200°C Max Temperature and Optional Large Diameter Quartz Tubes
The OTF-1200X-IV is engineered for laboratory processes requiring precise thermal treatment of samples such as annealing, diffusion, and sintering in various gas atmospheres. Its design accommodates large or long samples by providing a 47-inch (1200 mm) total heating zone divided into four independently controlled zones, each 11.8 inches (300 mm) long. This configuration enables a uniform temperature zone up to 36 inches long within ±5°C, critical for consistent sample processing.
The furnace supports quartz tubes with inner diameters of 8″, 10″, or 14.5″, allowing flexibility for different sample sizes and experimental setups. Each quartz tube is paired with stainless steel 304 vacuum flanges featuring double high-temperature silicone O-rings and water cooling jackets to maintain vacuum integrity and thermal stability. The system includes vacuum and pressure gauges, ball valves, and needle valves for precise atmosphere control. The vacuum capability reaches 10-2 torr with a mechanical pump and 10-5 torr with an optional turbopump.
