OTF-1100X-III Three-Zone Tube Furnace with 11″ or 15″ Quartz Tube, Hinged Flanges, and Motorized Lid Actuators, Up to 1100°C
The OTF-1100X-III is engineered for advanced laboratory applications requiring precise thermal processing of bulk samples and wafers. It excels in tasks such as materials synthesis, wafer annealing, diffusion, and heat treatment under vacuum or controlled gas atmospheres. The furnace’s design supports continuous operation at temperatures up to 1100°C, with short-term capability up to 1200°C, providing flexibility for various thermal protocols.
This model incorporates a split tube structure with a choice of 11″ or 15″ outer diameter quartz tubes, each 73″ in length, facilitating compatibility with different sample sizes and experimental setups. The furnace lid is equipped with motorized actuators, enabling smooth and safe opening and closing. Temperature control is managed by three programmable PID controllers, allowing segmented temperature profiles with high stability and accuracy within ±1°C, ensuring uniform heating across the 900 mm total heating length.
