OTF1700X12Z 12-Zone Split Tube Furnace with Ø100 mm × 1800 mm Alumina Tube, Up to 1700°C
The OTF1700X12Z furnace is engineered for laboratory applications requiring precise spatial temperature control along an extended heating zone. It is especially suited for simulating reactive kinetics and mechanisms by establishing variable temperature gradients within a long alumina tube. This capability enables detailed thermal profiling and controlled reaction environments under ambient or vacuum conditions.
The furnace incorporates a 12-zone split heating design with individual PID temperature controllers, allowing independent regulation of each zone. The heating length totals 1400 mm within an 1800 mm long alumina tube of 100 mm outer diameter. The tube supports operation up to 1700°C at ambient pressure and up to 1450°C under vacuum, making it versatile for high-temperature material processing and research.
