OTF1200XSVT-NT Vertical Split Tube Furnace with Temperature Controller
The OTF1200XSVT-NT is engineered for laboratory processes that require controlled high-temperature environments within tubular reactors. Its vertical split furnace design allows users to install and replace processing tubes of 1″ or 2″ outer diameter conveniently, supporting custom tubular reactor setups without a pre-installed processing tube. This flexibility is ideal for research and development tasks involving high-temperature material synthesis or thermal treatments.
The furnace achieves a maximum temperature of 1100°C for short durations and can maintain continuous operation at 1000°C. The heating zone extends 200 mm in length, with a stable constant temperature zone of 60 mm, controlled within ±1°C. The heating element is a Fe-Cr-Al alloy doped with M, providing reliable and uniform heating. The double-layer steel structure with air cooling and high-purity alumina fibrous insulation ensures energy efficiency and safety.
Key Features
- Vertical split design for easy tube installation and replacement without removing the entire furnace.

Typical Applications
Ideal for laboratory-scale tubular reactor experiments requiring precise temperature control up to 1100°C. Suitable for materials research, catalyst testing, thermal treatment of powders or fibers, and custom reactor assembly where tube replacement flexibility is essential.
Configuration & Operating Notes
The furnace is supplied without a processing tube; users must select and install their own 1″ or 2″ diameter tube, available in stainless steel or super-alloy options. Tube adapters are recommended to insulate thermal radiation at furnace ends. An advanced temperature control software kit with a 15″ laptop is optionally available for enhanced process programming and monitoring. Proper handling and installation of tubes and adapters are essential to ensure safety and optimal thermal performance.
