OTF1200XHP55 High Pressure Oxygen Tube Furnace with 20mm ID Ni-Based Superalloy Tube, Up to 1100°C at 610 PSI
The OTF1200XHP55 is engineered for advanced laboratory applications requiring controlled high-pressure and high-temperature environments. It is particularly suited for the synthesis and treatment of special compounds under oxygen and inert gas atmospheres, enabling researchers to prepare novel materials and perform mini hot isostatic pressing (HIP) on metallic samples.
This split tube furnace incorporates a nickel-based superalloy processing tube with a 20 mm internal diameter and 55 mm outer diameter, designed to withstand pressures up to 7 MPa (approximately 1015 PSI) and temperatures reaching 1100°C. The furnace features precise temperature control with a programmable PID system and integrated pressure monitoring with safety alarms and automatic pressure relief mechanisms.
Key Features
- Ni-based superalloy tube (Waspaloy or equivalent) with 20 mm ID and 580 mm length for high-pressure operation.
- Maximum operating temperature of 1100°C with heating rates up to 30°C/min.
- Pressure capability up to 610 PSI (4.2 MPa) at 1100°C, with higher pressures allowed at lower temperatures.
- Double-layer steel casing with air cooling and high-purity alumina insulation for energy efficiency.
- Integrated precision pressure sensor and digital display with alarm and automatic pressure relief valve.
- PC control via included laptop and pre-installed software for remote temperature and pressure monitoring.
- Compatible with oxygen and inert gases (N2, Ar, He) and requires use of crucibles or isolated foil to protect the tube from sample contamination.

Typical Applications
This furnace is used for high-pressure oxygen and inert gas treatments in material science research, including hydroretorting of shale oil, synthesis of advanced ceramics, and mini hot isostatic pressing of metals. It supports experiments requiring precise atmosphere control and elevated temperature and pressure conditions.
Configuration & Operating Notes
Samples must be loaded inside a quartz or alumina crucible or wrapped in isolated foil to prevent reaction with the Ni-based tube. Over-tightening flange bolts should be avoided; a torque wrench is recommended to apply the specified 40-foot pound torque. The furnace includes safety features such as pressure alarms and automatic pressure relief valves. Optional accessories include high-pressure electrical feedthroughs and sapphire windows for optical access.
