OTF-1200X-III-HVC-LD Three-Zone Tube Furnace with High Vacuum Station and 4-Channel Mass Flow Controller for CVD up to 1200°C
The OTF-1200X-III-HVC-LD is engineered to support advanced chemical vapor deposition (CVD), diffusion, and other thermal processing tasks requiring precise temperature control and vacuum conditions. It integrates a three-zone tube furnace with a fused quartz processing tube, enabling uniform heating up to 1200°C. This setup is ideal for experiments demanding controlled atmospheres and low-pressure environments.
The system includes a high vacuum station capable of reaching ultimate pressures below 10⁻⁸ mbar (without leaks), ensuring a clean environment for sensitive processes. A 4-channel digital mass flow controller (MFC) allows accurate mixing and delivery of multiple gases into the furnace tube, facilitating complex gas flow profiles essential for CVD and related applications.
Key Features
- Three independent heating zones totaling 900 mm length with PID temperature controllers and ±1°C accuracy.
- Fused quartz processing tube included; tube size selectable as an option.
- High vacuum station with Pfeiffer molecular pump, LCD control panel, and vacuum sensor achieving pressures down to <1E-8 mbar.
- 4-channel mass flow controller with digital LED display, capable of precise gas flow control from 0 to 499 SCCM per channel.
- Double-layer steel casing with automatic air cooling and built-in thermostat for safe operation.
- Heating elements made of Mo-doped Fe-Cr-Al alloy for reliable high-temperature performance.
- Programmable heat-up rate from 1 to 20°C per minute for controlled thermal ramping.

Typical Applications
This furnace workstation is suited for chemical vapor deposition (CVD) processes, diffusion treatments, and other thermal processes requiring precise temperature zones under vacuum or controlled gas atmospheres. It is particularly useful for research and development in thin film deposition, semiconductor fabrication, and materials science.
Configuration & Operating Notes
The system includes one fused quartz tube and a vacuum flange assembly with pressure gauges and valves. Optional accessories such as bubblers or evaporators for CVD can be added separately. Users must calibrate temperature for accuracy and install a two-stage pressure regulator on gas cylinders to limit pressure below 3 PSI to protect the quartz tube. Gas flow rates should be kept below 200 SCCM to minimize thermal shock. Vacuum operation is recommended up to 1000°C for quartz tube safety.
