Specifications
OTF-1200X-II-VT-USPA is Two Heating Zone Split Vertical Tube Furnace with a vacuum-sealed 100mm diameter quartz tube. It can introduce gas flow or liquid/ water atomization to the heating furnace, also be used for PVD, CSS or CVD coating. Two precision temperature controllers provide 30 segments heating and cooling program with +/- 1°C accuracy independently. The vertical tube furnace is installed in a heavy-duty mobile cart for easy moving.

| Application Note |
|
| Warning |
- The tube furnaces with quartz tube are designed for using under vacuum and low pressure <0.2 bars / 3 psi / 0.02 MPa. Vacuum pressures may only be safely used up to 1000°C. The flow rate for gasses should be limited to < 200 SCCM (or 200ml/min) for reducing thermal shocks to the tube.
- Attention: A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 PSI for safe operation. Click here to learn the installation of a gas regulator
