1200C Dual Zone Split Tube Furnace w/ Quartz Tube (60, 80, 100mm) & Flanges - OTF1200XII

OTF-1200X-II-UL is a Split two-zone tube furnace that can achieve faster heating up to 1200 o C and create a different thermal gradient by setting the different temperatures of each zone. The furnace includes one 40" L fused quartz tube ( please select tube O.D in the options bar ) with vacuum flanges and valves for immediate use. Two 30 segments of programmable temperature controllers are installed. The microprocessor-based self-tuning PID controller provides excellent control without overshooting the set temperature. It is a perfect tool for CVD applications such as preparing nanomaterials and film.

Application Notes Click here to learn the installation of a gas regulator.	Click here to learn How to set up a quartz/ ceramic tube and vacuum flange for MTI Tube furnace. (Click the picture below to see the demo video) Tube furnaces with quartz tubes are designed for use under vacuum and low pressure < 0.2 bars / 3 psi / 0.02 MPa.Vacuum pressure may only be safely used up to 1000°C. The flow rate for gasses should be limited to < 200 SCCM (or 200 ml/min) for reducing thermal shocks to the tube. Attention: A two-stage pressure regulator must be installed on a gas cylinder to limit the pressure to below 3 PSI for safe operation. Click here to learn the installation of a gas regulator.
