The OTF-1200X-III-HVC series furnace workstation consists of an OTF-1200X-III series three-zone tube furnace, a precision mass flow gas control station, a high vacuum station, and other assembling parts. The max. working temperature of this workstation is 1200°C. The ultimate vacuum rate goes to 10^-4 torr (with our sealing assembly provided). The mass flow gas control station mixes several kinds of gas together and inputs the mixed gas into a fused quartz tube inside the furnace. It is competent for the experiments as CVD, Diffusion, and other thermo-treatments under vacuum status and shielding gas protection. The furnace comes with a 4-channel digital LED display mas flow gas control station.

Notes	- Please click here to see our typical temperature profile calibration result at various temperatures. - In order to obtain accurate temperature inside the tube furnace, you need to calibrate temperature by yourself. Please click here to learn how. - How to set up a ceramic tube and vacuum flange for the MTI Tube furnace.
Warning Click here to learn the installation of a gas regulator	The tube furnaces with quartz tube are designed for use under vacuum and low pressure < 0.2 bar / 3 psi Attention: A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 PSI for safe operation.  The flow rate for gases should be limited to < 200 SCCM (or 200 ml/min) for reducing thermal shocks to the tube Vacuum limit definition for all quartz tube furnaces: * Vacuum pressures may only be safely used up to 1000°C
