OTF-1200X-S50-2F Mini CVD tube furnace is a CE Certified split tube furnace for heating samples up to 1200°C. A KF25 Gas Outlet and a Digital Vacuum Gauge are installed in the right flange for connection with a 226L/m Mechanical Pump (with Pump Filter). The left flange is used to connect a 2 channel gas mixing station through the 1/4" gas pipe. The precision temperature controller will provide 30 segments of heating and cooling steps with +/- 1 °C accuracy. This furnace system also includes an anti-corrosive Pirani Capacitance Diaphragm Gauge to enable vacuum measurements with aggressive gases. In addition, you can get an accurate pressure reading with any mixed gases via the Digital Vacuum gauge.

In order to obtain an accurate temperature inside the tube furnace, you need to calibrate the temperature by yourself. Pls, click here to learn how. How to set up a ceramic tube and vacuum flange for MTI Tube Furnace. Warning: Tube furnaces with quartz tube are designed for use with a vacuum and low pressure < 0.2 bar / 3 psi  Vacuum limit definition for all quartz tube furnaces: * Vacuum pressures may only be safely used up to 1000°C The flow rate for gases 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 the gas cylinder to limit the pressure to below 3 PSI for safe operation. Click here to learn the installation of a gas regulator.
