Item Number: OTF1200XSF2V110
Transported by LTL Freight (Truck)

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.
