OTF-1200X-IR-IISL is a dual-zone IR heated RTP tube furnace with 4" ID quartz tube and slidable sample holder for easy operation. It is capable of achieving a max. the heating rate of 50°C/s and a cooling rate of 117°C/min. The furnace is designed for growing two-dimension materials via HPCVD, where one heating zone is used as a solid evaporating source and another zone for sample deposition..

Application NotesClick here to learnthe installation of a gas regulator	、Tube furnaces with quartz tubes are designed for use under vacuum and low pressure ＜ 0.12 MPa (absolute pressure). 、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 learnthe installation of a gas regulator. 、The flow rate for gasses 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 、Click here to learnhow to set up a quartz/ ceramic tube and vacuum flange for STR-Tube furnace. 、Quartz tubes should be replaced after every 10th use to ensure the best performance. 、Samples should never be placed on the tube directly; please order crucibles and boats fromhere. 、After CVD, the graphene must be transferred from the metal catalyst to another substrate for most applications. By using the graphene transfer tape, the residue can below.
