Application NotesClick here to learnthe installation of a gas regulator

、Tube furnaces with quartz tubes are designed for using under vacuum and low pressure ＜ 0.2 bars / 3 psi / 0.02 Mpa 、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 quartz/ ceramic tube and vacuum flange for STR-Tube furnace. 、One slide stopping clamp is included for holding the position of the furnace. 、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 be low.

Warning

Fast sample cooling can be achieved by sliding the heating chamber away. Please wear protective gears such as heat resistant suit amp; gloves if you intend to do so. DO NOT TOUCH THE TUBE SURFACE WHEN IT IS HOT!
