Application Notes
|
-
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.
-
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
-

-
If you need faster cooling please click the picture below to order a Portable Spot Air Cooling Conditioner .
-
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.
-
For Horizontal directional crystalization (HDC), you may use a gas feedtrough as pic below right.
-
 
|
|
Warning
|
-
Fast sample cooling can be achieved by sliding the heating chamber away. Please wear protective gears such as heat resistant suit & gloves if you intend to do so.
-
DO NOT TOUCH THE TUBE SURFACE WHEN IT IS HOT!
