Temperature Control

1.     PID automatic control with 30 programmable segments for precise control of heating rate, cooling rate and dwell time.

2.     Built-in over temperature alarm and protection allows for operation without an attendant.

3.     Two K-type thermal couples are included.  One is built in the furnace to control furnace temperature, and another inserted into the tube to monitor sample real temperature profile.

4.     PC control module is included. 

Temperature Accuracy

+/ - 1°C

Vacuum Flanges

Stainless steel vacuum flanges are installed on both ends of the tube with heavy duty support. 

• Right flange:  KF-25 pump connector and needle valve.
• Left flange: one needle valve and 1/4" thermocouple feed-through and digital vacuum gauge.
• An 24" length x 1/4" Dia. K type thermocouple (included) connected to an Omega temperature calibrator (included) will be inserted through this flange to monitor the heating and cooling rates of the sample's position during furnace sliding.

Application Notes

1.     Tube furnaces with quartz tubes are designed for using under vacuum and low pressure <  0.2 bars / 3 psi / 0.02 MPa

2.     Attention: A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 PSI for safe operation. 

3.     The flow rate for gasses should be limited to < 200 SCCM (or 200 ml/min) for reducing thermal shocks to the tube

4.     Vacuum limit definition for all quartz tube furnaces: * Vacuum pressures may only be safely used up to 1000°C.

5.     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.
