Graphene-Growing CVD System



KJ-1200-S6014LK1-H CVD System consists of a tube furnace, a three-channel gas-mixing unit with mass flow meters, a vacuum pump unit.

Range of Application:
This CVD system is specially designed for graphene growth and also for other CVD experiments which require fast heating and cooling. The hot furnace chamber can be pushed directly to the cold side to fast-heat the samples and also the opposite way for fast cooling.

Gas-Mixing Unit with mass flow meters

Three precise mass flow meters (0.02% accuracy) are installed to control gas flow rate with touchscreen control for easy operation.

One gas mixing tank is installed on the bottom case.

MFC 1: Gas flow range from 0~100 SCCM

MFC 2: Control range from 0~200 SCCM  

MFC 3: Control range from 0~500 SCCM

Gas inlet fitting: four 1/4NPS.

Gas outlet fitting: four 1/4NPS.

Power: 185-220VAC 50/60Hz

4 stainless steel needle valves are installed on the left side to manually control the inlet and outlet of gas.

Chiller (Optional)

Be used to cool the tube and vacuum pump.


Pressure higher than 1.02Mpa will break the tube.

Since the pressure in the gas cylinder is high, a converter is necessary. The measurement range of our converter is 0.01mpa-0.1mpa, will ensure a safe gas supply.

No vacuum condition is allowed when the temperature is higher than 1000℃.

Please keep the gas flow lower than 200sccm when the temperature is high to lower the impact of cold air to the hot tube.

If you have to keep the valves on the two ends of the tube closed at the same time, please watch the pressure gauge and open the valves once the pressure is higher than 1.02Mpa to avoid any tube breakage.


One year with lifetime technical support.
