Specific Introduction:
The KJ-1200X-HVC series furnace workstation consists of an OTF-1200X series tube furnace, a precision mass flow gas control station, a high vacuum station, and other assembling parts. The max. working temperature of this workstation is 1200°C. The ultimate vacuum rate goes to 10^-4 torr (with our sealing assembly provided). The mass flow gas control station mixes three kinds of gas together and allows the mixed gas to flow into a fused quartz tube inside the furnace. It is competent for the experiments as CVD, Diffusion and other thermo-treatments under vacuum status and shielding gas protected.

Warning	The tube furnaces with quartz tube are designed for use under vacuum and low pressure < 0.2 bars 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 gases should be limited to < 200 ml/min for reducing thermal shocks to the tube Vacuum pressures may only be safely used up to 1000°C
Warranty	One year limited warranty with lifetime support (Consumable parts such as processing tubes, O-rings are not covered by the warranty, please order replacements at related products page.)
