  • The sample holder is removable from the flange for using the RTP furnace for other purposes.


Vacuum Flange
  • KF-D25 High Vacuum Flange is made of stainless steel with double hi-temp. silicone O-rings, needle valves, and water cooling jacket.
  • Only requires water cooling in long running times at temperatures > 600oC.
  • Circulating water rate: 0.5 m3 /hr.
  • The slide-out flange provides an easier way of loading, unloading the samples and other specific process needed.
  • Insert-able thermal-couple for accurate measurement.
Vacuum Pump  (optional)
  • EQ-FYP vacuum pump is recommended for this furnace. The ultimate vacuum pressure in this system can be 10^-3 torr. Vacuum bellows and clamps are included in this package. Click here for the spec of EQ-FYP vacuum pump.
Water Cooling  (optional)
  • Cooling water is required.
  • Please make sure the flow rate of cooling water is ≥ 10L/min, water temp. < 25ºC; pressure > 25 PSI.
  • We suggest using the EQ-KJ5000 Series recirculating water chiller as a cooling system (please order separately at related products below) to save water.
  • Warning: This RTP furnace’s max dwelling time shall be less than 600 seconds at 1000ºC ~ 1100ºC with tap water, otherwise O-ring may melt.

  • You may combine the RTP furnace with high vacuum station or gas livery system as vacuum furnace or CVD system. Click pictures below to see details
  • For achieving fast cooling rate (< 10ºC/second), you may choose RTP furnace with sliding rail. Please click the picture below to see details.
  • You may order pressure control module.
Application Notes

  • Tube furnaces with quartz tubes are designed for using under vacuum and low pressure < 0.2 bars / 3 psi / 0.02 MPa. Vacuum pressures may only be safely used up to 1000°CThe flow rate for gasses should be limited to<200 SCCM (or 200ml/min) for reducing thermal shocks to the tube
  • Attention: A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 PSI for safe operation.  This furnace also can be modified into an RTE, CSS or HPCVD  furnace with a graphite crucible coated with SiC ( click Pic-left for detail how to set up an RTE processing by DIY )
  • 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.
