Heating Elements

Fe-Cr-Al Alloy doped by Mo

Processing Tube

1" O.D x 0.87" I.D x 24" L Quartz tube or 2.0" O.D x 1.85" I.D  x 24" L quartz tube

• Two fibrous ceramic tube blocks are included for blocking heat radiation generated from 


• tube center. (Ceramic blocks must be fully inserted into the furnace chamber before heating).


• Quartz blocks (optional) are ideal for cleaner processing environment and higher vacuum efficiency.

Vacuum Flange
  

Two choices of stainless steel flange with vacuum gauge and valves

2" default flange with 1/4'' Bard fittings, 1/4'' tube feed through port (for 1/4" O.D thermocouple insert) and a KF25 vacuum port 1" flange has no thermocouple insert.

Optional:

• You may need a vacuum valve at the vacuum port end.


• For fast & better vacuum, we recommend the use of stainless steel pipe, as well as a digital vacuum gauge.  


• You may consider ordering  quick connecting flange at extra cost.

Fitting Ports

• Both flanges will come standard with 3/8" barbed hose fittings


• In order to increase the throughput and achieve a high vacuum, you may replace the standard barbed hose fitting with the KF25 adapter.


• For supplying high-pressure gas, you may replace the standard barbed hose fitting with the 304SS 1/4" Swagelok® Tube Fitting x 1/4" BSPP Male Connector.

Vacuum Pressure

• 50 mtorr can be achieved by mechanical pump


• 10^-5 torr can be reached by molecular pump    

Pressure Measurement / Monitoring

• Mechanical Vacuum Gauge (included as standard accessory), which  measures within a pressure range of -0.1 to 0.15Mpa.  


• Digital Pressure Gauge (optional): A gas-type independent (above 10mbar) digital vacuum gauge with a wide range between 3.8x10^-5 to 1125 Torr. Aside from greater measurement precision, this gauge reduces risks of chamber explosions caused by incorrect reading of gas pressures due to gas-type dependency.

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


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