Heating Elements

Fe-Cr-Al Alloy doped by Mo

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 the tube center. (Ceramic blocks must be fully inserted into the furnace chamber before heating).
• Quartz blocks (optional) are ideal for clean processing environments and higher vacuum efficiency.

• Two choices of stainless steel flange with vacuum gauge and valves
• 2" default flange with 1/4'' Bard fittings, 1/4'' tube feedthrough port (for 1/4" O.D thermocouple insert), and a KF25 vacuum port (click the bottom right picture to see details)
• 1" flange has no thermocouple insert (click the bottom left picture to see details)        
• Optional:
• May need a vacuum valve at the vacuum port for 2' Flange Set (click picture left to order)
• For a fast & better vacuum, we recommend the use of stainless steel pipe (click to order at extra cost), as well as a digital vacuum gauge
  
• You may consider ordering a quick connecting flange at an extra cost
• Click on the furnace picture (lower right) below to see how to insert an external thermocouple; additional furnace accessories are available for purchase.
•              

• 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 (please click the underline to order).
• 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 (please click the underline to order).        

Vacuum Pressure

• 50 m-torr can be achieved by a mechanical pump
• 10^-5 torr can be reached by molecular pump
      

Pressure Measurement / Monitoring

• A mechanical Vacuum Gauge is included which measures within a pressure range of -0.1 to 0.15Mpa.  
• Digital Pressure Gauge (optional): A gas-type independent (above 10 mbar) 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 the incorrect reading of gas pressures due to gas-type dependency
