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 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.

•      •  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 bottom right picture to see details )
•      •  1" flange has no thermocouple insert ( click bottom left picture to see details )   
      

Optional:

•      •  May need a vacuum valve at the vacuum portend  for 2' Flange Set ( click picture left to order )
•      •  For 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 quick connecting flange at extra cost.
•      •   Click on 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 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

Warranty

• 
       •  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. 
        Click here to learn the installation of a gas regulator.
  
•      •  Vacuum limit definition for all quartz tube furnaces: * Vacuum pressures may only be safely
          used up to 1000°C
•      •  The flow rate for gasses should be limited to<200 SCCM (or 200ml/min) for reducing
           thermal shocks to the tube
