• Built-in protection for the over-heated and broken thermocouple.
• Temperature Accuracy: +/- 1°C
• K-type thermocouple.

Laptop, software & WiFi Control (Optional)

• Brand new laptop with Microsoft Windows 10 and Microsoft Office 2013 (30 days free trial)
• Labview Based Temperature Control System (MTS01)enables users to edit temperature profiles, manage heat-treatment recipes, and record, and plot data for MTI furnaces.

Heating Elements

• Fe-Cr-Al Alloy doped by Mo

• Choice of processing tube
  • 1" O.D x 0.87" I.D x 24" L Quartz tube
  • 2.0" O.D x 1.85" I.D x 24" L quartz tube

• Two fibrous ceramic tube blocks are included to block heat radiation from the hot zone.
• 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

Compliance

        

• CE Certified
• NRTL or CSA certification is available at an extra cost 

Application Notes

• Tube furnaces with quartz tubes 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. 
  
• Vacuum pressures may only be safely used up to 1000°C
• The flow rate for gasses should be limited to 200ml/min for reducing thermal shocks to the tube
