Vacuum Flanges

• SS water-cooled flanges on both sides. 
• Left flange:
  1/4" thermocouple feedthrough
  1/4'' tube fitting
• Right flange:
  KF 25 port with a right angle gate valve for vacuum pump
  Needle valve with barb fitting as a venting port
• A digital vacuum gauge is included
• Retractable bellow design is optional on the left flange, which allows sample flash heating or retrieving for fast cooling under inert gas. 

Vacuum Level

•  Limited by the vacuum pump
• 10^-2 torr can be achieved by the mechanical pump
• 10^-4 torr can be reached by molecular pump
• The pump is not included. ( please click the picture below to order )

Water Chiller (optional)

• Cooling water is required for the flange set.
• Please make sure the flow rate of cooling water is ≥ 10L/min, water temp. < 25ºC; pressure > 25 PSI.
• We suggest EQ-KJ5000 Series recirculating water chiller as a cooling system (please order separately at related products below).

Laptop, software & WiFi Control (Optional)

• Brand new laptop with Microsoft Windows 10 and Microsoft Office 2013 (30 days free trial) for immediate use.

• A wireless remote control provides up to 300 meters of operating range.
• The features above are available upon request at an extra cost (up to $1,000). Please contact us for more information.
• Note: The software is only compatible with MTI’s Yudian Temperature Controller

• 

Compliance

• CE Certified
• NRTL(UL61010) or CSA certification is available upon request at extra cost. （ please click marks below to learn details )

Application Notes

Click here to learn the installation of a gas regulator

• Tube furnaces with quartz tubes are designed for use under vacuum and low pressure < 0.12 MPa (absolute pressure).
• 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.
• The flow rate for gasses should be limited to < 200 SCCM (or 200 ml/min) for reducing thermal shocks to the tube
• Vacuum limit definition for all quartz tube furnaces: * Vacuum pressures may only be safely used up to 1000°C
• Click here to learn how to set up a quartz/ ceramic tube and vacuum flange for MTI Tube furnace.
• Quartz tubes should be replaced after every 10th use to ensure the best performance. 
• Samples should never be placed on the tube directly; please order crucibles and boats from here.
• 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 below.
