• Limited by the vacuum pump
  • 50 mtorr can be achieved by the mechanical pump
  • 10^-5 torr can be reached by molecular pump

•  The vacuum pump is not included, please order separately at the related products section

• 10 feet length 10-3 AWG heavy duty UL approved power cable is included. Extra length cable can be ordered by click the picture below-left
• The plug is not included. Browse our catalog for compatible plugs or obtain one from a local hardware store

• CE Certified
• NRTL or CSA certification is available upon request at extra cost.

• In order to obtain accurate temperature inside the tube furnace, you need to perform a temperature calibration before use, please click here to learn how.
•  Vacuum pressures may only be safely used up to 1500 °C
• The tube furnaces with alumina tube are designed for use under vacuum and low pressure < 0.02 MPa (absolute pressure)
• Attention: it is necessary to install the gas pressure regulator to reduce the output pressure 3 PSI, avoid over pressurizing the furnace chamber, and ensure safe operation. Click here to learn the installation of a gas regulator.
• The flow rate for gases should be limited to < 200 ml/min) for reducing thermal shocks to the tube

Two fibrous ceramic tube blocks are included for blocking heat radiation from inside the tube (Ceramic blocks must be fully inserted into the furnace chamber before heating).
