The temperature controller
Eurotherm 3000 Series optional
Processing Tube
  • Premier Grade alumina tube.
  • 54 mm (I.D) x 60 mm (O.D) x 800 mm length.
  • Four fibrous ceramic tube blocks are included for blocking heat radiation from inside tube. (Ceramic blocks must be fully inserted into the furnace chamber before heating).
  • For 60mm tubes, it is recommended that customers purchase two pairs of tube support to prevent the tube from bending under high temperature (please click on the last picture to order).

Sealing Flanges
  • One pair sealing flange with double silicone high-temperature O-ring is included.  
  • Two SS needle valves and one dial vacuum gauge are installed with flange for immediate use. 
  • Vacuum pressure can reach 50 mTorr by a quality mechanical vacuum pump and 10^-5 torr by turbo molecular pump. Please click the picture below to see flange assembling details. 

Fitting Ports

Vacuum Level
  • Limited by vacuum pump
    • 50 mtorr can be achieved by mechanical pump
    • 10^-5 torr can be reached by molecular pump
  •  Vacuum pump is not included, please order separately by clicking here
Pressure Measurement / Monitoring
  • Mechanical Vacuum Gauge (included as standard accessory). This mechanical vacuum gauge measures within a pressure range of -0.1 to 0.15Mpa.  
  • Digital Pressure Gauge is 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 the incorrect reading of gas pressures due to gas-type dependency. 
Power Cable & Plug
  • 10 feet length 10-3 AWG heavy duty UL approved power cable is included. Extra length cable can be ordered by click picture below-left
  • The plug is not included. Browse our catalog for compatible plugs or obtain one from local hardware store.
