Compact Split Tube Furnace with Insert-able Temp Calibrator and Complete Vacuum System - OTF-1200X-S50-LVT

0.0/5 rating (0 votes)


Product Number: OTF-1200X-S50-LVT


OTF-1200X-S50-LVT high temperature vacuum tube furnace is a split tube furnace for heating samples up to 1200°C. KF25 Gas Outlet and Digital Vacuum Gauge on the right flange connecting a 226L/m Mechanical Pump and Pump Filter while 1/4'' barb gas inlet on the left, allows the furnace to heat sample in vacuum upto 1E-2 Torr or flowing gas. In addition, OMEGA 1/4’’ O.D K Type Thermal Couple comes to the left flange, can be inserted inside the tube to exactly measure the sample’s temperature by the readout from the OMEGA Calibrator. Precision temperature controller will provide 30 segments heating and cooling steps with +/- 1 °C accuracy.

Application Notes

  • Tube furnaces with quartz tubes are designed for using under vacuum and low pressure < 0.2 bar / 3 psi / 0.02MPa
  • Attention: A two stage pressure regulator must be installed on 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 gases should be limited to<200 SCCM (or 200ml/min) for reducing thermal shocks to the tube
  • How to set up ceramic tube and vacuum flange for MTI tube furnaces.
  • For safety, you may consider to put the small tube furnace inside a humehood. ( click picture left to see )
  • Furnace is ready to pass UL 61010, IEC 61010, SPE-1000 tested by NRTLs at extra cost. 
  • Vacuum Pump:  CE Certified only
