Compact Vertical Split 1" or 2" Quartz Tube Furnace with SS Vacuum Flanges - OTF-1200X-S-VT

MTI

OTF-1200X-S-VT is a compact-split vertical tube furnace with vacuum-sealed 1", 2" or 2.36" (60mm) diameter quartz tube. It provides fast heating and quenching as well as the capability to heat samples under vacuum or flowing gas atmospheres. A precision temperature controller can provide up to 30 segments of the heating, cooling, and dwelling steps with +/- 1ºC accuracy. It is an ideal furnace for carrying out quenching tests.

  • A wireless remote control provides up to 50 meters of operating range.

Compliance
  • CE certified
  • NRTL or CSA certification is available upon request at the extra cost

Warning
  • Tube furnaces with quartz tube are designed for using under vacuum and low pressure < 3 psig. 
  • Attention: A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 PSIG for safe operation.
  • Vacuum pressures may only be safely used up to 1000°C 
  • The flow rate for gasses should be limited to<200 SCCM  for reducing thermal shocks to the tube
