Three Zones 1200C Vertical Tube Furnace with 2" Quartz Tube & Vacuum Flanges - OTF-1200X-VT-III-50

0.0/5 rating (0 votes)

Description

OTF-1200X-VT-III-50 is Three Heating Zone Split Vertical Tube Furnace with vacuum-sealed 50 mm diameter quartz tube. Not only it can achieve faster sample heating and quench ing in vacuum or gas flow, but also be used for PVD, CSS or CVD coating. Three precision temperature controllers provide 30 segments heating and cooling program with +/- 1°C accuracy independently. The vertical tube furnace is installed in a heavy-duty mobile cart for easy moving.

Application Note ( We may help you to build customized flange to meet your application at extra cost )

  • Customers may calibrate temperature before use to obtain accurate temperature inside the tube furnace,   please click here to learn how.
  • Please click the picture below to learn how to quench sample in gas flow and vacuum
    • Approach#1: Traditional wire cut and free-falling  ( Fig. 1 & 2 )
    • Approach#2: Electromagnetic release and free-falling. (Fig 3 & 4 )

  • The tube furnaces with quartz tube are designed for use under vacuum and low pressure <0.2 bar / 3 psi / 0.02 MPa. 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.
  • 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.
