0.0/5 rating (0 votes)

Description

Product Number: OTF-1200X-50-III-VT-UL

 

OTF-1200X-50-III-VT-UL 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 quenching 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.

Operation Instructions

         

 Warning

  • The tube furnaces with quartz tube are designed for using 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 gas cylinder to limit the pressure to below 3 PSI for safe operation. Click here to learn the installation of a gas regulator.
