Application Notes
  • For longer tube service life, please use alumina, BN or zirconia crucibles to carry samples instead of put loading directly onto the tube. Please click pic.1 in below to choose crucibles.
  • You may need a water cold flange with proper support for the alloy tube due to high thermal conductivity. Please click pic.2 in below to order.
  • You may use the alloy tube with our three-zone tube furnaces for materials sintering, annealing applications, please click pic.3 for more details  
  • Datasheet, please click the underline to see detailed specs.
