Vertical Tube Furnaces

Deltech Vertical Tube Furnaces have been the favorite of petrologists since 1973 when NASA selected Deltech to design and build vertical tube quench test furnaces for petrologic studies of the moon rocks. The descendants of that design are widely used in geosciences research labs around the world.

Customer Comments

“The vertical tube furnace is working fantastically and is a great piece of equipment.“

Features

  • Single and multi-zone designs. Each zone is individually temperature controlled.
  • Sustained operating temperatures up to 1800 degrees Celsius.
  • Specify tube size up to 4” / 10 cm O.D. and hot zone length up to 36” / 91 cm.
  • Mullite tubes are very good for thermal shock resistance, and can be used at operating temperatures up to 1600 degrees Celsius. Above that, 99.8% alumina tubes are required to prevent creep.
  • Bottom loading vertical tube design (VTOSD) for applications in which a load platform is required, such as when the material to be heated in inert gas needs to be placed in a small crucible.
  • Optional water cooled end caps create exceptional gas seals and allow shorter tubes to be used. Shorter tubes have greater resistance to thermal shock.
  • Optional gas mixing and delivery systems include mass flow controllers, software driven digital control system, optional fluid distribution header.
