The size of the glove box, the number and size of the air locks and the number of gloves suit the customer’s requirements.

  • Tube furnaces up to 1800°C
  • Chamber furnaces up to 3000°C
  • All glovebox sizes available
  • Front loading furnace
  • Bottom loading furnace from ceiling of glove box

The atmospheres and pressures inside the glove box are limited by the built standards of general glove box constructions. Most customers choose either nitrogen or argon in a slight over pressure for the glove box atmosphere to protect the samples from oxidation. Alternatively underpressure for personnel protection is also available.

The two most popular furnace loading concepts are:

  1. horizontal loading of the furnace chamber through the side or back wall of the glove box
  2. vertical loading of the furnace chamber with a furnace above the glove box. An automated mechanism moves the sample into the glove box.
