Dilatometers for measuring:

  • CTE
  • Linear Thermal Expansion
  • Alpha Physical
  • Sintering Temperature
  • Phase Transformations
  • Softening Points
  • Decomposition Temperatures
  • Glass Transition Temperatures

The vertical research Dilatometer series L75V was developed to meet the demands of the academic community and research laboratories worldwide. With this system thermal expansion behavior of solids, liquids, powders and pastes for a variety of applications can be precisely determined. The unique vertical design of this system is perfect for low or ultra low expansion materials, since the vertical “Zero-Friction” design guarantees superior measuring results. This line of Dilatometers is capable of performing measurements under vacuum, oxidizing and reducing atmospheres.

This system can be ordered in a single or differential version for even higher precision or sample throughput. Optionally the mechanical and electronic components of the dilatometer can be separated to allow measurements in a glove box.
