Dilatometer

Dilatometry / Expansion Measurement / Dilatometer (DIL)

Linseis produces a wide range of Single-, Dual-, Differential-, Quattro-, Quenching-, Laser- and Optical Dilatometer in a temperature range from -263°C up to 2800°C and a resolution up to 0.3 nm. Thanks to our years of experience (est. 1953), Linseis offers Dilatometers with an unbeaten performance.

Dilatometers are frequently used for R&D and quality control of solids, liquids, powders and pastes to determine their:

  • determination of thermal expansion coefficient (CTE)
  • linear thermal expansion (ΔL)
  • sinter-temperatures and sinter steps
  • determination of glass transition (Tg)
  • phase changes
  • optimization of burning processes
  • volume changes
  • Rate Controlled Sintering (RCS)
  • decomposition
  • density change

Dilatometry (DIL) is a technique in which a dimension of a substance under negligible load is measured (e.g. expansion measurement or shrinkage measurement) as a function of temperature while the substance is subjected to a controlled temperature program in a specified atmosphere.

Horizontal vs. Vertical Design

Horizontal arrangement

  • Easy and robust design at a modest price
  • Perfect choice for mid temperature range
  • Easy sample handling
  • Customized Dilatometers for huge samples available
Push rod Dilatometer from Linseis Thermal Analysis

Horizontal Design

Linseis Quattro Dilatometer

Vertical Design

Vertical arrangement

  • Zero friction design (sample is only in contact with the end knob and the pushrod)
  • Multi-furnace arrangement (up to three furnaces)
    • to cover entire temperature range from -180 to 2800°C especially ideal for low and
      very high temperatures
    • to increase throughput (hot furnace can be lifted automatically to switch to new cold furnace and start new measurement)
  • perfect for low temperature measurements (furnace on the bottom – measurement compartment on top) to ensure natural gas path, cold air (falls down) below sensor compartment
  • perfect for high temperature measurements (furnace on top – measurement compartment below) to ensure natural gas path, hot air (streams up) above sensor compartment
  • Small footprint and Small lab space requirements
  • Available as single-, differential/double- and quattro arrangement (1, 2 or 4 samples at the same time)
