Dilatometer – DIL

Expansion Measurement / Sintering processes / Contact angle

Linseis produces a wide range of single, dual, differential, quattro, quenching, laser and optical dilatometers in a temperature range from -263 °C to 2800 °C and a resolution down to 0.3 nm. Thanks to our long experience (since 1953), Linseis offers dilatometers with unsurpassed performance.

Dilatometers are widely used for research and development as well as for quality control of solids, liquids, powders and pastes to determine:

Determination of coefficient of thermal expansion (CTE)
linear thermal expansion (ΔL)
sintering temperatures and sintering steps
determination of the glass transition (Tg)
phase change
optimization of firing processes
Volume changes
Rate Controlled Sintering (RCS)
Decomposition
Density change

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

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

Vertical arrangement

Zero friction design (the specimen is in contact only with the end stop and the push rod).
Multiple furnace arrangement (up to three furnaces):
- to cover the whole temperature range from -180 to 2800°C, especially ideal for low and very high temperatures
- to avoid convection
Perfect for low temperature measurements (furnace at the bottom - measuring compartment at the top) to ensure access to the gas, cold air (falling down) under the sensor area
Perfect for high temperature measurements (furnace on top - measuring compartment on bottom) to ensure access to the gas, hot air (flows upwards) above the sensor area
Small footprint and low requirements for laboratory space
Available as single, differential/double and quattro arrangement (1, 2 or 4 samples simultaneously)
