The horizontal Dual- and differential- Dilatometer (DIL) series L75H 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 design of this system guarantees highest precision, reproducibility and accuracy. This line of Dilatometers is capable of performing measurements under vacuum, oxidizing and reducing atmospheres.
This system can be ordered in a single, dual 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.
With our automatic pressure control, the contact pressure can be continuously varied between 10 and 1000mN, depending on the application. This feature continuously controls the selected contact pressure throughout expansion and/or shrinkage of the sample.
The following physical properties can be measured:
CTE, Linear Thermal Expansion, Alpha Physical, Sintering Temperature, Phase Transformations, Softening Points, Decomposition Temperatures, Glass Transition Temperatures.
Specifications:
* dependent on furnace
Software:
All LINSEIS thermo analytical instruments are PC controlled. The individual software modules exclusively run under Microsoft® Windows® operating systems. The complete software consists of 3 modules: temperature control, data acquisition and data evaluation. The 32 bit software incorporates all essential features for measurement preparation, execution, and evaluation of a Dilatometer measurement. Thanks to our specialists and application experts, LINSEIS was able to develop comprehensive easy to understand user friendly application software.
Applications:
Polymers, Ceramic/Glass/Building Materials, Metals/Alloys, Inorganics
Ceramics, Building Materials and Glass Industry, Automotive / Aviation / Aerospace, Research, Development and Academia, Metals / Alloys Industry, Electronics Industry
The thermal expansion of rock crystal can be easily evaluated with the L75 Dilatometer. The additional DTA feature enables an in depth view of the thermal behavior of the material. The DTA measurement is a mathematical routine based on the sample temperature. Exo- and endothermic effects influence the change of the sample temperature during the dynamic heating or cooling cycle. At app. 575°C the phase transition from takes place. The deviation of the measured temperature from the literature value (574°C) can be used for a temperature calibration.
The linear thermal expansion (delta L) and the CTE of the iron sample under argon atmosphere are evaluated. The heating rate was 5K/min. After 736.3°C (peak temperature of CTE) shrinkage was detected, this is due to a change in the atomic structure, known as the curie-point. The difference of measured and literature result can be attributed to contamination of the sample.
