L74 Optical Dilatometer

Research Optical Microscope Dilatometer series – CTE

Description

On point

The Optical Research Dilatometer L74 was developed to meet the demanding applications of the glass, ceramics, metal and energy industry. A high resolution CCD camera enables a visual real time analysis of the sample expansion, either as single frame or as video sequences.

The big advantage of this method is that the sample is not burdened with any force. For soft samples or samples that melt during the measurement, this leads to a result, which is not distorted by the contact pressure.

Several correction and analysis features are incorporated into the LINSEIS Evaluation Software. The unique horizontal design enables most demanding applications.

The special solid-liquid adapter allows expansion / volume measurements of solids, liquids and solid – liquid phase transitions.  There is also a special sample holders for measuring rigid foils available, which avoids measurement errors due to pushrod forces like in a classical dilatometer.

Features

  • Non contact Expansion measurement
  • High resolution CCD camera
  • Heating microscope
  • Optical Fleximeter
  • Sessile Drop
  • Contact angle
  • Solid- liquid expansion (optional adapter)

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.
