The Linseis LFA 1000 Laser Flash is the most modular and precise Instrument for the determination of Thermal Diffusivity, Conductivity and Specific Heat Values. Its sample robot for up to 6 Samples at the same time allows unbeaten turnaround times. The three user exchangeable furnaces allow measurements from -125 up to 2800°C.
A number of different sample holders for applications such as solids, liquids, melts and slags are available. The compact design allows the separation of hardware and electronics as well as the installation under a hood for nuclear applications.

Application Example: Copper / Aluminum
The pure metals Copper and Aluminum are used in this example to demonstrate the performance of the Linseis Laser Flash device. The measurement results of the two materials are compared with literature values. The measured results vary within 2% of the given literature values; this demonstrates the excellent performance of the instrument.
Standard Laser Flash reference material Pyroceram 9606. Military – transparent to radar Tops for hot plates and stirrers. Unlike metal tops, glass ceramic is easy to clean, highly resistant to scratches, corrosion and chemical attack.
Isotropic Graphite (AIST)
This graph shows the Thermal Diffusivity values measured on a Linseis LFA 1000 compared to the values measured at AIST* Japan. The literature values of the used Isotropic Graphite from AIST* the measured results on the LFA 1000 vary by less than 2%. *(National Institute of Advanced Industrial Science and Technology, Japan)
The main application field for the LINSEIS L76 Dilatometer series is the CTE measurement of ceramics, brick, tile, porcelain and building materials. Furthermore it is widely used for quality control purposes in ceramics and in metal industries.
Thanks to the fact we started to develop and build Dilatometers in the year 1955,this instrument is very reliable and covers a wide temperature range from RT up to 1000°C, 1400°C and 1600°C with user exchangeable furnaces. It consists of measurement systems made out of quartz glass (up to 1100°C) and Al2O3 (up to 1600°C). The sensor is a highest precision LVDT (linear variable differential transformer), which has an indefinite resolution. Together with the 32 Bit software package LINSEIS WIN-TA / WIN-DIL, the Dilatometer provides an excellent solution for standard quality control type CTE measurements.
The following physical properties can be measured:
CTE, Linear Thermal Expansion, Alpha Physical, Sintering Temperature, Phase Transformations, Softening Points, Decomposition Temperatures, Glass Transition Temperatures
Glass transition and softening point evaluation
Softening point detection with automatic software controlled system shut down
Display of relative/absolute shrinkage or expansion curves
Presentation and calculation of technical / physical expansion coefficient
