LFA 1000 Laser Flash Apparatus (Thermal Conductivity / Diffusivity)

LFA 1000 Laser Flash Apparatus (Thermal Conductivity / Diffusivity)

000

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.

Materials

Ceramic/Glass/Building Materials, Metals/Alloys, Inorganics

Industries

Ceramics, Building Materials and Glass Industry, Automotive / Aviation / Aerospace, Power Generation / Energy, Research, Development and Academia, Metals / Alloys Industry, Electronics Industry

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.

Pyroceram 9606

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)
