LFA 457 MicroFlash® - Laser Flash Apparatus

State-of-the-art technology for thermophysical properties

LFA 457 MicroFlash® - Laser Flash Apparatus
The LFA 457 MicroFlash® is the most modern product for the determination of the two thermophysical properties, thermal diffusivity and conductivity, in the range from -125°C to 1100°C. Its compact, vacuum-tight construction, automatic sample changer and functional software guarantee the highest effectiveness for challenging materials testing.

The NETZSCH LFA 457 MicroFlash® complies with the latest technology for modern laser flash systems. The table-top instrument allows measurements from -125°C to 1100°C using two different user-exchangeable furnaces.

The innovative infrared sensor technology employed in the system enables measurement of the temperature increase on the back surface of the sample, even at temperatures of -125°C.

The instrument can be used for small and large sample sizes of up to 25.4 mm diameter and, with the integrated sample changer, measurements can be run on several samples at the same time.

The vacuum-tight design enables tests under defined atmospheres.

The vertical arrangement of the sample holder, furnace and detector simplifies sample placement and, at the same time, guarantees an optimum signal-to-noise ratio of the detector signal.

The LFA 457 MicroFlash® is the most up-to-date and versatile LFA system for research and development and for all applications involving characterization of standard and high-performance materials in automobile manufacturing, aeronautics, astronautics and energy technology.
