Key Features
Measurements Up to 1250°C: The LFA 717 HyperFlash® HT is an advanced thermal analysis instrument utilizing the latest xenon flash lamp technology to enable measurements at temperatures reaching 1250°C. This innovative system eliminates the need for laser classification, ensuring both ease of use and compliance with safety regulations.
Broad Sample Compatibility: The LFA 717 HyperFlash® accommodates a wide array of sample materials, supporting both round and square shapes.
Vacuum-Tight Furnace for Controlled Atmospheres: Its vacuum-tight furnace is designed to create controlled atmospheres, effectively preventing oxidation during heating processes. This furnace includes an internal pump that automatically evacuates the chamber before each measurement, maintaining a defined atmosphere for accurate results. Additionally, it offers extra ports for external pumping equipment, enhancing operational flexibility.
Time-Saving Mini-Tube Furnaces: Equipped with four alumina mini-tube furnaces, the system supports rapid heating rates of up to 50 K/min, delivering exceptional sample throughput and unmatched test speed across the temperature range. Each of the four sample positions features its own thermocouple, ensuring fast stabilization times. Capable of measuring ten temperature steps from room temperature (RT) to 1250°C in just one hour, these furnaces are built for efficiency and precision, making them ideal for demanding laboratory and research applications.
Advanced Corrections for Challenging Samples: The latest iteration of our analysis software incorporates an improved analysis pulse correction feature. This enhancement is crucial for high-precision applications where exceptional time resolution is critical, particularly beneficial when analyzing thin or highly conductive samples, or when the light pulse’s duration overlaps with the sample’s thermal response.
The LFA 717 HyperFlash® HT is an indispensable tool for researchers and industries requiring precise thermal property measurements, solidifying its role as an invaluable asset in the field of materials science.
