Wildfire In situ TEM Heating

Wildfire is a revolutionary nano-chip solution that enables direct in situ TEM and EDS studies of materials at the highest temperatures. The optimized MEMS based chip provides the most stable and widest range of temperatures without compromising microscope performance.

With versatile window designs for studying FIB lamella, thin films, or particulate specimens, an exciting range of applications becomes accessible.

Why Wildfire?

  • Highest temperature range – accurately and repeatably heat up to 1300°C with minimal drift rates
  • Simplified sample preparation – every chip has multiple window shapes for supporting lamellae, thin film, and particles
  • High impact results – minimized bulging, drift, and infrared emission ensures high quality images and spectra can be acquired

Versatile window designs optimized for multiple types of samples – particles, thin films, or FIB lamellae.

Reduced IR emission: create EDS maps up to 1000°C.

Wildfire Nano-Chip

The revolutionary Wildfire nanochip has been redesigned to make every aspect of your in situ TEM workflow streamlined – from sample preparation to imaging and EDS data collection.

  • Sample preparation made easy
    Circular and elongated window designs on every chip provide maximum versatility in sample preparation. With minimal topography around window edges, capillary effects are minimized during drop and thin film transfer becomes easy. Elongated windows are ideal for maximizing visibility at high tilt angles.
  • Reliable and homogeneous temperature
    Optimized temperature homogeneity (≥99.5%) and temperature accuracy (≥95%) over the largest viewable area (850 µm2).
  • Extremely stable
    The Nano-Chip demonstrates negligible membrane bulging up to 1000°C and <7 µm bulging at 1300°C. Keep your region of interest in the field of view during temperature ramping with drift rates <0.3 nm/min at 1000°C.
