LVEM25 Installed at the FDA - National Center for Toxicological Research (NCTR)

The FDA - National Center for Toxicological Research (NCTR) has selected the LVEM25 Low Voltage electron microscope to add to its research instrumentation. This is the first installation of this new microscope in the USA.

The U.S. Food and Drug Administration's National Center for Toxicological Research (NCTR) is a global resource for collaboration providing consultation, training, and innovative scientific solutions in support of FDA's mission to improve public health.

The LVEM25 is the next generation of low voltage electron microscopes, built on the revolutionary technology platform of the LVEM5 that combines advanced imaging with unparalleled benchtop convenience. Final image resolution is more than twice better on the LVEM25 as compared to an LVEM5 equipped with TEM-BOOST

The LVEM25 is our top of the line offering and is the only low voltage transmission electron microscope designed to operate at 25kV. This is well below typical accelerating voltage of traditional EM (80-200kV), resulting in increased electron scattering which in turn leads to greater contrast in the TEM image.

The LVEM25 is able to work with conventionally prepared thin sectioned materials at approximately 200nm thicknesses.

Benefits of improved contrast

  • Improved contrast - Lower threshold for density differences
  • Visualize samples that cannot be resolved by high kV methods without the use of heavy metal stains
  • Avoid artifacts : non-existing structures brought about by stains
