The JEOL JEM 2100 LaB6 TEM is a workhorse microscope for multi-purpose use. This transmission electron microscope provides solutions for a wide range of problems in many fields of science and engineering, including nanomaterials, nanoscience, biological sciences, and medical sciences.

The JEM-2100 TEM has three independent condenser lenses and produces the highest probe current for any given probe size. It also allows the user to select various illumination conditions, ranging from full convergent beam to parallel illumination. These functions enable improved analytical and diffraction capabilities in addition to high resolution imaging.

The JEM 2100 is also equipped with a scanning image observation device, thus becoming a so-called scanning transmission electron microscope (STEM). This enables researchers to observe and investigate samples in a scanning mode that further expands its applications; for instance, to acquire a material’s chemical composition from a small point or a line profile, or to reveal elemental distribution maps.

The JEM 2100 has been used for microstructure studies of a variety of materials, including biological and soft materials. With special specimen holders and TV and CCD cameras, it is also capable of carrying out high temperature and liquid nitrogen temperature in-situ studies for dynamic observation and experiments.
