Description:
The CRYO ARM™ 300 (JEM‑Z300FSC) is a field emission cryo‑electron microscope designed for observation of bio‑molecules at cryogenic temperatures. The instrument is equipped with a cold field emission gun providing a high‑brightness electron beam with very small energy spread, offering high coherency and resolution. An in‑column Omega energy filter enables acquisition of energy‑filtered images and energy‑loss spectra, with zero‑loss images providing high contrast by reducing chromatic aberration. The automated specimen exchange system stores up to 12 samples and allows exchange of arbitrary samples while keeping others cooled. The system incorporates a Hole‑free phase plate for enhanced contrast in biological specimens. Automated image‑acquisition software enables efficient Single Particle Analysis imaging with automatic hole detection on specimen grids. Auto adjustment functions including auto focus, auto coma‑free alignment, and auto parallel‑beam illumination are available as optional units.
