The JEOL 1210 is a conventional transmission electron microscope which is optimized for high contrast imaging at low to moderate magnifications (<100,000X). This instrument is most commonly used to image thin (<200nm) samples of polymers and frozen hydrated solutions (surfactants, colloids, emulsions). This microscope is also used to train users new to TEM. It has a maximum operating voltage of 120 kV. It is capable of Imaging in high-magnification (>1,000X) and low magnification and diffraction modes. It has a minimum dose software, free lens control, and some on-line measurement capabilities.
