A 300 KV Transmission Electron Microscope equipped with Field Emission Gun and Cryo-Stage  

This microscope is capable of operating with specimens held at the temperature of liquid nitrogen (-196 C). At these low temperatures biological materials are that is preserved in a living state (vitrified) and retain their three dimensional properties.  The microscope can accelerate electrons at voltages up to 300,000 EV producing a very coherent and short wavelength illumination system.  Images of frozen specimens are collected on photographic film and represent three dimensional projections of two dimensional objects. Three dimensional images are produced by computer based image analysis.
