The Zeiss EVO 60 is an environmental scanning electron microscope (EP-SEM). In addition to the standard high vacuum (HV) operating mode, the EVO 60 is capable of operating in extended pressure mode (EP). While operating in extended pressure the EVO 60 is capable of viewing specimens that have not undergone the traditional drying and coating preparations.

Using small quantities of filtered air and water, the EVO 60 creates a non-destructive coating across the sample preventing charge from building. The EVO 60 also comes equipped with a removable hot/cold stage. When used in combination with the EP mode, the hot/cold stage allows for wet samples to be viewed under the electron beam. Accompanying the EVO 60 are a back scatter detector, energy dispersive x-ray spectrographic detector, and electron back scattered diffraction detector.
