Environmental Scanning Electron Microscope (ESEM)

Field-Emission Environmental Scanning Electron Microscope (ESEM-FEG) with Energy-Dispersive Spectroscopy (EDS)

A versatile microscope with 2 nm ultimate resolution. Works well in both Hi-Vac mode (normal SEM) and Wet mode (as an ESEM). In Wet mode, the Peltier stage may be utilized to keep samples at 100% R.H. while they are being imaged.

For additional information about this piece of equipment, see the Calendars, Contacts, and Fees pages.
