Environmental Scanning-electron Microscope (eSEM-FEI Quanta 250)

Environmental Scanning-electron photograph

ESEM provides access to studies of wet biological samples, nano-bio composites and nano-fluidic phenomena. Studies of real-time redox chemistry involving nano-objects and the imaging of fluids under microfluidic conditions are some of the topics, in which the ESEM is playing a key role.
