Equipment Description

The Georgia Tech Hitachi S-3700N Variable Pressure SEM, located in the Georgia Tech Biocleanroom, features a low vacuum observation of 6–270 Pa (7mT-2Torr) which enables imaging of non-conductive samples (dielectrics) and wet/moist samples such as cultured cells, without traditional sample preparation (gold coating/drying). A Deben Coolstage controls sample temperature between -10F and 120F to control sample vapor pressure.
