Electron Microscopy

Transmission and Scanning Electron Microscopes and Sample Preparation

Equipped with several Transmission (TEM) and Scanning (SEM) Electron Microscopes as well as related sample preparation equipment for the use of the UMass community as well as external customers. The Center serves both materials and life-sciences communities and most of the instruments options are focused on analytical capabilities such as Energy Dispersive X-Ray Spectroscopy (EDS) and Electron Energy Loss Spectroscopy (EELS).

Cressington 108 Sputter Coater

Cressington 108 Sputter Coater

Cressington 108 Sputter Coaters are ideal for routine sample preparation. Compact, economical and simple to operate, they offer rapid pumpdown times, fine-grain coatings and negligible sample heating.

Cressington 208 Sputter Coater

Cressington 208 Sputter Coater

The Cressington 208HR High Resolution Sputter Coaters offer real solutions to the problems encountered when coating difficult samples for FESEM imaging. FESEM applications need extreme- ly thin, fine grain, uniform coatings to eliminate charg- ing and to improve contrast on low density materials.
