Electron Microscopy

Introduction

The Electron Microscopy (EM) Facility is in the basement of Botterell Hall on level B2.  This facility has one transmission electron microscope (TEM), a Hitachi H-7000 (TEM) as well as a Hitachi S-2300 scanning electron microscope (SEM).  Other equipment in this facility includes an RMC ultramicrotome, gold and carbon sputter coater, professional negative film scanner, and darkroom.  A dedicated technician, Dr. Xiaohu Yan, oversees the daily operation of the facility and maintains the operational usage of all the equipment.  The primary source of funding for this facility is through pay-for-service fees.

Full Service Microscopy

To determine whether ultrastructural data collection by TEM and/or SEM is applicable to your research, we offer a cost-effective pilot study.  We will prepare samples of your material for you at a reasonable cost. If you determine that ultrastructural data collection is suitable for your research, we can provide the full service and/or provide the necessary training on sample preparation / equipment usage.
