Scanning Electron Microscopy (SEM) laboratory

The Scanning Electron Microscopy (SEM) research laboratory is home to two scanning electron microscopes as well as sample preparation equipment. The lab is connected to the Light Microscopy laboratory which boasts research microscopes (stereo, compound, fluorescence, phase contrast, and polarizing) with digital cameras and software.

The facility provides services to honours and postgraduate students, research staff, research fellows, general staff, and commercial projects and consultancies.

Both electron microscopes are used for the investigation of biological and non-biological materials. The systems are equipped with SE (secondary) and BSE (backscatter detectors), X-Ray Analysis capabilities (EDS) and element distribution mapping. The Zeiss EVOLS-15 is also is fitted with VP and EP detectors, and a cold-stage and automated imaging using Zeiss Smart SEM AII (Automated Intelligent Imaging). The Hitachi TM4000 is fitted with High Sensitivity Low Vacuum SE Detector (UVD), cold stage and STEM.

Training, booking and fees

The courses listed here are available to honours, postgraduate students, staff members (academic and professional), and commercial research/consultancy groups. For all training courses, bookings and enquiries, please contact Maxine Dawes.

Light Microscopy

All Light Microscope courses are offered on an individual needs basis, depending on type of work and microscope required.

Introduction to the SEM

This course covers Basic and Advanced SEM techniques as well as techniques in sample preparation and are povided for either the Zeiss EVO- LS15 or Hitachi TM4000 Desktop SEM.

Introduction to X-ray Analysis

This course covers X-ray Analysis using Energy Dispersive Analysis (EDS). Please note: A pre-requisite for this course is the Introduction to the SEM course.

All new users will be trained on the SEM on a one-to-one basis unless a group course is being held.
