Electron microscopy uses a beam of accelerated electrons to visualise specimens. This can create high resolution images that reveal the fine structures of cells, microorganisms, molecules, metals, crystals and many other specimens.

Your project
Richard Easingwood
To start a project, please contact a staff member to discuss options, normally this contact will be Richard Easingwood. If appropriate, we will then ask you to register your intention to use the facility so that we have your details.
If you are new to electron microscopy, discussing your plans before you start collecting specimens, especially biological specimens, is strongly advised. The staff will help you with specimen preparation and, where appropriate, train you to use the equipment.
Depending on your needs and the scale of your project, you may choose to use the facility in a fairly independent manner (subject to appropriate training and staff approval), or have the staff do the bulk of your work.

Registration
To begin a new project please read the User Policy and complete a Project Registration form. This includes projects involving transmission electron microscopy (TEM), scanning electron microscopy (SEM), ultramicrotomy sectioning, specimen preparation, or supply of liquid nitrogen.
Those paying with a University of Otago account code should complete the registration for internal users. Everyone else should complete the form for external users. External users usually include those from other universities and everyone using an external purchase order. Regular external users can be set up with a University Receivable Account for ease of future billing - please request an account application if you would like to pay this way.
