Electron Microscopy Equipment

University of Otago Logo

The following list gives a brief description of the equipment available for use at Microscopy Otago. It is a useful starting point when planning an investigation. For a more detailed discussion of what the equipment can, and can not, do please contact a member of staff.

For more information about what each microscope is capable of, visit our Capabilities webpage. If you are looking for confocal microscopy equipment, you can find more information on the OCCM's website.

You are not permitted to use any of the equipment unless you have been trained to a suitable level and understand any health and safety issues associated with each item. You will not be expected to remember everything after one training session; a staff member will be available to assist you at most times. When you have shown you are competant at using an item of equipment, you will be allowed after-hours access to the facility.

Writing up? This equipment list is useful for finding the name, manufacturer and other specifications when you're writing up a thesis or paper. All company names and addresses are listed as they were at the time of equipment purchase. If you notice something missing which you could have used, please let us know so we can add it.

Zeiss Sigma VP FEG SEM

Zeiss Sigma VP FEG SEM

Zeiss Sigma VP variable-pressure scanning electron microscope (Carl Zeiss Inc, Oberkocken, Germany) fitted with a HKL INCA Premium Synergy Integrated ED/EBSD system (Oxford Instruments, Oxfordshire, UK) and modified Emitech K1250 cryo stage (Emitech, UK).
The Zeiss Sigma is able to perform high resolution imaging with secondary and back scatter electrons (up to 1.7nm at 15 kV and 3.0nm at 1 kV). It is able to operate under variable pressure conditions (from 2 to 133 Pa) and is good for imaging specimens that are poorly conductive or specimens that cannot be imaged under vacuum. The chamber is able to accommodate specimens up to 250mm in diameter and 145mm tall.
