Typical samples studied in our facility include:

  • tissue pieces
  • cells
  • bacteria
  • viruses
  • macromolecules
  • polymers
  • nanoparticles 

Specimen preparation service

Our laboratory technicians prepare samples for imaging with different EM-techniques. The researcher collects and fixes the samples and brings them to our specimen preparation laboratory for further processing. Instructions on correct way to collect the samples as well as fixative sets are available in the laboratory. We can prepare specimens for both transmission (TEM) and scanning (SEM) electron microscopies. 

EM imaging

We train every user individually to TEM operation and provide technical support during imaging.

SEM imaging is arranged in cooperation with other local units.


We help researchers in all questions related to electron microscopy. We give help in all steps of an EM project from experiment planning to result interpretation.​
