Our mission

Our microscopy facility, integral part of the Faculty of Life Sciences, comprises advanced video, light and electron microscopy combined with atomic element analysis, as well as means for documentation of biological topics by photography and scientific videography.



We elucidate structures of various degrees of complexity which will thereby contribute to a better understanding of function, ontogenetic and physiologic processes, as well as phylogenetic relationships. This includes widespread cooperation with other research institutions in Austria and abroad.


We teach and train students in light-and electron microscopic techniques and we supervise Bachelor and Master Students with a sound interest in structural/ functional relationship.

Assistance/ Support

We assist our customers with technical equipment and expert guidance in order for them to obtain the maximum benefit to execute their research projects. Besides of members of faculty and the university, we welcome customers from other educational and research institutions and from the industry.



When using our equipment, please insert this text in the acknowledgement of your publications:

“Microscopy (to be specified if necessary) was performed at the Core Facility Cell Imaging and Ultrastructure Research, University of Vienna - member of the Vienna Life-Science Instruments (VLSI).”


New Transmission Electron Microscope available

The ZEISS EM 900N is an electronically refurbished revision of the popular EM 109 and then as now in use in numerous EM-Labs. It offers an intuitive handling, generates high contrasted images ideal for tissue sections and operates with the same camera and easy to use imaging software (ImageSP) as our ZEISS Libra 120. 

New Labs are fully operational

After performing some necessary modifications all our lab rooms and microscopes are prepared and ready for use. As the new booking platform STRATOCORE is not yet implemented, temporarily please contact siegfried.reipert@univie.ac.at for booking any rooms or devices.

In Memoriam Emer. o. Univ.-Prof. Dr. Walter G. Url

Das Team von CIUS betrauert den Tod von emer. o. Prof. Dr. Walter G. Url, der am 10. April 2021 in seinem 92.  Lebensjahr verstorben ist. Er war ein inspirierender Lehrer, der sich Zeit seines Lebens für die Erhaltung von Natur und Umwelt eingesetzt hat. In unvergesslichen Exkursionen, Praktika, Vorlesungen und Vorträgen gab er sein Wissen an Generationen von Studierenden der Biologie, Pharmazie und
Ernährungswissenschaften weiter. 

Seine außergewöhnliche Persönlichkeit, die Exkursionen mit ihm, seine Vorträge und Filme  haben uns motiviert und werden uns stets in Erinnerung bleiben.

Unser Mitgefühl gilt seiner Tochter Elisabeth und ihrer Familie.

Lattice organs and newly characterized submarginal pore-plates and pore-fields of the carapace in Ascothoracida (Crustacea: Thecostraca)

Grygier M.J., Klepal W. (2020)

The ultrastructure of the animal cuticle has attracted the interest of scientists for decades. Especially the sensory cuticular structures like setae and pores, either singly or arranged in clusters, are a valuable taxonomic character. We focused on cuticular organs of Ascothoracida.

Retirement of Prof. Dr. Irene Lichtscheidl

Prof. Dr. Irene Lichtscheidl has reached the end of her active position as Head of the Core Facility of Cell Imaging and Ultrastructure Research.

She looks back on a productive and fruitful research career on plant cell biology under extreme conditions that she pursues with an admirable endurance, including worldwide projects on heavy metal contamination, soil remediation and carnivorous plants.

We appreciate her creative pleasure in sharing her knowledge to colleagues and students.

Thank you, Irene!
The CIUS-Team

Grant awarded to Sabine Dürr

Sabine Dürr received a grant from the Hochschul-Jubiläumsfonds in the amount of 3300 € for ''Was macht das Fettkraut fett? - Korrelative Mikroskopie der Drüsenzellen von karnivoren Pflanzen"

This project comprises analyses of structure and function of the enzymatic glandular cells and in parallel a development of innovative microscopy protocols for plant cell research.

Congratulation Sabine!

New TEM Software for ZEISS Libra 120

The ImageSP Software is a user-friendly application designed specifically for the post column camera Sharp:eye TRS (2 × 2 k). Beside a straight forward handling, the CCD - read out is considerably faster than with the previous software. It provides a fast live view, panorama function for beam shift and unlimited sample shift, faster and clearer spectroscopic image acquisition and processing.
A free desktop version of the software is available for measurements or post-processing.
