Fortessa Trainings

Since June 2020 we offer the newly designed training courses for the FACS Fortessas and the flow cytometry basics..
The regulations for keeping the minimum distance make it impossible to keep the previous training form. Therefore, we were switching to largely contact-free online training.
If you would like to use our Fortessa flow cytometers (or the Canto II) and have not yet received instruction on these instruments from us, please send us an email to facslab(ät)uniklinik-freiburg.de. You will then receive an email from us with all details and information.
Among them are:
- several links to instructional videos (total running time about 3hrs)
- an on-site appointment for questions and the short written test
You will then have about 1 week time to watch the videos and fill out forms if necessary.
At an individual on-site appointment for a maximum of 2 persons each (duration in total maximum 90 min.), the formalities are then completed (including a 10-minute written test) and, if possible, permission to use the equipment is granted.
The next dates for the on-site appointments and final exams are planned for:
- 17.12.2024
- 08.01.2025
- 23.01.2025
- 07.02.2025
- 18.02.2025
- 05.03.2025
- 20.03.2025
- 04.04.2025
- 15.04.2025
- 30.04.2025
- 14.05.2025

Online Booking System
Our booking system for our equipment: All booking calendars are accessible via the internet from outside the Uniklinik intranet.
Apply in time and register now at http://booking.core-facility.de. So that you can continue to use our devices and our service.
Sorter Booking Online
For the cell sorters, you can use the new calendar to look online at current bookings to find an available sorting slot, and you can even request a specific sort time by provisionally reserving a sort appointment in advance. If the requested appointment is accepted, you will receive a written confirmation of the desired appointment. Only then is your sort appointment considered "officially" to be scheduled.
Our new calendar system can be easily accessed, even from outside the Uniklinik network via the Internet. However, to access the system you first have to register as a user in it. For users with an Uniklinik LDAP login the registration process is very straightforward. Using your LDAP login and the corresponding password you can log in. This will automatically send us a request to activate your account. Once your user account has been activated, you will receive a one-time confirmation email from us. After that, you can then use the system.
External users (Vorklinik, University) can also access the system. To do so, please visit http://booking.core-facility.de and click "First Time User? Register".
The address of the new Lighthouse booking system can be found at the following link: https://ztz-buchung.uniklinik-freiburg.de/Web/index.php (or just http://booking.core-facility.de)
Recognized core facility of the Medical Faculty
Lighthouse is a recognized Core Facility of the Medical Faculty of the University of Freiburg.
RIsources
Lighthouse is part of the RIsources Database of the DFG.
The RIsources listing simplifies applying for funding for the use of Lighthouse services within DFG grant applications.
Cytometry.de
We are also a part of cytometry.de, a national network of cytometrists and cytometry core facilities of the DGfZ / Deutsche Gesellschaft für Zytometrie.
MIAP
Lighthouse is a member unit of the Microscopy and Image Analysis Platform (MIAP), a tri-national network of microscopy and image analysis facilities from throughout the region, including Freiburg, Basel, Strasbourg and the surrounding area.
Our user fees cover only a small fraction of our total running costs. In fact, most of the running costs are covered by our home institutes (Department of Medicine I, Center for Chronic Immunodeficiency, DKTK/Comprehensive Cancer Center Freiburg) and the Medical Faculty,- University of Freiburg, while the majority of our machines were financed with the assistance of public funding sources such as the DFG, Land Baden-Württemberg, or BMBF. We therefore depend on proper acknowledgements in publications and grants and proper listing of the project numbers below.
Specific Project Numbers
Our general support project number from the Medical Faculty (2023/B3-Fol) should always be listed, along with the specific instrument or service area project number(s) as listed below:
