Fortessa Trainings

Content of the Basic Fortessa Introduction Course

  • Principle & construction of a flow cytometer
  • Startup operations, operation and shutdown procedures
  • Replacement of sheath and waste canisters
  • Sample preparation
  • Sample measurement
  • Sample handling and disposal of GMOs according to the “Gentechnikgesetz (GenTG)”
  • Spectral overlap compensation
  • Operating FACSDiva software
  • Troubleshooting
  • Operating booking system and input screen (for billing)
  • Optional: More detailed information about FACSDiva & flow cytometry

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:

  • 13.08.2024
  • 14.08.2024
  • 29.08.2024
  • 10.09.2024
  • 10.10.2024
  • 11.10.2024
  • 24.10.2024
  • 05.11.2024
  • 20.11.2024
  • 05.12.2024

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".

Overview of MIAP Partner Units

Please note:

Our user fees cover only a small fraction of our total running costs, most of which in fact are covered by our home institutes (Klinik für Innere Medizin I, Centrum für Chronische Immundefizienz (CCI), Tumorzentrum Freiburg/DKTK and the Medical Faculty. The majority of our machines were financed with the help of outside sources such as the DFG, Land Baden-Württemberg, or BMBF. We therefore depend on proper acknowledgement and listing of the project numbers below.

Lighthouse Core Facility is funded in part by the Medical Faculty, University of Freiburg (Project Numbers 2023/A2-Fol; 2021/B3-Fol), the DKTK, and the DFG (Project Number 450392965).

 Publications, posters or presentations that make use of services or data collected at the facility or by its staff should list these contributions/project numbers accordingly. Thank you.
