Due to the infection incidence in Berlin and the classification of Berlin as a risk area, only groups from Berlin will be able to measure at BESSY II and HZB CoreLabs at present. For all other user groups, the measurement period from calendar week 45 to 50 has been cancelled.

All external users must provide a negative Corona test certificate (not older than 5 days with respect of the starting time of your activities at HZB - day of testing is day 1) to gain access to HZB.

HZB is providing test capacities for external users on-site. Please find more information on the Corona Test Centre at BESSY II  HERE

According to the current situation our information and REGULATIONS to slow down the spread of the coronavirus are regularly updated.
