The project is based on the agreement between Contur and Karolinska Institutet, Uppsala University and Umeå University signed in December 2009. The ConturELN system may be used by all scientists at the three universities, in total over 5 500 scientists.Currently some groups are using ConturELN at Karolinska Institutet, and they are all offered to migrate their records into the central system. The electronic laboratory notebook will be made available to all research groups and the aim is to include up to 1500 users by the end of 2011.
