There is currently an open call by the JRC for access (till beginning of May)  to their lab facilities via the open-lab initiative and you are all eligible to submit proposals to have access (typically 1-2 weeks as a single block or split).  Although there is a nominal fee for instrument use (around 50euro/day/instrument) these costs are eligible for reimbursement from EU H2020 projects.

If this is of interest, general information and the list of instrumental facilities can be found at the link below.
