Abstract: The invention relates to a method and device for the cross-referencing of identification (1) of tissue slice supports (2), for microtomised analytical samples still to be mounted thereon, with identification information (3) of a tissue sample holder (4) of a tissue sample (5) which is not yet microtomised. The conventional problem of cross-referencing is improved in a simple manner, whereby the identification information (3) for the tissue sample holder (4) is automatically detected when positioned in the microtome (6) and an identification (1) corresponding thereto is automatically transferred to at least one tissue slice support (2) and that tissue slice support (2), provided with the identification (1), is dispensed for application of the tissue sample slice at the moment when a tissue sample slice must be applied to a tissue slice support (2).
