tissue with eosin (erythrosine) at the grossing bench and cut two levels at
40 microns."

Do NOT use eosin for this purpose. It's highly fluorescent, and will
interfere with any method (such as FISH) that relies on fluorescence.

Safranin O works well for this purpose - placing the specimens on those
blue pads after marking them. It's easily available - this is the red
component of the Gram stain done by any microbiology service.
