US Patent 11635352 Enhanced hydration methods and systems for histology

There is provided a histology system that comprises a microtome configured to expose a face of a tissue block comprising a tissue sample embedded in an embedding material and remove one or more tissue sections from the sample, a hydration system configured to hydrate the tissue block by depositing a hydrating liquid on the face of the tissue block, and a transfer system configured to transfer the one or more tissue sections from the microtome to one or more slides. In some embodiments, the hydration system is configured to produce droplet condensation of the hydrating liquid and deposit the condensation on the face of the tissue block.
