The description describes a tissue processor (10) for processing tissue samples for histological analysis. The processor comprises two retorts (12, 14), baths (16-22), reagent containers (26), a pump (44), and valve. The valve distrubutes the reagent from one container to either retort. Separate reagent lines connect the wax baths to the retorts (the subject of one claim). A method is described (and claimed), of infiltrating a sample containin a reagent such as a dehydrating agent like an alcohol, where the infiltrating material is heated to a temperature at or above the boiling point of the reagent, to boil off the reagent when the tissue sample is contacted by the infiltrating material. Another claim defines the pressure in the retors as being reduced to lower the boiling point of the reagent. |
