  • Patent number: 8609042
    Abstract: A method of cutting at least one thin section from a sample block that is arranged in a cassette and tagging at least one specimen slide such that it can be allocated to the specific sample block from which the thin section has been cut. The method includes removing a cassette from a cassette magazine; reading the machine-readable coded information of the cassette identifier; generating by at least one tagging unit a specimen slide identifier that interrelates to the cassette identifier read by the reading unit; inserting the cassette into a microtome; transferring data from the microtome to a tagging unit via a data transfer path while the cassette is inserted into the microtome; enabling tagging of the specimen slide; tagging the specimen slide by the tagging unit; and cutting the thin section and transferring it onto the specimen slide that was tagged by the tagging unit.

  • Patent number: 8383418
    Abstract: A method for operating a tissue processor is described. During the operation of a tissue processor a reagent is fed from a container into a retort of the tissue processor, which retort does not contain any tissue samples. Thereafter, the reagent is returned into the container. During feeding, returning and/or in between feeding and returning a measured value is detected by a sensor of the tissue processor. This value is representative of a concentration of the reagent. During this feeding, this returning and/or in between no tissue sample is placed in the retort.
