Abstract: A method for controlling a tissue processor and a tissue processor for processing tissue samples is described. A retort is provided including a cover that can be opened and closed by an operator. The retort cover is closed prior to tissue processing. The actuation state of a first and a second operating element can be determined. An operator is prompted to confirm unlocking of the closed retort cover by actuating a second operating element. The tissue processing is interrupted when an actuation of the second operating element is determined and the closed retort cover is unlocked and is continued after the retort cover is once again locked. After having completed tissue processing the retort cover is unlocked. By means of the described method and tissue processor improper intervention during ongoing tissue processing is prevented.

Abstract: In the automatic processing of tissue samples in a tissue processor, the tissue samples are placed in a retort of the tissue processor. The tissue samples are exposed to a fixation reagent (FIX) in the retort. Afterwards, the tissue samples are exposed to a dehydrating reagent (ALK). Thereafter, the retort is cleared with an intermedium (INT) for removing the dehydrating reagent (ALK). Finally, the tissue samples are treated with a carrier material (CAR). Between the clearing of the retort with the intermedium (INT) and the treatment of the tissue samples with the carrier material (CAR), the retort is cleared with a carrier material protecting reagent (CARPRO) in which the intermedium (INT) and the carrier material (CAR) can be mixed.
