<p>A method of operating a tissue processor 20 comprises feeding a reagent from a container 26 into a retort 22 of the tissue processor 20, which retort does not contain any tissue samples. Thereafter, the reagent is returned into the container 26. During feeding, returning and/or in-between a measured value is detected with the aid of a sensor of the tissue processor, which value is representative of the concentration of the reagent. During this feeding, returning and/or in-between no tissue sample is placed in the retort 22.</p> |
