Abstract: The invention relates to a method for embedding a tissue sample into an embedding medium. In a first step the tissue sample is held in an intended orientation in a container by means of a holding element that presses the tissue sample against a base of the container. In a further step a liquid embedding medium that has a temperature above 64 degrees Celsius, in particular in the range from 65 degrees Celsius to 67 degrees Celsius, or a temperature of 66 degrees Celsius, is poured into the container, and the base of the container is cooled.

Abstract: A method (100) for fixing at least one tissue sample (1) is carried out using a tissue processor (10). The tissue sample (1) is introduced at a first temperature level and a first pressure level into a fixing reagent (2) containing at least one nitrogen-containing compound capable of pressure- and/or temperature-dependent release of at least one aldehyde. The tissue sample (1) is left in the fixing reagent (2) for a fixing time period during which the fixing reagent (2) is brought to a second temperature level above the first temperature level and/or to a second pressure level above the first pressure level. A concentration in the fixing reagent (2) of the nitrogen-containing compound is ascertained using at least one concentration measuring device (14) of the tissue processor (10), and a signal is outputted on the basis of a measured value of the at least one concentration measuring device (14).
