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: A tissue infiltration apparatus, system and method are described, allowing accelerating infiltration of the tissue sample with a variety of reagents fluids. The apparatus comprises a reaction chamber adapted to receive a tissue sample and a dielectric fluid to be infiltrated into a tissue sample. The reaction chamber comprises a bottom and a circumferential wall with a window section that is transparent for microwave irradiation. A holding element holds the tissue sample over a predetermined time period at a distance of 3PD of the dielectric fluid from the window section is provided. PD is the penetration depth of the microwaves into the dielectric fluid and defined as the depth where the initial microwave field intensity has been reduced to 1/e. A microwave system irradiates microwave irradiation through the window section into the reaction chamber.

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.

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.
