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. In a further step a separating motion is executed by way of which the tissue sample and the holding element move away from each other, those layers of the embedding medium through which the holding element moves during the separating motion having, during the separating motion, temperatures in the range from 54 degrees Celsius to 64 degrees Celsius, in particular of 60 degrees Celsius, and/or those portions of the embedding medium which are directly adjacent to the holding element having, during the separating motion, a temperature in the range from 54 degrees Celsius to 64 degrees Celsius, in particular of 60 degrees Celsius.

Method and automatic machine for embedding a tissue sample into an embedding medium

An apparatus for holding a tissue sample including a retaining member having a first tissue engaging surface and at least one biasing element, the first tissue engaging surface being moveably attached to the retaining member by said biasing element; and a base having a second tissue engaging surface and configured to engage the retaining member to form an interior area with the first and second tissue engaging surfaces facing each other, wherein the at least one biasing element urges the first tissue engaging surface toward the second tissue engaging surface to retain the tissue sample therebetween in the interior area.

Tissue cassette with biasing element

The invention relates to an apparatus for treatment of histological samples. The apparatus includes at least a working station, in which the sample gets into contact with a liquid reagent. Further, the apparatus includes a purification device, which blows off at least a part of the reagent adhering to the sample and/or the sample holding arrangement by means of a gas flow, or which sucks off at least a part of the reagent adhering to the sample and/or a sample holding arrangement.

Apparatus for working on histological samples

A method for treating a tissue sample including placing at least one tissue sample on an cassette which has: a retaining member, a base and at least one biasing element; placing the at least one tissue sample in the tissue cassette; attaching the base and the retaining member to retain the tissue sample; processing the tissue sample in the tissue cassette with one or more solvents; and embedding the tissue sample in a paraffin to form an portion of paraffin in which the tissue sample is embedded in the tissue cassette, wherein the embedding comprises adding molten paraffin to the interior area of the tissue cassette and allowing the paraffin to become solid.
