Histological cassettes are used in the laboratory to place clinical tissue samples (for example, biopsy samples) in them in order to allow their processing (fixation, embedding in paraffin, dehydration, infiltration) in preparation for subsequent cytological or histological examination and storage. They are plastic containers with a tear-off lid, drainage holes designed to maximize the effect of liquid on the contents during the immersion of the tissue in the main device into which the container is loaded. Can be used in automatic posting machines.
