The Tissue-Tek® III Biopsy Uni-Cassette® System is designed to provide specimen identification and security from the grossing bench to the paraffin block and is suitable for biopsies, thanks to its fine pores (1 mm2). Each cassette system is optimised for maximum fluid exchange during the processing cycle. When utilised with appropriately sized Base Molds, the cassette becomes the supporting structure of the paraffin block during embedding. The cassettes come with an attached lid. Available in eight colours.
