The Tissue-Tek® III Uni-Cassette® System is designed to provide specimen identification and security from the grossing bench to the paraffin block. 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. Has virtually unlimited applications, including identifying surgical specimens from autopsies, STAT biopsies and frozen sections. The cassettes come with an attached lid. Available in 12 colours.
