These cassettes are identical to Series M490 but the anterior writing area has a 45° instead of a 30° angle. The more acute angle makes these cassettes more suitable to be used with some models of cassette labelling instruments. These disposable cassettes hold tissue specimens very efficiently during the embedding process, as well as in a storage file. Molded from acetal, these cassettes keep specimens safely submerged in liquid and are resistant to the chemical action of most histological solvents. The efficient flow-through slots maximize fluid exchange and ensure proper drainage. The one-piece integral lid eliminates the need for separate steel lids. Just snap it apart and conveniently lock the lid into the base of the cassette.
