Acetal poymer. Disposable plastic cassettes hold tissue specimens during the embedding process, as well as in storage.

• Totally resistant to the chemical action of histological solvents
• The one-piece integral lid eliminates the need for separate steel lids
• Available in several colours

Moulded from a special high density polymer, these patented cassettes keep specimens safely submerged in liquid. The efficient flow-through slots maximise fluid exchange and ensure proper drainage. They can be opened and closed as often as necessary and will always relock securely without danger of specimen loss. Large labelling areas are located on three sides of the cassettes for more convenience. The anterior writing area is slanted at a 45° angle to make the cassette more suitable for use with certain types of cassette-labelling instruments.
