Made of acetal, these disposable plastic cassettes hold tissue specimens during processing and embedding, as well as in storage. Molded from a special high-density polymer, 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. As required they
can be opened or closed and they always relock securely without danger of specimen loss.
