These disposable plastic cassettes with lids are made of acetal polymer and hold tissue or biopsy specimens during the embedding process and for storage.

They keep specimens safely submerged in liquid and are totally resistant to the chemical action of 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. The lid can be easily snapped apart and locked into the base of the cassette. Lids can be opened and closed as often as necessary and always relock securely without danger of specimen loss. Large labeling areas are located on three sides of the cassette. The anterior writing area is at a 30° angle. The biopsy cassettes feature 1mm square openings.
