Acetal polymer. Cassette design is similar to that of the M509 model but specially designed to hold biopsy specimens.

• Small size enables more cassettes to be loaded into labelling machines and storage systems at one time
• Disposable plastic cassettes are highly resistant to histological solutions
• Small, square openings for good fluid exchange
• Integral, recessed lid
• Front face inclined 45° to enable use with certain automatic labelling systems
