Cassette design is similar to that of the M509 model with a recessed lid, but with four compartments (each 13×13 mm). Made of acetal polymer.

• Small size enables more cassettes to be loaded into labelling machines and storage systems at one time
• Highly resistant to histological solvents
• Flow-through slots (each 1×5 mm) to maximise fluid exchange
• Integrated lid
• Front face inclined 45° to enable use with leading automatic labelling systems

W×D×H: 41×28,5×6 mm
