Suitable for hoppers accepting plastic sleeves, these biopsy cassettes will load in cassette labeling instruments in one simple operation. Just load the 75-cassette QuickLoad sleeve in the hopper and you are ready for printing. Similar to the design of the M507 model, it incorporates a unique recessed cover, a great space saving feature allowing more cassettes to be stacked in automatic labeling machines and in storage cabinets. Molded from acetal, these cassettes keep specimens safely submerged in liquid and are resistant to the chemical action of most histological solvents. The SLIMSETTE ensures efficient fluid exchange and drainage thanks to 114 openings each measuring 1 x 5 mm. The anterior writing area is slanted at a 45 angle.
