This version of the Micromesh™ offers 1676 square openings (0.38mm), allowing for a greatly improved fluid exchange without having to use biopsy pads. Large anterior and posterior slots in both cassette and cover ensure that the Micromesh™ biopsy cassette will sink rapidly. A large square compartment measuring 27mm is perfect even for needle biopsies. The cover does not protrude above the cassette, a great space-saving feature allowing more cassettes to be stacked in automatic labeling machines and tissue processors.
