The Leica Jung 2030 is low maintenance with a backlash-free micrometer feed system. The pre-lubricated cross roller bearings provide for consistent, accurate sectioning. The coarse-feed positioning hand wheel advances the specimen to the knife edge with a total feed excursion of 25 mm (1″). Because the Biocut 2030 has a counterbalanced cutting hand wheel the sectioning is smooth and fatigue-free. And it has an easily-controllable sectioning speed driven on maintenance-free cross roller guides.
