Leica RM2155 and RM2255 Microtomes

More Information


The Leica RM2255 rotary microtome, designed for fully motorized sectioning of both paraffin- and resin-embedded specimens, offers a broad application spectrum in routine and research laboratories in histology as well as in industrial materials and quality control. Its two-in-one design concept, which allows motorized as well as manual sectioning, provides reproducible quality sections.

The sectioning speed can be adjusted to cut hard materials as well as paraffin-embedded specimens at high throughput without any detriment to sectioning quality. This microtome is designed for users who require a fully motorized/electronic microtome for their laboratory needs.
