Leica Microsystems - RM2255
Fully Automated Rotary Microtome
Designed for fully motorized sectioning of both paraffin- and resin-embedded specimens, the Leica RM2255 supports a broad spectrum of applications; in routine and research laboratories; in histology; in industrial materials and quality control.
Its two-in-one design concept, which allows motorized and manual sectioning, provides reproducible high-quality sections.

Features of RM2255
Consistent sectioning speed Consistent sectioning speed and force of the fully-automated cutting motor supports consistent, high-quality sectioning and helps to reduce musculoskeletal disorders caused by repetitive motion.
Precision orientation system The optional 8° X/Y precision orientation system with calibrated controls helps to quickly orient already cut specimens (re-cuts). The system then rapidly returns the exact zero position, which is marked by two red indicators.
Large 70mm vertical stroke The large 70mm vertical stroke allows sectioning of super mega cassettes and also supports safer specimen changing due to the greater distance to the knife edge.
Unencumbered work area Fewer clamping levers provide an unencumbered work area.
