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.
