Leica RM2245 Microtome

The Leica RM2245 microtome is a semi-motorized rotary microtome, designed for routine and research applications in histopathology and industrial quality assurance laboratories. The Leica RM2245 microtome has been specially designed for the experienced user who prefers manual over motorized sectioning.

Manual sectioning is enhanced by a high-precision motorized specimen feed, which results in efficient operation with maximum section quality and reproducibility.

The RM2245 microtome allows the sectioning of samples in two manual sectioning modes: rocking mode (where the handwheel is turned back and forth over a short distance) and conventional manual sectioning with full-handwheel rotation.

All important controls are located on a user-friendly separate control panel with adjustable inclination angle for ergonomic operation. Specimen retraction (Retract) handwheel/specimen head locking function (Lock), trimming thickness, section thickness as well as section and section thickness totalizer are indicated directly on the instrument.
