Leica Biosystems RM2245 Semi-Automated Rotary Microtome
The RM2245 is a semi-motorized rotary microtome, designed for routine in histopathology.
Manual sectioning is enhanced by a high-precision motorized specimen feed, which results in efficient operation with maximum section quality and reproducibility.
Choose between conventional, full-hand-wheel rotation, manual sectioning or "rocking mode", where the hand-wheel is turned back and forth over a short distance. The instrument has been specially designed for the experienced user who prefers manual over motorized sectioning and meets the many requirements of modern laboratories.
Safety during sectioning
User safety is ensured by the integrated, red finger protection guard of the knife holder E that uniquely shields the blade edge. When used correctly the integrated finger protection guard rules out potential injuries.
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.
Smooth-running safety hand-wheel
The hand-wheel locking device for one-thumb operation locks the specimen head in the uppermost position, which is ideal for changing the specimen or the blade. A second locking mechanism on the microtome base allows locking the object head in any position.
The patented adjustable hand-wheel balance system for extremely smooth hand-wheel operation protects the specimen because the object head does not drop into the knife when sectioning is stopped.
Precision orientation system with clear zero reference point
The orientation mechanism of the Leica RM2245 sets standards of precision and is very easy to operate. An important detail: Calibrated controls make it easy to adjust a specimen to an exact zero position indicated by red pins or a measurable variable on the X/Y axis for re-cuts.
Lateral knife holder adjustment
The entire width of the microtome blade can be used without having to release the blade clamping mechanism. Using the entire knife edge saves costs, especially in laboratories with high specimen throughput. Three predefined stop positions (left, center, right) correspond to the width of a standard histology cassette.
