Leica RM2125 Microtome


The Leica RM2125 rotary microtome family has been designed for the routine histopathology laboratory where the manual use of a rotary microtome is preferred. The RM2125 is unencumbered by unnecessary features and equipped with all the functions needed from an entry-level microtome. The Leica RM2125 rotary microtome is the instrument of choice if you are looking for a microtome that provides unrivalled sectioning quality. The Leica RM2125 rotary microtome has been designed for effortless manual sectioning via a counter-balanced, exceptionally smooth-running handwheel. Storage space on top of the instrument housing provides room for sectioning tools and accessories.

The Leica RM2125 rotary microtome comes in two different versions – the Leica RM2125 and Leica RM2125 RT.

Features common to both the RM2125 and 2125RT versions are; they are equipped with specimen orientation, anti-tilt function, and a slot cover that prevents debris from entering the precision micrometer feeding system. The convenient, closely positioned coarse feed wheel promotes ergonomic and fatique-free trimming. The reliable precision-spindle micrometer feed combined with a special stable cylinder guide mechanism ensures low-vibration sectioning and highly reproducable results. The quick release clamping system can be operated with one hand and easily permits rapid change of the specimen holder thanks to a retainer system. In adddition to the traditional locking lever located below the handwheel, the handwheel handle is equipped with a safety quick-lock mecanism. When activated it immediately locks the handwheel in the upper position. A selection dial allows thickness settings from as low as 0.5um to a maximum of 60um.

The universal knife/blade holder E is equipped with a lateral displacement feature, so that the full length of the knife edge can be used without having to change the tension setting on the previously clamped knife or blade. A safety guard can be used to cover the knife edge, providing safety protection when not in use. The specimen orientation system with reliable anti-tilt function ensures accurate orientation of the specimen surface relative to the knife. The 60mm stroke allows sectioning of either cassette- or paraffin block-embedded specimens to a size of approximately 50 x 50 mm.
