3. Instrument components and specifications
The Leica RM2125 and Leica RM2125 RT are manually operated rotary mi-
crotomes.
• The advance and vertical stroke mechanisms run on cross roller
guides that are free from backlash and maintenance-free. Both
mechanisms as well as the coarse feed system are protected by a
dust-proof plastic housing.
• The handwheel can be locked in the 12 o'clock position via the
handwheel handle. In addition, a handwheel brake mechanism allows
you to lock the handwheel in any position via a locking lever integrated
into the base plate.
• Sectioning is done manually by rotating the exceptionally smooth-run-
ning, counterbalanced handwheel. .
• The coarse feed function is operated via the coarse feed wheel on the
left side of the instrument housing.
• Section thickness is selected via a turning control knob and indicated
in the small window integrated into the instrument housing.
Section thickness settings from 0.5 to 60 μm can be selected.
• Both models are equipped with a slot cover preventing section waste
from entering the interior of the instrument.
Both the Leica RM2125 and Leica RM2125 RT are available in two ver-
sions:
1. Leica RM2125 / RM2125 RT, course-feed wheel left,
clockwise sense of rotation.
2. Leica RM2125 / RM2125 RT, course-feed wheel left,
counterclockwise sense of rotation.
The direction of feed of the coarse feed wheel is indicated by an arrow.
• A mechanical trimming function, activated via a lever and featuring 10
μm and 50 μm trimming thickness.
• Specimen retraction, designed to protect both knife and specimen.
During the return stroke, the specimen is pulled back from the knife by
220 μm. Prior to the next section, the specimen advances by the se-
lected section thickness plus the retraction value.
