3.2 Instrument specifications
The Leica RM2265 is a motorized rotary micro-
tome.
• The specimen feed system with zero-backlash
and maintenance-free cross roller guides and
the stepper motor operated coarse feed sys-
tem are located in a dust-proof plastic housing.
• The instrument is equipped with a safety hand-
wheel with a handle that can be centered, as
well as a mechanical handwheel lock.
• All controls and LEDs are centralized in a
separate control panel.
All control elements are logically arranged in
functional groups and easily identifiable.
• The specimen retraction can be turned off.
In manual operation the retraction can be
adjusted. In motorized operation the retrac-
tion value varies with the selected sectioning
speed. An LED illuminates while the sample is
in retraction.
• The electric coarse feed operates at two
speeds. In the sectioning mode, the coarse
feed buttons have a STEP function.
• Four motorized sectioning modes (CONT,
SINGLE, STEP and PROG) are available as well
as one manual sectioning mode, the rocking
mode (ROCK).
In rocking mode, it is enough to move the
handwheel a short distance back and forth in
order to create a section.
