3. Instrument Components and Specifications

3.2 Instrument specifications

Basic instrument with mechanical trim function, lateral coarse drive
The Leica RM2235 rotary microtome is equipped with a low-maintenance, slack-free micrometer

drive, with vertical and horizontal specimen feed realized via low-maintenance cross roller

bearings.
The instrument is equipped with two independent handwheel locking systems for even greater

operating safety.
Leica's patented, user-adjustable force balance system compensates centrifugal forces arising

while cutting via a pretensioned spring for extremely light handwheel action.
Advantage: a heavy counterweight in the handwheel is no longer needed. The spring tension

is individually adjustable, corresponding to the weight of the respective attached specimen

clamp or specimen.
The patented specimen retraction system can be switched on and off by the user. The instru-

ment thus offers all of the advantages of specimen retraction while supporting work in "rocking

mode", i.e. without a full handwheel rotation.
We recommend disabling specimen retraction when working in "rocking mode".
The coarse drive wheel is ergonomically positioned.

chapter 5.1.2
