3-2 CUTTING MOVEMENT
The microtome of this cryostat is a rustproof
rotary microtome. The cutting movement is
carried out turning the handwheel.
The rotary movement results in the vertical
movement of the specimen orientation which
carries the specimen holder with the specimen.
The specimen is moved up- and downwards
close to the knife edge. The knife is clamped
securely into the knife carrier.
The section thickness is delivered at the upper
reversal point of the vertical movement. The
specimen holder together with the specimen
moves to the front by the size of the section
thickness, which can be selected on the
operating controls.
With the downward movement of the
specimen
, sectioning is carr
ied out. During the
return travel, the specimen is drawn back
automatically to protect knife and specimen,
which means that the knife can be used longer
and that the specimen is protected against
artefacts.
The number of sections made is indicated on
the section counter. After each downward
movement of the specimen holder, the number
on the section counter increases by 1. The
section counter can be re-set to zero at any
time.
The sum of sections made can also be seen
on the display. For this, trimming value and
sectioning values are added up. Section
counter and sum of section thicknesses can be
reset to zero at any time by means
of the reset
button.
More
over, the remaining travel to the front end
position can also be shown on the display. The
remaining travel, which is still available for
sectioning, is shown in microns.
