3-5 KNIFE CARRIERS
The knife carriers are easy to use. They allow the
microtome knives to be clamped and adjusted as
needed. Depending on application, special knife
carriers are available.
3-6 MICROTOME WITH FAST
FREEZING UNIT
The fast freezing unit K-300 allows frozen
sectioning with the specimen temperature as low
as -45°C.
3-7 AUTOMATIC APPROACH SYSTEM
The automatic approach system is used for easy
approach of a specimen to the knife edge from any
distance.
When choosing the automatic approach system, a
sensor tilts towards the specimen and releases a
forward movement of the coarse feed. The coarse
feed turns off when a certain point is reached.
After that, the sensor flag tilts back against the rear
of the knife to give enough clearance for the
sectioning movement.
When passing the next upper reversal point
another coarse feed movement used as a correction
value is released. This way, the approach up to a
minimal distance of the specimen to the knife edge
is possible. If desired, the user can determine the
correction value by means of the coarse feed
functions on the operating panel (see 2-16,
automatic approach system).
