7 Leica SM2400 - Sledge microtome
Accessories
The universal joint and the large specimen stage can
be easily interchanged after pressing the clamp lever
(3.6) down and removing the specimen holder. The
knife holder with integrated guard can be replaced
with the acute angle version (Fig. 7).
The safety caps must be placed over the
knife ends immediately it is inserted in the
holder.
If thick specimens are to be sectioned, the knife holder
can be raised by means of spacers (Fig.7). These are
fixed to the knife blocks (1.10) using socket head
screws.

The knife ends must be covered by the sup-
plied caps.
Cleaning and Maintenance
The sledge guide rails (1.20) must always be kept
clean. We recommend xylene or petroleum spirit.
Cleaning is accomplished most easily by moving the
sledge to and fro several times whilst cleaning both
sides of the rails. This ensures that dirt and tissue par-
ticles which have collected under the sledge are re-
moved.
After cleaning, the guide rails must be well oiled using
the special oil No. 601 available from us:
50 ml Order No. 0336 21783
500 ml Order No. 0336 21818
The specimen holder guide rails (3.2) should be
cleaned as follows:
Move the specimen holder to its uppermost position
using lever (1.1), then clean the rails with xylene or
petroleum spirit. No. 410 grease should then be ap-
plied.
When not in use, the microtome should be protected
from dust etc. by means of the cover.
